High-performance desert retreat designed for sustainable living and timeless Southwest style.

Colored concrete floors, clerestory windows, and wood-clad casement windows fill the space with natural light. Interior finishes include diamond plaster walls, rounded corners, high pine ceilings, deep window sills, and BAUX acoustic soundboard construction. Modern systems feature grid-tied electric, efficient mini-splits with optional baseboard heat, and a Mastercraft standing seam metal roof. Set amid sweeping vistas of the Sky Island mountain ranges stretching toward Mexico, the property is beautifully hardscaped with mature blue agave—an authentic blend of architecture, landscape, and place.
