A Dwell-featured architectural gem by Jonathan Feldman, Shell Road is a custom-built Mill Valley retreat blending modern design with natural materials. Set on a private, sun-drenched lot, this 4-bed main home and matching guest casita offer warm wood interiors, soaring ceilings, radiant-heated concrete floors, and walls of glass that frame serene garden views. With vaulted bedrooms, a chef’s kitchen, library, media room, and a cedar sauna tucked into lush landscaping, this home captures the essence of Northern California living—thoughtful, timeless, and effortlessly cool.
