This transformation of a dilapidated Victorian duplex near Holly Park Circle revitalized the front facade, while transforming the rear and roof of the project with dramatically modern features, finishes and amenities. The lower unit expanded down, to access the rear yard featuring a private garden and mature trees, while the upper unit expanded to the roof, to capture panoramic views of the park and San Francisco Bay waterfront. A very modern palette of natural white oak, dark metal accents, and dark and light stone are employed throughout.
