This remodel and addition completely reimagines a 1940s row house at the top of a steep block above Eureka Valley for a young couple from China. Clean lines and crisp blacks and whites gradually open up more and more as you rise through this home with its reverse floorplan. A new folded jewel-like penthouse caps the project, sheltering an airy loft-like living level, with space and light flowing up and over the fourth-floor family room to the third-floor kitchen, living and dining below. Panoramic views of the skyline and twin peaks are captures from every angle, turning the home into a lens. Refined details such as a folded steel plate stair, minimal white cabinets and silky honed marble slabs manifest the overall design concepts at every scale, creating a peaceful sense of place.
