Designer Treehouse | Panoramic Bay Views | Cedar Hot Tub | Steps to Mount Tam Trails 
Wake up above the clouds in a designer treehouse overlooking the Bay. Panoramic views, cedar hot tub, redwood privacy, vaulted ceilings, a marble soaking tub with sunset views, expansive decks, and direct access to Mount Tam trails create a rare warm sunny Marin living experience just 20 minutes from San Francisco.
Perched in the treetops on picturesque Christmas Tree Hill in Corte Madera, surrounded by towering redwoods on one side and opening to panoramic 180 degree Bay views on the other, the home captures sweeping vistas of the Richmond Bridge, Bay Bridge, and Alcatraz. Enjoy luminous sunrises and rolling morning fog drifting over the Marin hills from nearly every room.
