W8 UPDATE / 28 May 2013
Joseph Vigil’s Ghost House is included on the “Home Sweet [Energy Efficient] Home: A Sampling of Denver’s Sustainable Residential Projects” Tour during the AIA National Convention in Denver this Summer.
by V Brandy LeMae, managing partner
The Ghost House is perched on a slope of Green Mountain, backing onto open space which in turn backs onto State and National Forest. The lot is a rectangular ½ acre that is only large enough to accommodate the modest (2,200 SF) structure and a very long driveway.
The East face of Green Mountain is high plains-foothill transition in elevation extremely dry with high desert vegetation. The home has a small footprint with low water plants and grasses immediately around the house that quickly transitions to the native species. Areas disrupted by construction are once again self sustaining.
The barrier free upper floor provides convenience for the home owners and accessibility for the future. The lower floor provides multi use spaces that can function as offices, private space, and bedrooms.
