601 East Cooper Avenue is among downtown Aspen’s most celebrated addresses, a striking architect-designed tower that brought a new standard of modernist living to one of Aspen’s most beloved neighborhoods. The penthouse residence crowns the building with a dramatic full-floor layout and a wraparound private terrace that captures views of Aspen Mountain, the valley, and the quietly romantic streets below. The all-glass façade renders the living spaces in a continuous wash of natural light, while the interiors offer a refined backdrop of white lacquer, stone, and glass. The primary suite is positioned to capture sunrise views over the mountains, and the open living and dining areas are among the most gracious in downtown Aspen.
