About this home

This remodeled 3+ bedroom 1900s home lies in the heart of Gerstle Park and is truly a piece of San Francisco in Marin. Offering convenient single-level living with a flexible floor plan, the home blends classic architectural charm and period details with thoughtful modern updates.

The updated kitchen marries timeless design with everyday functionality, flowing seamlessly into the dining space and out to one of two decks, ideal for al fresco entertaining. The front room off the living area doubles as a bedroom with a built-in office nook or serves as a family room for additional gathering space. The primary suite features backyard access, ample closet space, and a spa-inspired ensuite bath with double vanity and walk-in shower. A large lower level provides additional flexible space perfect for a home gym, play area, or wine storage. The garage includes laundry, generous storage, plus a full bathroom with shower.
