This 10,000 square foot luxury custom home proves that green building techniques can be applied to any size building. Carved into the side of the mountain, this Tuscan-style villa follows the terrain of the landscape. Built to Boulder County’s strict fire resistant standards, the exterior was completed by a master stone mason and capped with a rusted corrugated steel roof.

Travertine, venetian plaster, custom metal railings, Colorado buff flagstone, and custom mahogany bifold doors make for a dramatic entryway. Master stone masonry work and custom woodwork continue through the kitchen and living spaces, creating a seamless transition between indoors and out.

This green home is heated and cooled with Geo Thermal mechanical systems. Forced air cooling and heated radiant slabs. It also has a ground mounted 10kW photovoltaic array solar power system.
