A cookie cutter developer three bedroom duplex was transformed into a four bedroom family friendly home complete with fine details and custom millwork. A home office, artist studio and even a full laundry room were added through a better use of space. Additionally, transoms were added to improve light and air circulation. Instead of providing separate bedrooms for the two young children, we designed a single large bedroom with a sliding wall of Douglas fir. Half of the space can be configured as a playroom, with the children sleeping on the other side. The playroom can also function as a guest room. Photo by Ofer Wolberger
