About this property

Have you ever wanted to live in a treehouse? Here’s your chance. Perched above the wooded greenery of historic Colman Park on a quiet, private dead-end drive, this 1916 Craftsman offers a rare sense of seclusion while keeping downtown Seattle less than 15 minutes away and I-90 just five minutes from home. A nearby park path takes you through the greenery to the water, making the setting as walkable as it is peaceful. Inside, 2,285 square feet across three levels pairs original character with an easy, practical layout, including hardwood floors, coved ceilings, built-ins, a wood-burning fireplace, dining room, and walk-in pantry. Three bedrooms and 1.75 baths include an upper-level primary suite with its own bath and walk-in closet. The 479-square-foot basement, finished in 2018, adds valuable flexibility as a fourth bedroom or family room, plus a separate finished space for storage, hobbies, or a workshop. A large, secure crawl space provides even more storage. The sellers tackled the big-ticket improvements with new windows and deck in 2016, a new roof in 2024, and a new combination boiler in 2026. Skylights bring in additional natural light, the detached carport provides covered parking, and the 3,870-square-foot wooded lot enjoys partial territorial views with remarkably few nearby neighbors. It is a distinctive combination of character, flexible space, substantial improvements, and peaceful in-city convenience.
