5425 96th Avenue SE

Mercer Island, WA 98040

Originally designed by Ralph Anderson, the pioneering father of Pacific Northwest architecture and a protégé of Frank Lloyd Wright, this exceptional residence reflects a philosophy that moves beyond rigid, box-like forms. Embracing an elongated, open, and nature-driven architectural language, the design creates a seamless visual and spatial flow between interior and exterior living. The L-shaped layout is thoughtfully integrated into the site, unfolding with elegance while maximizing panoramic views of Lake Washington, surrounding mountains, and serene woodland. Semi-enclosed courtyards and layered garden spaces draw from both Eastern and Western design traditions, creating ever-changing vistas and a sense of movement throughout the home. With virtually no visual dead ends, every space offers a carefully framed connection to nature. Renovated in 2022, the home preserves its original architectural integrity while incorporating contemporary design elements and modern comforts, perfectly suited to today’s lifestyle. 1/5 share 50’ beautiful, sunlit wade-in beach with designated moorage.
