In the hardened foothills of the Franklin Mountains, on a lot overlooking downtown El Paso, architects Darci Hazelbaker and Dale Rush elevated a stoic, three-story home using the only material in sight: stone. The residence is supported by two lower levels that are composed of local basalt, a gesture toward the region’s rich geology as well as an abandoned quartz mine located near the top of the property. “We were trying to make a home that felt of the place, and El Paso is a very masonry-driven town,” explains Rush. The duo put their own twist on the local vernacular by quarrying a dark stone, instead of a more commonly used reddish-brown variety. The rough-hewn material blends into the landscape and creates a pedestal for the top-floor bedrooms, which are encased in white stucco walls. As a whole, the home reclines into the hillside, yet the highest box, which is designed to maximize views, hovers a few inches off the earth. The stone, Rush notes, keeps it grounded.
