3903 48th Avenue S

A former Seattle Times/AIA “House of the Month,” this Martin Henry Kaplan–designed residence is a sophisticated and enduring expression of modern architecture. The crown jewel: a dramatic rooftop deck with sweeping views of Lake Washington and the Cascades. Expansive windows carry those vistas into every room, flooding the interiors with natural light. Arranged across three levels, the home offers a double garage and generous storage at street level, open living and entertaining spaces on the main floor, and private bedroom quarters above. Outdoor decks extend from each level, reinforcing a seamless connection between the interiors and the surrounding landscape. The main floor is designed for living and entertaining in equal measure: a spacious eat-in kitchen, inviting family room, two fireplaces, and flexible dining and living areas, all anchored by custom built-ins and Kaplan’s signature detailing. Upstairs, the primary suite offers panoramic lake and mountain views, a spa-like bath, two large walk-in closets, and direct access to a private deck. Two additional bedrooms and a full bath complete the level. Just steps from the water—lakeside parks, kayaking, paddleboarding, and open-water swimming. Lake Washington living at its best.
