At the top of the hill, on an extraordinary 60,000 sqft site with panoramic views of the canyon and rolling hills, sits this architectural estate designed in 2007 by Barbara Bestor. Two buildings are positioned side by side, forming an entrance promenade and an open patio between them. The main house, spanning 3,951 sqft, features expansive double-height spaces and an open floor plan. It is only partially divided by a series of walls that define the primary bedroom and bathroom, as well as a loft with several office/bedroom spaces and an additional guest suite with its own kitchen. All rooms on the main level have direct access to the outdoors with private garden areas. The main living area, including the kitchen and dining, shares a double fireplace with the adjacent primary bedroom. Both face a pool that runs the length of the house and overlooks the canyon. A 12-foot-deep shaded porch creates a transitional space between indoors and outdoors, ideal for lounging and embracing a daytime outdoor lifestyle. The guesthouse, or "Moon Suite" (769 sqft), is a fully independent unit with a bedroom, bathroom, kitchen area, and living room - all oriented towards the view. At the rear of the structure, there is also a large studio with storage space that could be used as a 3-4 car garage. The owners' desire for a sustainable home led to the use of structural steel trusses and a custom-adapted prefabricated system, allowing for wide spans and open spaces. Passive temperature control supports year-round heating and cooling (now supplemented by additional AC units), while large custom windows are coated with a low-emissivity transparent metallic film. The white metal facade reflects light, reducing heat gain. The house features very high ceilings inspired by vernacular agrarian shed structures and includes solar panels, radiant heating, and a variety of peach, pear, and olive trees on the property. This special retreat offers multiple living and working possibilities. It is on the market for the first time and represents one of the few sustainable designs by Barbara Bestor ever available for sale.
