Moving Up on Potrero Hill
Average Rating: ( 0 votes)
When the client moved into a 1900s cottage in San Francisco's Potrero Hill neighborhood, he was a bachelor; when his life expanded to include a wife and three young children, the house took the leap as well. The modest shingled cottage never had pretensions to a particular style, and in the course of the last century, had remained half-hidden behind trees on a wooded lot. It was this low-key presence that architect Cary Bernstein, who is a member of the Remodelista Architect/Designer Directory , was careful to preserve in her major renovation of the house. "The trick was to keep some of the quirkiness of the cottage, and to add our own layer of history," says Bernstein. "We expanded up, adding a third floor, to avoid interrupting the garden surrounding the house." Photography by César Rubio . Above: Bernstein transformed the cottage into a light-filled modern home. From the street, it appears to be two stories; the first floor steps down the hill behind. The home's original Dutch door is still in place (now painted black). To see the building before, go to Potrero House and go to the last thumbnail in the gallery. Above: Adding a third floor did not require any extraordinary measures, thanks to a solid foundation and strategic choices by Bernstein, who used external steel framing to brace the house. A frame around the double-height windows (L) and a trellis over the front door that anchors the house to a shed (R) are key structural supports. Above: The original ceiling, with its mix of planking in three different sizes, became the inspiration for the new facade. The flooring is reclaimed oak barn siding.

A Blu Dot Knicker Chair is at the built-in desk. Above: To the left of the front door is a side entry that goes straight into the kitchen; the breakfast nook has a built-in bench for shoes.

Above: The stairs are recognizably old-fashioned in shape, but the railing has been reinterpreted with modern steel spindles.
