It's 4pm Friday. You close your laptop, head north over the Golden Gate, and in about an hour you're turning onto a private gated drive. The city is already a memory. This is 200 Mountain King Road twenty acres in West Marin designed by Jeremy Kotas, a protege of Frank Gehry, with landscape by Bernard Trainor. Native grasses, manzanita, and a century-old bay tree blend seamlessly into the surrounding state park. Mt. Tamalpais on the horizon. Hiking and biking trails from your front gate. Inside: soaring ceilings, walls of glass, and views that shift with the light. The kitchen is appointed with Poggenpohl cabinetry, Gaggenau appliances, and Sub-Zero refrigerator and wine cooler. Wide concrete steps drop through the meadow to a heated 25-yard lap pool that holds the sky like a mirror while fog creeps in from the coast. The primary suite opens onto a private courtyard with reflecting pool. Deep soaking tub, natural stone, Boffi fixtures, walnut hardwood floors, radiant heat, and automated blinds. A study/office can be closed off from the main living area. Guests have their own world a two-level guest house with soaring ceilings, kitchenette, sleeping loft, and a patio with views. Private enough that everyone gets the weekend they wanted. Above the house, a deck beneath mature oaks catches the western light at day's end. Vegetable gardens, landscape sculptures by Jefferson Mack, 48-panel solar system, and whole-property security. Recent well and septic reports available. Sunday evening you're back in the city in no time. Or don't leave at all.
