On Vashon Island, about 20 miles southwest of Seattle, architect Seth Grizzle designed a 440-square-foot multiuse structure for his clients Bill and Ruth True.
To pay homage to the original building, Graypants salvaged some of the old walls for the flooring, sections of which can be lifted to reveal embedded mattresses for sleeping or daytime lounging. This hide-and-reveal theme plays out elsewhere: a custom Corian bookshelf converts into a speakeasy-style bar for entertaining. In the back, the firm left an L-shaped section of the original garage walls in place; it shields an outdoor shower on one side and functions as an entry hallway on the other.
The Trues host parties in the glass-walled structure, located steps from their vacation home, or they escape to it to catch some rays and read a book. Bill reclines on cushions hidden under the reclaimed-fir floorboards that are propped up with Sugatsune hinges.
