When the Zimmerman family settled in Seattle, Washington, in the late 1990s they bought a 1,100-square-foot Craftsman built in the 1920s. Fast-forward to today. Not wanting to leave their beloved neighborhood, but hurting for space, they enlisted the help of local design-build firm Ninebark to create a separate living area. Working from sketches that the residents had from their uncle, Gary Schoemaker, an architect in New York, Ninebark realized a refined structure that serves as a playroom, office, and guesthouse for visitors, complete with a kitchenette and full bathroom.
