Charming cottage style in the front. Cool modern multi-level design in the back. We renovated this 4500-sf family house, located in San Francisco, to maximize views while preserving the architectural integrity of the neighborhood.
The complete remodel transformed the Pole Residence into to a light-filled, open plan jewel-box of a house, that now delights and serves the client. The focus of this project was on the quality of the space, not the quantity, allowing higher grade materials while remaining budget conscious.
This radical remodel of an Eichler-era townhouse consisted of replacing a confusing floor plan with an open-concept design. A new sky-lit, steel staircase connecting all three levels, transforms the formerly dark interior into a sunlight-drenched space.
