This down-to-the-studs remodel of a full-floor condominium in the Castro brought light and flow to a previously dark and chopped-up space.  An ensuite master bathroom was added.  The new kitchen features walnut and white cabinets, Caesarstone counters, sculptural backsplash tile and Thermador appliances.  Whitewashed oak flooring expands the space, unifying the new layout.
