The Tower House: A 1970 Hand-Built Stinson Beach Masterwork Just Hit the Market

Most houses are built. The Tower House in Stinson Beach was made — hand-built in 1970 by Valentino Agnoli, a local architect and artist who was part of West Marin's creative community in that era, and owned by only two people in the 55 years since. It has just listed for $2,395,000, and the listing description alone is worth your time.

What Agnoli Built

Tucked into a hillside grove of redwoods, laurels, and pines — with a waterfall audible from outside and ocean waves not far beyond — the Tower House spirals upward through three stories in Agnoli's signature style: a nautical-ladder sequence of connected spaces that minimizes disturbance to the land while offering a rare 365-degree perspective of the natural world around it. Over 70 glass windows move light through the structure all day, bending it softly against warm redwood and fir timbers. The upper floor sits under a handcrafted wood lattice ceiling and holds the main living space, a cooking area with gas range, a built-in dining nook, a loft above a walk-in closet, and a writer's desk alcove with a casement window. The two sleeping en-suites occupy the middle and lower floors, each with peek-a-boo ocean views and their own shower rooms. Outside, a deck staircase leads to a separate art studio and bunkhouse with a sleeping loft — a structure that reflects the same intention as the main house: every space purposeful, nothing wasted.

The Place It Belongs To

The Tower House sits on 0.41 acres in Stinson Beach, the small Marin County community at the edge of Mount Tamalpais State Park and the Golden Gate National Recreation Area. From the doorstep, the Dipsea and Matt Davis trails are minutes away on foot — trails that connect Stinson Beach to Mill Valley through some of the most beautiful terrain in Northern California. The town itself is walkable: beach, cafes, and the familiar rhythm of a place that has always attracted artists, architects, and people who understand the difference between a vacation and a life. At 709 square feet across three stories, the Tower House is not a large home. It is a precise one — a place, as the listing puts it, where life slows and one is allowed to pause. It belongs to a lineage of West Coast architecture that honors the land it occupies, and it has done so, quietly, for 55 years.
