Discover a rare mid-century modern gem tucked into the sun-drenched hills of Middle Ridge. Built in 1956 and cherished by its original owner, this timeless Post-and-Beam residence brings the best of classic California modernism to one of Mill Valley’s most coveted enclaves.

Set on over an acre of private, south-facing land, the home is defined by its dramatic walls of glass, clean architectural lines, and an effortless connection to nature. Light pours into every room, framing views of the surrounding canyon, heritage redwoods, and the serenity of the ridge beyond.

The home spans approximately 2,464 square feet and offers three spacious bedrooms, a dedicated home office, and generous open-concept living areas anchored by exposed beams and original mid-century details. Nearly every space opens to the outdoors, creating a seamless indoor-outdoor lifestyle that feels both intimate and expansive.

A huge sunny deck invites gatherings, quiet mornings, and sunset dinners, while the level yard—rare for the area—adds even more usable outdoor living space. The two-car garage and ample storage complete the home’s practical comforts.

Perfectly private yet moments to Mill Valley’s vibrant town center and world-class trailheads, 500 Ralston Avenue is a once-in-a-generation opportunity to own a true architectural original in an extraordinary natural setting. This is mid-century Mill Valley at its purest: simple, soulful, sunlit, and designed for the way we want to live today.
