A thoroughly modern house inspired by craftsman houses of the early twentieth century.  The house features an open floor plan and large expanses of glass, and is sited to allow major interior spaces  to take advantage of views of the Flatirons to the southwest, the foothills to the west, and a large pond and water feature constructed on the property.  A palette of natural materials, including limestone, stucco, fir timbering and trim, and slate roof with copper flashings, impart a stately quality and ensure that this house will last for generations.  This 9000 SF house is  completely heated and cooled by a state of the art geothermal system, with photovoltaic collectors supplying the electricity to operate the system.
