Inside a Hillside Contemporary in Mill Valley

On 1.45 acres at the base of Mount Tamalpais, just north of San Francisco and the iconic Golden Gate Bridge, this unprecedented five-bedroom residence—the result of years of dedication on the part of Quezada Architecture and a team of designers, engineers, and contractors—was built in 2014 and has been lovingly maintained by its sole owners. Composed of classic contemporary lines formed from oxidized steel, cedar, glass, and metal, it seems to jut forth, a dramatic extension of the land that surrounds it.

Professional landscaping—consisting of an array of native drought-tolerant plants—creates a stylish introduction. Within is a serene setting where walls of glass offer views from nearly every room. The core of the main level are public spaces—dining room, kitchen, and living room—with an open floor plan that is fluid and light flooded. Steps away is an office with built-in desk space for two, shelves, and drawers. Throughout, fixtures are of the finest quality, the organic palette is soothingly minimalist, and walls and lighting are ideal for the display of art.

Atop the walnut-and-steel staircase is a versatile loft space, which can serve as an office, a family room, or a fitness area and opens to a cool, shady patio alcove facing into the hillside. The master bedroom enjoys a view of treetops and blue sky through disappearing wall of glass. Its en suite bath is illuminated from above by a skylight and includes a “wet room” with a striking soaking tub and an open shower. The suite also includes an impeccably outfitted walk-in closet and dressing room. Just beyond are two guest bedrooms—one featuring a built-in window seat, cabinets, and bookshelves of crafted from smooth, warm wood—sharing a sleekly stylish bath with dual sinks. An enviable third-floor terrace with covered and open-air spaces and a fireplace feels enveloped by greenery.

Located on the entry level is an oenophile’s dream, a wine room that is both functional and artful, with a unique display behind sliding glass doors. Secluded on a level beneath the most removed of the four guest bedrooms is the streamlined media room, and the home’s two car garage is tucked below. Across the motor court lies a self-sufficient 745-square-foot guesthouse with a private terrace and an open floor plan that includes a full kitchen, a living and dining area, and a semi-secluded bedroom area. The bath features dual sinks and a spacious step-in shower.

Paired with a pool deck featuring an outdoor kitchen and grilling area as well as space for lounging and dining, the alluring 50-foot swimming pool and spa exists in harmony with the surrounding native greenery. Above the deck is a refreshing swath of emerald no-mow lawn. Rooftop solar panels contribute to the estate’s exceptional energy efficiency, for which it has been GreenPoint rated. Perfect for wandering, the remarkably private property is home to groves of mature sycamore and redwood trees and abundant wildlife, including deer, foxes, owls, and red-tailed hawks.

The thriving community of Mill Valley—with its popular shops and restaurants—is minutes away. Also nearby are acres of delightful protected open space ideal for hiking and mountain biking
