Selected residential energy systems shaped around operating requirements, site constraints, and coordinated delivery.
"Timberline Independence" serves a fully off-grid, 20,000-square-foot mountain residence. The operating requirement was clear: maintain dependable whole-home power without a utility connection while supporting the electrical demands of a large luxury property through changing weather and seasonal solar conditions.
"Shadowline" supports a modern luxury residence built into the hillside near the base of Shadow Mountain. The home is organized as two architectural wings connected by a long central structure, with extensive glazing, flat rooflines, landscaped terraces, and a lower outdoor living area overlooking the valley.
"Highlands Hearth" serves a substantial three-level residence near Aspen Highlands. The property has a more traditional mountain character than many contemporary Aspen homes, with warm wood finishes, sloped rooflines, and a lower-level garage integrated into the site.
