Perched above the Roaring Fork River, this three-level mountain contemporary residence is a study in chic, light-filled living. A comprehensive 2020 remodel transformed the home's two primary living levels with a designer's eye, and its defining gesture is the glass: expansive new floor-to-ceiling windows set with sleek, low-profile mullions that all but dissolve the wall between interior and mountainside. The effect is quietly spectacular, drawing Aspen Mountain and the river light straight into the living spaces. Extending across more than 5,700 square feet, the residence enjoys one of Aspen's most walkable settings, moments from downtown, Herron Park, the Rio Grande Trail, and the Smuggler hiking and biking trails. The main level, fully remodeled, rises to soaring ceilings and opens to a living room anchored by a fireplace and a sleek custom kitchen. A dining area flows into a side TV den with custom built-ins and a bar, served by a full bathroom, while a functional mudroom keeps mountain life effortless. Glass doors open directly onto an expansive patio and a rare, grassy level-yard plateau that overlooks the river as it flows past Herron Park. The top floor is devoted to a fully remodeled primary suite, a serene retreat with spectacular river and mountain views and the gentle sound of the water below. A fireplace and a private balcony set the tone, while a striking new contemporary bath brings double vanities, a separate makeup area, and thoughtfully designed, beautifully lit his-and-hers closets. An adjoining office completes the level. The walk-out lower level offers three en suite guest bedrooms, three baths, a laundry room, an additional office, and a second living area. Remodeled in 2012 with a warmer, more classic mountain contemporary sensibility, it creates natural separation between the home's private and shared spaces. A self-contained one-bedroom, one-bathroom accessory dwelling unit, entered through its own private side entrance, adds versatile square footage suited to a guest suite, home office, or private retreat. Outdoors, the residence lives as gracefully as it does within. Expansive patio and terrace for lounging and entertaining open to the rare, grassy sanctuary above the river, a genuine luxury in the mountains. Completed by a two-car garage and framed by the sound and light of the Roaring Fork, the home offers a seldom-found combination of privacy, ease, and true walk-to-town convenience in one of Aspen's most coveted riverside settings.
