Situated on nearly one-half acre in one of Mill Valley's most coveted neighborhoods, 22 Ethel Avenue presents a truly uncommon opportunity to own a multi-structure compound in the heart of Marin County. Originally envisioned by architect Jean Noones as a modern interpretation of a historic firehouse campus, the property consists of a primary residence and a collection of detached structures thoughtfully positioned throughout the site. Connected by pathways, outdoor gathering spaces, and mature landscaping, the compound offers a sense of privacy, creativity, and possibility rarely found within walking distance of downtown Mill Valley. Set on approximately 20,473 square feet of land, the property provides an exceptional canvas for restoration, reinvention, or redevelopment. Whether envisioned as a multigenerational family compound, artist retreat, wellness campus, guest house collection, or legacy estate, the site's scale and configuration create opportunities that are increasingly rare in central Mill Valley. Surrounded by towering trees and nestled beneath the slopes of Mount Tamalpais, the property enjoys a remarkable combination of seclusion and convenience. Downtown Mill Valley, award-winning schools, renowned hiking and biking trails, and the cultural amenities that define Marin County are all moments away. Properties of this size, character, and location seldom become available. More than a residence, 22 Ethel Avenue represents an opportunity to steward a distinctive architectural vision while creating something entirely new for the future.
