Like in many places across the U.S., the real estate market is booming in Aspen, Colorado. And, as companies move in to replenish the dwindling housing inventory, one real estate developer hopes to provide a more sustainable alternative to the inevitable onslaught of cookie-cutter homes. Working in collaboration with San Francisco-based Aidlin Darling Design, the developer has completed a solar-powered dwelling that serves as a new energy-efficient prototype for speculative real estate in Aspen. Located on the steep slopes of Red Mountain, the Aspen Residence boasts spectacular panoramic views that overlook Aspen to the west and an undeveloped landscape to the south.
