Suzanne Stefan, co-founder of Seattle-based architects practice Studio DIAA, designed her and her husband’s home, The Portage Bay Float Home, by the shore of Lake Union within Seattle’s city limits. It was built on thick logs, tied together with wood or steel stringers. “We wanted to feel immersed in nature—we’re surrounded by water and a lush garden. A living room with skylights invites light inside. Next to it are bedrooms and a bathroom. Each room has floor-to-ceiling glass doors and generous views of the landscape. A wraparound deck provides areas to relax.” Her family is sporty, and the house is a great base from which to swim, sail, paddleboard, kayak, and dive.
