Description

A striking blend of sustainability and sophistication; this home, designed by Annette and Dennis Martin in 2023, is tucked on a quiet cul-de-sac off one of Boulder's most coveted streets. This net-zero residence features advanced energy systems, including geothermal heating/cooling, radiant in-floor heat, a high-efficiency gas boiler and a 14.44kW solar array. A thoughtful layout connects open-concept living with vaulted ceilings, custom floating staircase, extensive millwork and designer lighting from Italy, Denmark, England, and the U.S. The main-floor primary suite offers a spa-like bath with onyx and white marble tile, double vanities, and a Kohler whirlpool tub. Entertain indoors or out with a chef's kitchen featuring Gaggenau and Sub-Zero appliances, a built-in Sedona grill, and a 10'x38' year-round saltwater pool. Expansive Sierra Pacific windows and doors frame views of the foothills while blending interior and exterior spaces. Savant smart home tech and Lutron lighting ensure effortless living at every turn.
