Exceptional Mill Valley Home

Offered for the first time – An Iconic Mid-Century Modern Retreat in downtown Mill Valley on over ½ acre of land.

Tucked away at the end of a cul-de-sac, 27 Throckmorton Lane presents a once-in-a-lifetime opportunity: a dramatic, exquisitely preserved mid-century modern residence sited on an 1/2 acre of lush, private grounds with breathtaking views of Mount Tamalpais. Built in 1969 and on the market for the first time, this architectural gem offers a rare blend of privacy, scale, and timeless design, just moments from the heart of town.

Anchored by soaring ceilings, exposed timber beams, and glass walls, the home seamlessly dissolves the boundaries between indoors and out.

The main level is designed for grand living and effortless entertaining, featuring a chef’s kitchen with an oversized breakfast room, an elegant formal dining area, and a warm, inviting living room that spills out onto a sprawling deck one way and manicured gardens and patios the other way.

The luxurious primary suite is a true sanctuary, boasting a spacious walk-in closet and a flexible built-in lounge, private office, or nursery area. These two areas have built-in dressers, a desk, and cabinets.  The large primary bath has direct private access to the yard and a conveniently located hot tub.

A dramatic half bath completes this floor.

Upstairs, a mezzanine lounge showcases sweeping views and architectural drama, flanked by two generous bedrooms and a beautifully appointed full bath.

On the lower level, a cozy family/media room, two additional bedrooms, and a full bath provide flexible living options for guests or multi-generational living—the entry foyer offers multi-directional options and a large laundry room with folding countertop, storage, and sink.

Outside, the property unfolds like a private botanical garden: mature Japanese maples, specimen flower beds, multiple flagstone and aggregate patios, stone benches, a heritage rose garden, vegetable beds, and a dedicated sports court. Central to the spacious backyard is a stone waterfall and pond surrounded by greenery, flowers, and Dwarf Red Japanese Maple. Every corner invites exploration and reflection. A detached two-car garage and a separate attached walk-in storage area complete the estate.

Offering the ultimate balance of seclusion and convenience, this singular property feels worlds away yet places boutique shopping, cafés, schools, and world-class trails at your doorstep.
