200 Mountain King Road

Welcome to 200 Mountain King Road in Lagunitas, California. Set on twenty acres in West Marin and accessed via a gated private road, the property comprises a clean, contemporary stucco-and-glass residence and accompanying guest house with a double garage, designed by Jeremy Kotas, a protge of Frank Gehry. The natural landscape by Bernard Trainor features purple needle grass, yarrow, lupins, and poppies, along with manzanita, madrone, coastal live oak, and a century-old bay tree. The grounds extend to the edge of parkland, with sweeping views of surrounding ridgelines, including Mount Tamalpais. Hiking and biking trails begin just beyond the front gate. The home's generous living spaces are defined by natural light and expansive views. Soaring ceilings and walls of glass frame the landscape, while the living and dining areas offer both everyday comfort and effortless entertaining. The open kitchen features Poggenpohl cabinetry and a full suite of Gaggenau appliances, including double ovens, cooktop, extractor, and dishwasher, complemented by a Sub-Zero refrigerator and wine cooler, ample storage, and a sleek powder room. Living areas open to a terrace with broad concrete steps set into the meadow, leading to a heated 25-yard pool and spa. The pool's clean geometry reflects sky and cloud, contrasting beautifully with the rolling hills and coastal fog. The primary suite opens to a tranquil courtyard with a reflecting pool and includes tall ceilings, expansive glass, a private office, spa-like bath with soaking tub and Boffi fixtures, and a walk-in closet. A guest bedroom with en-suite bath and garden views completes the main house. Walnut floors, wool carpeting in bedrooms, radiant heating, and automated window coverings run throughout. The guest house offers a flexible two-level layout with soaring ceilings, kitchenette, full bath, loft, and private patioideal for guests or workspace. Additional features include irrigated gardens, sculptures by Jefferson Mack, a solar system, full fencing, and a security system. Though private and secluded, the property is minutes from Fairfax and approximately 45 minutes from the Golden Gate Bridge.
