Hoshide Wanzer Architects, together with Dyna Builders, drew inspiration from the Costa Rican philosophy of Pura Vida—celebrating simple pleasures and a relaxed pace of life—to create this floating house on Portage Bay, a neighborhood in Seattle, Washington, that offers a dynamic connection to nature and the ever-changing waters. The design is flexible and responsive, allowing the home to adapt to both environmental and social conditions.

A 1,780-square-foot glass-walled pavilion facing the lake can open on three sides for unobstructed access or close off with solar shades for privacy and seclusion. The two-story structure features a private, sheltered area with rooftop deck access, perfect for gatherings, while maximizing expansive lake views and fostering a tranquil, intimate living experience.

What We Love About This Home

What we love most is how effortlessly this floating house in Seattle blurs the line between indoors and out. The glass pavilion opens on three sides, making the bay feel like a living room. We’re also drawn to the rich material palette of walnut, cedar, and terrazzo that brings warmth and texture without competing with the water views. The rooftop deck with a fire pit overlooking Portage Bay is the kind of space that makes you never want to leave.

Tell Us: What’s your favorite space in this floating home?  The glass pavilion living area, the rooftop deck, or the cozy library?
