Noe Valley single family addition

A three-story addition to a century-old, two-story, one-bedroom Victorian house situated on a steep hillside in San Francisco's Noe Valley neighborhood adding apx. 1000sf of living space to accommodate the needs of a growing family.  The rear portion of the house has been extended horizontally expanding the kitchen into a great room, and vertically to provide two additional bedrooms and a small study.  The lower level has been expanded to provide additional storage space adjacent to the garage and a guest room opening onto the garden.  Old and new are joined by a skylit central staircase connecting all three levels. Materials were chosen that complement the existing structure while giving the new portion its own identity and a warm, contemporary feel.  Window locations were carefully chosen to take advantage of the sweeping views of San Francisco and the bay beyond.  Sustainable strategies include the use of fly ash in the concrete of the new foundations, FSC-certified lumber, solar water heater, hydronic radiant floor heating system, reclaimed wood flooring, low VOC paints and finishes, urea-formaldehyde-free materials with high recycled content, high-efficiency appliances and lighting fixtures, and pre-wiring for a future photovoltaic array.
