#RESIDENTIAL ARCHITECTURE PROJECTS
20th Street Residence
Faced with a client that wanted to expand their existing house in San Francisco's Potrero Hill neighborhood, and limitations placed on formal expression through the block's historic designation, architects SFOSL built up the house vertically and covered it in a material typically used for skateboard ramps.
A roof deck connected to the living area atop the building captures views of San Francisco, and the new covering over the old volume makes the building stand out on its block. The architects answered some questions about the project.
What were the circumstances of receiving the commission for this project?
The client contacted us after a project we did was published after an AIA Home Tour event in the city of San Francisco.
Can you describe your design process for the building?
It’s a fairly straightforward process. We gathered information, settled the budget, uncovered the real needs, made sure we had a complete understanding of codes – then we proceeded to maneuver among the issues we were faced with.
How does the completed building compare to the project as designed? Were there any dramatic changes between the two and/or lessons learned during construction?
We are happy to say that the building improved over time. In our experience, an absolute focus on solving the issues result in better projects – that improve as you move along – from something banal to something articulated.
How does the building compare to other projects in your office, be it the same or other building types?
The projects we do are made the same way – we give simple answers to complex challenges. They may appear different – but have the same formula. The main difference is the different clients – whom ultimately decide what architecture is for that particular project.
How does the building relate to contemporary architectural trends, be it sustainability, technology, etc.?
We find that budgetary consciousness is more of an issue today than before – and in that respect this project is really pushing the envelope. We didn't have a choice – and tried to make the most of what we had. We find that the most sustainable square foot is the one you do not build – and fiscally this gives new meaning to the word sustainable – we help the client save money, its environmental and it makes for better spaces.
Are there any new/upcoming projects in your office that this building’s design and construction has influenced?
We try to avoid preconceived ideas – but technical challenges in one project can certainly make us better prepared for the next obstacle in another project.
