My Notes

A+ location and virtually new construction! Just steps from downtown Mill Valley's amenities, renowned architect Heidi Richardson has re-imagined this 4BR/4BA grand Throckmorton residence for the ultimate modern lifestyle. A major rebuild and expansion, including new foundation, was completed in September 2015. An emotional property with magazine-worthy design, this is classic Mill Valley re-invented for today's inspired living. The functional flexible floor plan offers ideal flow between light-filled, grand scale living spaces. Exquisite architectural details include custom millwork, pocket doors, box beam ceiling, and white oak floors. Opening to the great room, the kitchen features Carrara marble, top-of-the-line cabinetry, and appliances by SubZero, Wolf, and Bosch. Luxurious baths have Carrara marble and handmade Italian tile, Toto Lloyd toilets, and high-end fixtures. This state-of-the-art home offers amenities like all new systems, high efficiency multi-zone furnace, tankless/recirculating water heater, LED lighting, an alarm system, and wiring for A/V and data. The garage includes a dedicated line for charging electric vehicles.Enjoy indoor-outdoor living, with a family room opening to the newly landscaped bluestone patio, lawn, and inviting fire pit area. A gas line has even been set up for a barbeque. This sunny property occupies a coveted, rarely-available location, near the library and award-winning Old Mill Elementary School.
