It’s been a month since we moved into the the new ADU (accessory dwelling unit). Despite the heavy rainfall and intermittent delays, our spirits were not dampened!
After waiting anxiously for 18 months, this big baby was delivered! The wedge-like irregular shape created by the rear yard setback integrates a kitchen, dining and living area on the ground floor. The main windows facing west provide generous natural light and ventilation. Combined with high 11′ ceilings, these public areas feel open and spacious. A double patio door leads to the exterior redwood deck expands public spaces for outdoor entertaining.
Naturally finished wood windows, shelving and details are used throughout the unit to complement sealed concrete flooring on the ground floor and wood flooring above. Walls are painted white throughout both levels.
The kitchen service area combines overhead matte gloss cabinets with wood base cabinets. A cozy picture window frames a 70-year old juniper tree outside. Painted wood shelving displays dinnerware and a large display space is reserved for a future surfboard!
Opposite the entry door are built-in cabinets that maximize unused space under the stairs. Coats, pantry, recycling bins and additional storage are tucked behind blind doors. Special attention was paid to proportions, materials, and craftsmanship.
Half a landing up, the basement room inside the original house was converted to a bedroom and bath suite. the bedroom ” inner sanctum ” may be used in the future as a mini- screening room. Both bathrooms in the ADU utilize radiant floor heating. Wood shelving adds a luxurious spa-like touch to each.
An open, double-height stair provides a view towards Parnassus Heights and Downtown San Francisco. The master bedroom/bath suite and large sitting area connects to an upper patio deck. In turn, it connects to the kitchen dining area of the original house. Large windows catch an abundance of natural light and spectacular views of the Pacific Ocean, Richmond District, and the Golden Gate Bridge. Like those from penthouses over New York City’s Central Park, this view captures Golden Gate Park and the greenery from above its tree canopies.
Window trimmed in natural wood finishes and natural oak flooring complement the 9′ high exposed wood joist ceiling. It’s a reminder of the extensive rough carpentry work on the building performed by J&J.
The exterior of the addition is clad in exposed wood vertical strips stained in black and walnut finish over cedar. Each window is framed with similar wood finishing. The redwood deck connects to the ground floor living space.
An example of the myriad details and instructions that make this project so remarkable is shown below. Jeff marked up plans and photos to explain the design intent. Here, he describes guard rail spacing to provide wind protection, natural ventilation and visual relief all in one solution.
This example is only a small indication of the dedication and care that was taken to create a beautiful and timeless design. Harking back to the three goals for the project–to develop a rental unit; to create multi-generational housing; and to enable future aging-in-place–all were met and our expectations were exceeded.
This post is dedicated to Julianne, the Daughter of Fong & Daughter, for her tenacity, commitment, and relentless desire to go above and beyond the call of duty. We love and cherish you Julianne, and partner Jeff, for your work that will last for many generations to come!! Dear Felix is one lucky and happy fella with you as his parents!! With Love and affection from the Fong of Fong & Daughter.
Here’s a quick video of both floors of the ADU and the bedroom suite at the half landing. Let me know if you have questions or comments!
It’s hard to believe that our ADU project will be completed next month! The latest photos below are captioned and describe the finishing process for the third and final phase of construction for the interiors.
With final inspection and a few finishing touches left to complete, we plan to move in by the end of January 2023! Thank you all for following our progress on this once-in-a-lifetime experience! We hope you have enjoyed the ride!
Together with J&J (Design/Build team) and Fong & Daughter (Planning and Design), we planned, designed, and physically built this entire 1000 sf addition to our existing house. Each member of the Fong & Chou Family are grateful for the opportunity, manageable weather, and our good health to finish the project.
Dear Felix deserves a special mention. He endured the trials and tribulations of mom’s intermittent absence from the homefront to the battlefront. Initially he could watch all the action from the dining room window, as many of you have witnessed in early posts. But as time progressed and the walls were enclosed, he lost his viewing stand and parental supervision. (that is, his supervision of his mommy and daddy!)
Nevertheless, he was a total professional and cooperated with us wherever he could. He observed the daily development and progress as his parents built a home for his family, his grandparents, and generations for years to come.
Spoiler Alert: Next month you may see a regular post of Travels with myself and Others in ….Paris!! Until then, Happy Holidays!
If you followed the last couple of posts, I took a hiatus from the construction of the ADU and went to Germany for a couple of weeks. The main event was the Bayreuth Festival, where I sat through 17 hours of The Ring Cycle amidst a primarily German crowd. Check out the posts if you are interested in Germany and opera.
But this week it was back to the grind. Progress on the ADU project continues slowly, but surely. With the challenging first two Foundations and Rough Framing phases behind us, we are now energized by the advent of the third and final phase for Infrastructure and Interior Work.
There is only one exterior opening outstanding before the project can be officially deemed “sealed and weather-tight”. The two-story hallway picture window was temporarily covered in plastic, then hoarding used to cover the large opening. All the rest of the windows have been installed, including the large French patio doors to the exterior deck and the sliding doors to the breakfast nook. Additional weather-proofing details, such as roof and window flashing, will be applied following the stucco patching on the original house.
The Building’s Respiratory, Digestive and Circulation Systems
Like the human body, a building is reliant upon its respiratory (heating, ventilating and air conditioning system), digestive (plumbing) and circulatory (electrical) systems to function properly. Once the skeletal system (structure) is formed, the other layers are added.
Infrastructure defines our modern-day living standards but is seldom seen or appreciated. Without the effort of HVAC mechanics, plumbers and electricians, we would still be living in caves. These contractors were now front and center stage.
They drilled and sawed through and between stud walls to place plumbing pipes, vents and electrical outlets. Their work is grueling as we watched them twist and screw sewer lines, vents and ductwork in between walls and in awkward crawl spaces. We depend on their ingenuity to fit conduits, connectors, and pipes within confined spaces to provide us with essential juice and means of discharge.
We seldom think about how crucial these elements are until they are missing or misplaced! And of course, the brains are stored in the controls, meters and sacred electric panel.
After the plumbing and electrical work, blanket insulation was installed. Upon successfully completed inspections, sheetrock was placed on both sides to form walls, with cutouts for electrical outlets and switches.
Rockin’ and Rollin’
Before we were able to pause and catch our breath, the drywall was quickly put throughout the unit. It left a marked visual change to all the spaces– we could no longer telescope through the rooms! The windows were suddenly framed by opaque walls and views popped out of each space. What a joyful sensation after such a long wait!
The drywall scope is quite an intricate process. After the drywall is installed over stud walls packed with blanket insulation, gaps between panels are taped, “mudded” or sealed with wet plaster, troweled, and allowed to dry for a couple of days. The mud is sanded to a smooth finish so there are no flaws on the surface of the sheetrock. Despite having seen this process over hundreds of commercial and residential projects over the course of my career, it’s not the same as watching it unfold in front of you real-time. The swiss cheese gouges in sheetrock are no longer visible to the naked eye. It can be gratifying but only after endless hours of what feels like watching the grass grow.
The Kitchen Renovation
Without a functional kitchen, the stress and anxiety built to fever pitch . Washing dishes in the bathroom vanity sinks and avoiding clogging food particles in the narrow 2″ pipes was a daily brain bender.
Following drywall wetting and drying processes, the primer and paint was then applied. Different paint finishes, such as flat, eggshell and high gloss, determine the amount of light reflectance and resilience. The higher the sheen, the higher the light reflectance. In the kitchen, we wanted to maximize the light reflectance due to the limited amount of natural light. If you remember from one of the earliest posts, we sacrificed the kitchen window to maximize the ADU.
The kitchen now has no natural light. Using higher light reflective paint helps to capture as much light from elsewhere as possible to mitigate limited daylighting. Most of the walls were going to be covered by high gloss overhead and base cabinets so the wall color was moot.
Laundry flooring led me into the world of engineered products. You can now buy vinyl floor tiles that do not require grout. They are “keyed”, or grooved to the next piece as you would expect Pergo or thicker simulated wood flooring. The profile of the vinyl tile is less than 1/4″ thick, but manufactured with a laminated surface, a composite sandwich in between, and then with a plastic backing. These new engineered products command a premium price, but it is worth it for ease of installation and a more durable material.
After considering products at Home Depot or Lowe’s, I decided to purchase the product at Floorcraft, an “old school” retailer down on Bayshore. A sales rep waxed poetic and shared his years of experience as a flooring installer with me. As a real-time responder to my endless questions, he sold me on his recommendations. There’s still something to be said for customer service where you can see the whites of their eyes.
Watch for the next post to see the finished kitchen and more steps to the finish line for the ADU! Don’t forget to comment or let me know if you have questions about the design and construction process!!
Wagner pompously stated “there’s Bayreuth…and everywhere else. Its hard to escape this dominant patron in the tiny city of 75,000.
This may sound incredibly arrogant, but the attitude is understandable when you are here. It’s an out of body experience to infuse the soul of one of the most enigmatic characters in modern history.
Germans adore their musicians, and support their favorite sons actively with state funding, reduced rate performances, and frequent indoctrination by researchers who uncover new tidbits of information about their musical gods and heroes. If only Americans would be so kind to their own artists and creative community!
But back to the Wagner drum roll. His family were prominent residents of the town and managed to nab a slot in an idyllic park in the middle of the city. Then he built the festival opera house on a hill overlooking the city to present his work. His Ring cycle, four operas over six days and 17 hours of entertainment, opened the opera house in 1876.
For those unfamiliar with Wagner, you might wonder what the whole fuss is about. It would not be a stretch to say, at least among his disciples, that he represents not only the pinnacle of German opera, but of Western opera.
In the Ring cycle, Wagner not only wrote his own libretti or poems (in this series to tell the saga of a dysfunctional extended family), but he also scored some of the best classical music ever. He was an intellectual snob but succeeded transformed music with emotional skill and content.
Fast approaching its 150th anniversary in 2026, the Bayreuth Festival has been tooting its horn for quite some time. No other musician has attempted to build a monument in which his own works could be performed. Doing so seems pure folly. Wagner went ahead and did it anyway.
There’s no doubt Wagner was anti-Semitic. The Wagner House museum displayed some of his writings, but claimed that it was his family who embraced his writings and promoted them during the Nazi regime.
“There’s Bayreuth…and the rest of the world…”
I don’t know if you know anyone who’s been to the Festival, but I can claim only one other person from the States I know crazy enough to have come here. My friend warned me that Wagnerians take their religion seriously. Members of the Wagnerian society meet regularly, then proselytize after being trained in intricate Wagnerian minutia.
I’m only a neophyte, but I confess to ordering three books on Wagner. I felt compelled to weaponize myself in case my knowledge was put to the test. Aside from a narrative version of the Ring, a German-English paired translation of it, and a scholarly analysis of its music and history, I felt I had earned proof of my devotion to Wagnerian principles and thereby gained access to Valhalla.
The Festival Hall
Nothing too remarkable, except that it perches on a heath overlooking the town of Bayreuth. My accommodation was a fast half-mile walk and perfect for the occasion. The opera house accommodates 1500 eager opera lovers, a cozy size for the acoustics of unamplified voices and the way opera should be heard. That’s nearly half of the 3800 seats in the cavernous Metropolitan Opera in New York City.
The orchestra sits under the stage and is hidden so the audience is not distracted by the musicians. They huddle like Nibelungen in the cave, chipping away and churning out musical notes. Wagner exercised musical chairs to reposition players according to the sound they projected to the audience.
Every seat is a good view. The wide cone of nearly 70% makes everyone feel equal to the best. The down side is that, with nearly 50 seats per row without aisles, you have to skip the cocktail champagne to get into your seat in the middle or incur the side seaters’ wrath. Everyone grits their teeth until the center sitters arrive, then are finally able in domino fashion to seat themselves. By the last half of performances, late arrivals lost their pole positions and got relegated to the edges as others were instructed by ushers to move into vacant seats. That suddenly upped our real estate 10%.
I made the mistake of forgetting that cushions are available from the garderobe. During my first performance of Das Rheingold, I squirmed between drifts of head bobbing. I had not prepared myself properly with an obligatory nap beforehand. Rushing to Bayreuth with three changes on the day of the performance and buzzing from the glamour of being there was a fatal combination.
Catering is well planned for a variety of tastes and affordability. I tried most of every type of station—from sushi to ice cream, bratwurst to cold steak platters. I did pass on the 70€ buffet only because I didn’t think I could gorge on all that was offered within an hour!
The controversy over Wagner’s anti-Semitism lingers. Displays of prominent Jewish composers and musicians who contributed to Wagner’s success were posted. You couldn’t help but wonder if was only a token effort.
Having now seen all four operas of the Ring Cycle, I was intrigued by the visual changes to the traditional story. Performers wore contemporary fashion and gestured in current body language. Think Kardashians. Think Trump. Think downfall of society.
It took awhile to get whetted to the visual style. The director transformed iconic fairy tale characters into trash behavior. They strutting in stilettos, grabbed guns for attention, and constantly glued themselves to cell-phones. Did we really want to see a fantasy playing out the way we witness life every day?!? Where are my hero and heroic heroine figures that I came to wish upon a star with?
I tried my best to keep an open mind, but I struggled in the end to accept the director’s imagery. For me, an original story with timely relevance today expressed by Wagner in word and song over 150 years ago did not have to be a literal translation. This ironically backfired and left a very bad taste in my mouth not just for this stage direction, but also caused me to question Wagner.
Take my one interpretation and multiply it in a room by 1500. One of the most startling and entertaining parts of the evening was witnessing the audience reaction to each performance. The noise level steadily escalated to a crescendo in the fourth and final act of Gotterdammerung.
There were two competing aspects: superb singing and horrible visual effects. This is not the ho-hum nervous applause you expect from any American curtain call, embellished with an obligatory standing ovation.
German audiences are much more reserved and discriminating. They give standing ovations for performances that are genuinely exceptional. No grade inflation. But there was no standing here. The Germans were too busy in their seats stomping their feet while clapping furiously for minutes on end!
Simultaneously, wild jeers and boos were spat out while foot stomping. No one rushed off to catch taxis or buses, but remained in the theater far too entertained by the raucous scene to think about lost time. It was just too precious a moment to miss. This is one of the rare times I saw so many genuinely smiling faces in Germany, as if it were the community spirit suddenly unleashing itself. My, what a refreshing group therapy session that was!!
The Rest of the World
There’s still plenty to see in Bayreuth if you aren’t an opera fan. You can indulge in 1. another opera house recently made a world UNESCO site. Margravine Wilhelmine of Brandenburg-Bayreuth (1709-1758) was the Prussian king’s daughter and favourite sister of Frederick the Great.The baroque opera house was dedicated to the wedding of Wilhelmine’s daughter. An opera buff and some time theatre director, Willy chose high drama to showcase her daughter’s betrothal.
2. Wagner’s house. OK now we get it. He was of the gentry and came from a prominent family. Nice grounds to prove that Wahnfried deserved its name—to be free and satisfied.
No, I wasn’t traveling to Bayreuth in the winter. This is a model of the opera house in Wagner’s house. Designed by Semper, it has strong resemblance to the shape and character of the Dresden Opera House that I love. Despite the uncomfortable seating in the Bayreuth operahouse, the acoustics are worth experiencing.
3. The Royal Palace (see header above): the royal court of Markgraf Friedrich von Brandenburg- Bayreuth landed here, and used the mid 1700 rococo facilities to impress and entertain the militia. No doubt a fun place to have a blowout. They even recreated an Italian grotto in a room where you went in full regalia to gawk at an imitation of the real world. Fortunately it was before Wagner’s time or he surely would have left an impression on Wilhelmina.
A sojourn in Nurnberg, about an hour and a half by slow train and bus to visit the medieval section of the walled city, where the Albrecht Durer House was located. I also visited the National Rally Grounds of the Nazi Party. It was a vast field of multiple football fields to promote the training and display of military might for the German people.
After two years of self-imposed travel black-out to Europe, I finally decide to take the plunge for an opera trip to the Bayreuth Festival in Germany. After applying for two years in 2017 and 2018 unsuccessfully, I was offered a slot to purchase tickets for Wagner’s Ring cycle for 2022.
Normally all performances are sold out years in advance. You qualify after four years of application. I’m sure the COVID pandemic was a big detractor for many, so my chances of getting tickets were improved. I deliberated back and forth until I was advised by others to “live my life as I would have normally before the pandemic”.
I am taking a break from the past year’s construction project. If you have been following the story of the ADU (accessory dwelling unit) under the direction of Foreman Felix, we will resume after this two week diversion!
Munich–the Gateway to Bayreuth
After a direct flight from San Francisco to Munich, it felt odd to suddenly be plopped out of nowhere to a country that I had studied and admired so much. Being in Germany reminded me of all the reasons I became a Germanophile: Citizens take the environment and sustainability seriously; clean, predictable, comfortable public transportation; appreciation for and attention to architectural detail; and safe streets (except for bicyclists running over pedestrians).
Refreshing my German language studies before coming helped to prepare me, despite a huge reliance on fully capable English-speaking Germans. The immediate sensual experiences were the lush green countryside, church bells ringing, and the distinct lack of smell or taste.
This summer, scores of public transport agencies have joined together to offer a special incentive to use their services. For a flat price of 9 Euros, passengers can ride any of the local agencies throughout Germany for an entire month (June, July and August). You can get just about anywhere in Germany, as often as you want, for the price of a round-trip subway ticket!
Many residents were concerned that trains and buses would be overcrowded. Rush hours and popular tourist sites need to be avoided, but the summer months are normally the lowest ridership. I wondered if statistics were due to the high volume of Germans traveling outside the country during summer months pre-Pandemic. In any event, it appeared that my three changes to reach Bayreuth were completely manageable.
Dachau Memorial Site
Worry-free travel encouraged me to venture to Dachau to visit the grim Concentration Camp outside of Munich. Now known as a Memorial Site, it was a second visit for me. It was not as jarring as the first, when memories were raw and more startling.
Mature beech trees and religious institutions are now located on the site to reduce the impact to visitors. Audio-visual materials translated into English helped to describe what happened. Efforts to explain economic hardships after World War I and during the Thirties gave perspective on the past. When the Americans arrived in 1945, prisoners were freed. Unfortunately, the advent of the Cold War distracted the war trials. Few were held accountable for causing the Holocaust.
Alte and Neue Pinokoteks and the Modern Pinokotek
This extensive array of Western Art from the Greeks to Impressionists propelled me into full museum battlement. I covered many miles by foot and found the masters including DaVinci, Raphael, Durer, Van Gogh and Manet. I was delighted to find an Egon Schiele, one of my favorite artists. And the pastel collection was a great value lesson on how the medium achieves more luminosity over oil paintings. Pastel artists struggled with the chalky powder, so I felt vindicated by my shared frustration.
From the Alte Pinothek to the Modern, I searched specifically for any display of Thonet bentwood chairs. My early education as a design major gave me an appreciation for the best industrial design and chair production. The Modern Pinothek did not disappoint–in fact it showcased a chorus line of beautiful period Thonet chairs in chronological order!
In the trendy Schwabing neighborhood where I was staying, I stumbled into a woodworker’s shop specializing in Bentwood refurbishing. Like many Germans in August, the proprietor was on “urlaub”, or vacation. A peek through his shop window motivated me to follow up with him after my return to the U.S. I also learned from conversations with a retail supplier that, while “Thonet” is produced in Germany, “Brueders Thonet” is a separate company out of Vienna, Austria. Important to know the date and source of production when searching for vintage pieces.
Several spins around Schwabing, the equivalent to St. Germain de Pres and near the Ludwig Maximilian University, yielded a boutique selling exquisite hats and headpieces, an academy for ancient Greek Sculpture where you can sketch to your heart’s delight, cute babies, and a yummy French bistro next to the hotel where I stayed.
(Note: the copper pipe in the featured photo above would never survive in San Francisco! Ah…such trust…)
I’m off to Bayreuth, about three hours by train-bus-train to see Wagner’s Ring Cycle! Sixteen hours of sitting in a theatre seat could just about get me around the world! Yes, the gods must be crazy and I am about to find out.
Don’t forget to write from wherever you are! When was the last time you were in Germany?!?
Completing interior spaces provides great satisfaction in experiencing each room after many months of planning, design, and construction.
The new challenge is to work efficiently within confined spaces. Temporary storage of materials and equipment occupy space to be finished, so careful logistics and organization are needed to save time and effort. Lumber is very heavy and cumbersome to move!
Designing the roof parapet was part of the permit submittal and approval. It was important to make sure that the assumptions for the design were correct. The height of the roof parapet had to be confirmed before waterproofing could be applied to the roof.
In order to maintain minimal impact on the neighborhood and balance proportions viewed from all sides, we checked the height of the parapet from across the street. It didn’t hurt to get some friendly input from our neighbor.
One loop thrown at us was wet weather–not the kind of driving rain that predictably hampers a construction site in the winter–but “the coldest winter I ever spent was a summer in San Francisco” kind of weather. The pebbly fog hung around for weeks in late July and early August–forcing us to delay finishing the waterproofing and window installation.
Finally, the skies parted and the grayness dissipated. The roofing insulation and waterproofing membrane were added after completion of the roof and parapet. Note the difference in the weather from the photos!
Being located in the rear yard was ideal for the ADU, but it posed temporary challenges for providing delivery access. Fortunately, the side of the house was just level enough for large trucks to move supplies as close as possible to the back. Felix had a field day watching the speed and skill with which drivers were able to shunt and offload heavy loads.
Part II The Core (Weeks 48-54)
With the end of Rough Framing and the start of the third and final phase for Interior Finishes, we happily shifted gears. Previously, it felt painfully slow as we hurried and then waited for action. With multiple possibilities and combinations of skilled labor and materials, we were often faced with making decisions that could impact the project later.
For the exterior walls, waterproofing was smeared over the nails and knotholes forming scabby polka dots to allow for the inspector’s scrutiny. Then, the rest of the waterproofing was applied to the exterior walls to form the underlayment for wood siding.
After the windows were installed, it no longer felt like a shell. We could really visualize being occupants in the space!
Passing rough inspection was a red-letter day. It officially determined the completion of the second of three construction phases. With rough framing behind us, we could proudly identify ourselves not only as owner and architects, but builders as well.
Coming Up: A diversion to…Munich and Bayreuth, Germany next!!!
This month’s activities includes installation of windows, building the stair between two levels, and waterproofing of the exterior skin. Both the roof and exterior walls need good moisture protection, so additional care is being taken to check details with a waterproofing consultant.
In addition to interior wall framing, shear walls between the existing house and new addition have been added. You can see a portion of the wall along the stair to the right in the photo below. In the next photo, deck rails have been built. The roof parapet will be built next, providing protection for a future deck and extending the roof approximately 42″.
Miscellaneous windows and exterior doors were ordered, and planning for interior finishes and equipment went into high gear. While we thought that ordering materials and products would create issues with delivery and material availability, the problem was not as great as imagined.
There are always alternatives if you are flexible about the products, and since we were not providing custom or high end finishes, we could work around lead times and locally available products. Out of the items for kitchen casework through Ikea, appliances through a discount broker, and plumbing accessories appear to be within reach, at least at his point before actual ordering takes place.
Wind rather than rain is a deterrent to working on site. The gusty coastal weather has been downright unpleasant at times and chills you to the bone. We can’t wait for the autumn weather when the winds die down, although we may be in for some unpredictable air quality from fires.
With the existing kitchen and dining room out of commission, it has been a challenge to prepare and eat meals. On top of that, the ambient temperature in these rooms average around 50 degrees. The heating bill was over $700 last month until we realized that the exposed air was sucking all the heat out and the thermostat was registering the coldest past of the house!
Felix has lost his viewing stand from the dining room window and can only wistfully catch glimpses of Mom and Dad during bathroom breaks or snack sneaks. The roof obscures all the active work taking place inside the new space, so there’s no opportunity to view activity from above when roof joists were previously open and exposed.
As an alternative, Felix has watched street construction down the block. His beloved dump trucks, bulldozers, and and excavators are all readily available in full operating splendor during his daily strolls. They complement his readings from favorite construction books. He never tires of hearing them again, even on the sixth or seventh time in a row.
Even as an architect, it is difficult to appreciate the complexity and skill it takes for homebuilders and contractors. Unless you are living and breathing on the site 24-7 as we are, you are unaware of the active thinking, eye-hand coordination, and immense challenges it takes to build a structure from scratch. This giant sculptural baby is taking form and unwinding each day, with distinct progress and satisfaction gained.
The Second Story
After completing the floor joists and the subfloor for the second level, we began constructing the exterior walls. The master bedroom and bath will be located on this level.
Walls were first assembled on the floor, then tilted into place with “stoppers” to hold the wall in place. Finally, the sill plates were nailed to to floor and voila! The structure defines the edges of the rooms to be finished in the final phase of construction. Glimpses of the Pacific Ocean and Golden Gate Bridge make this monumental effort worthwhile.
Hoisting a heavy prelaminated beam in place became the next challenge. At 24 feet long and a heavy member, the beam arrived by truck from Golden State Lumber. It caused a brief sensation on the block as neighbors are not accustomed to seeing large scale deliveries for construction in such a quiet, sleepy environment.
The process was swift and completed in a matter of hours. A simple hoist raised and positioned the beam into place.
Once the prized beam was unwrapped, roof joists could now be quickly built to attach to the main spine and to enable roofing to be installed over the joists. The joists and beams formed a chorus line where the music and dance of the musical all came together!
Because the roof joists were going to be exposed, each member was hand selected and its exact position in the chorus line was determined. Additional care was taken when plywood roof sheathing was installed to avoid any exposed nails. There was no room for error here.
At the same time, scaffolding was erected along two sides of the structure for installation of windows and exterior material. When the roofing material is installed, the entire structure will be sealed and ready for the final phase–interior finishing!!
The Felix Factor
Stay tuned as Felix sees the unfolding of the third and final phase of our on-site construction project! Don’t forget to write home!
The bone dry weather has serious outcomes for the Bay Area and California, but for us the lack of rain has helped us. So far, we have been able to continue building the ADU. Where we sit on a bluff, strong winds have been more problematic.
Still, there are many other challenges. A two-person crew, trained as architects, are learning to become builders. They must make many decisions about basic construction– how to organize the means and methods of building, order materials and equipment, and master the tricks of the trade.
Problem-solving on the spot may not happen as quickly as expected, particularly as each choice affects the next task or decision. Building a new structure connected to an existing residence requires complicated tie-ins and repair to areas where the exterior skin and window were removed. Eventually, solutions surface and we were able to move forward. Teamwork and collaboration are the keys to working toward a common goal, along with communication and trust among team members.
Recap of First Floor Walls
As you may recall from the previous post, we had completed the first floor wall framing. The video walk-through below gives you a real-time sense of the space from the end of the unit, containing the Office, Living Room and Dining Area. You can also see the small window along the north side in the kitchen and the view of the entry into the unit.
Architects think of building systems as analogous to those in the human body. Plumbing systems are similar to our digestive system, electrical systems are like our central nervous system, and ventilating systems are like our respiratory system. The beams and columns form the structural system, just like our bones do. So yes, creating a building from scratch can feel like a powerful act.
As we continue on our journey to build and complete the ADU, we will be referring to these building systems as they are developed throughout the construction process.
The Second Floor Framing
Wood construction uses many of the principles we learn as children when we played with blocks and legos. But the actual joining together of materials and elements require some additional skills. It helps to think three dimensionally and have a sculptural understanding of shapes and planes. A complex structural design to address an irregular shape and site configuration raised the bar for these skills.
After last month’s challenge constructing the wall framing for the first floor, the next hurdle was the floor for the second story. Referred to as a “diaphragm”, the combination of plywood sheathing and floor joists stabilizes the walls below when the two vertical and horizontal planes are joined together. They now form a box that work together.
In the video above, you can see the walls of the first floor below. They support the upper floor. At the edge, a 3 foot cantilever extendsover the first floor walls to provide more floor area for thesecond story above. It will be one of our last opportunities to “see through” this space before it is covered up.
Completing the Floor for the Second Floor
With the plywood sheathing attached to the floor joists, we finished the second story subfloor! The 3/4″ plywood is keyed with a tongue and groove system so they attach and seal together at the edges.
In the video, you can see that the wall framing for the north wall of the second floor Master Bedroom has been built on the ground. The completion of the second floor provides a usable work surface for building the exterior walls before they are tilted into place.
This is the latest photo of the second floor exterior wall erected yesterday morning. The master bedroom window frames a view of the Golden Gate Bridge above the tips of the 50-year old junipers!
Foreman Felix continues to watch from his control tower, except that now he can see his crew directly in front of him at the same level. He joins the conference on the mound while having a refreshing mid-afternoon snack.
Foreman Felix had time to get away every now and then from the job site. He managed to raid the kitchen pantry and found a treasure trove of tasty new toys hidden within.
Stay tuned as the story (the second story) unfolds!! Don’t forget to write home!
The first real sense of seeing the interior space and the spectacular view from the office window was thrilling to see. We could actually witness the results of many months of planning, designing, and building our ADU (accessory dwelling unit).
Still, more heavy construction work was ahead of us. Two steel beams arrived from the fabricator and stared us in the face: more calculating and logistics on how to erect these 800-lb gorillas. It took a few days to prepare the existing structure and get the necessary equipment to erect them safely.
Headers and Footers
After getting refreshed over the weekend, Team J&J erected the two steel beams. With help from the rented lift and a portable scaffold, each beam was placed to form a 3′ overhang over the deck. The overhang provides additional floor space for the upper level and also shading for the windows on the first floor.
Once the steel beams were placed, the edge beams to support the upper floor were installed between the steel flanges.
With so little tolerance to work with in joining all of the angled walls, the wood beams required several attempts and shaved edges in order to fit them inside the steel flanges.
Finally, a perfect fit!!
A Footnote: Multi-tasking in the Front Row Seat
Felix continued to dominate the box seat to watch his crew staying on the job. While he kept an eye on them, we watched his new skills as he learned to enjoy the freedom of feeding himself!
Onward and upward! Next in store will be floor joists and stud walls to finish the first floor, and window installation. Stay tuned for more fun, and don’t forget to comment!
