Modern custom home in one of Reno's most prestigious areas, Mountain House is well sited to maximize unobstructed views of Mount Rose and Slide Mountain. This four bedroom plus office, three bath home sits on a full acre just outside the gates of Montreaux. The grounds have a circular drive and paved access to the 672 sf insulated workshop with vehicle door, upgraded power, and mini-split heating and cooling. There is paved and gravel pads for RVs, boats, or offstreet parking and there is no HOA. You may think an almost 3,000 sf home might suffer from high utility bills, but the passive solar design elements offset winter heating bills, and the paid off 8kW photovoltaic array supports all the AC you could want. Water-smart native landscaping reduces water usage. The layout of this unique home offers multi-generational flexibility, supplemental income from a separate-entrance (and previously approved) STR, or ample living and entertaining spaces. The first floor (daylight basement) has one bedroom and an office, large living room with stunning river rock wood stove surround, full bathroom, and kitchenette and separate access. The office could be used as a 5th bedroom, gym, home office or media room. The second (entry) level has two bedrooms, an ADA accessible bathroom, a towering cathedral ceiling, and cozy gas fireplace with slate surround. There is also a sun room for plants, pets, or relaxation. Soak in the Sierra sunsets from the large second-level deck, reinforced for a hot tub. The top floor is entirely composed of the primary suite with unbeatable mountain and territorial views. The one acre lot backs to HOA land greatly reducing the chance of rear neighbors, and has recently undergone fire smart defensible space maintenance across Zones 0 - 3 (report available) completed by CalFire certified wildfire risk reduction specialists.
