SPECTACULAR - Located 15 minutes from Boulder and Golden and just 25 minutes to Denver, CLOUD NINE is a mid-century modern inspired architectural marvel. Set into a mountainside, a commanding pedestal supports a cantilevered upper level that rises above the surrounding forest. Wall to wall and floor to ceiling windows provide panoramic views extending from the monumental Fountain and Lyons rock formations out to the eastern plains.
The upper level great room seamlessly connects an entry foyer with elevator access, monolithic gourmet kitchen, formal living, dining, and media spaces wrapped around a central stairwell with display cabinetry. The stairwell descends alongside a 21ft tall sunlit atrium to a private middle level including a sanctuary master bedroom with a hanging deck, two spacious secondary bedrooms, laundry, cozy mezzanine library, elevator and an adjacent dog/play yard. All bedrooms have expansive sloped windows with stunning views. Continuing down to the modern industrial lower level, which introduces the home's steel and concrete structure, there is a fabulous two-story atrium/gallery/game space with an unexpected sloped wall featuring modern gilt paneling and a large sheltered patio for epic outdoor entertaining. This level also has a sprawling flex area suitable for exercise, office and studio, a finished utility room, an extra-large storage room and a generous sequestered guest suite with ensuite bath and private patio. All rooms have expansive stunning views.
Additional features include in-floor and in-ceiling radiant heating and cooling, an oversized 3+ vehicle garage with oversized doors, RV storage and workshop. Street level parking, walkout patios, and a 3-story elevator provide easy ADA access to the entire home. This home is a rare find - a foothills gem with south facing, street level access -NO steep ice-covered driveway or entry!
