A Resilient, Multi-generational Mountain Retreat that Meets Extreme Alpine Conditions<\/h3>\r\n

S<\/span>et high within the exposed terrain of Powder Mountain Ski Resort, a ski-in\/ski-out mountain residence by Sparano + Mooney Architecture<\/a> merges Japanese-inspired design thinking with the demands of extreme alpine conditions. Conceived as a long-term, multi-generational retreat, the home balances sculptural form, environmental resilience, and adaptability across life stages.<\/p>\r\n\r\n

Due to its remote location, the home is run completely off of propane, and heated by highly-efficient radiant heat throughout.

The conceptual foundation draws from kirigami\u2014the Japanese art of cutting and folding paper\u2014translated into architectural expression through folded planes, layered thresholds, and a dynamic exterior skin. This influence reflects the clients\u2019 deep appreciation for Japanese culture and design, which guided both the spatial logic and material restraint of the project.<\/p>\r\n\r\n

Inside, the house embraces a clean, modern aesthetic shaped by careful curation rather than minimalism alone. Interiors are designed to accommodate visitors of all ages, including aging family members, with universal access embedded into the circulation strategy. From the garage, occupants enter a corridor housing an elevator that connects all levels, enabling aging in place while supporting multi-generational living without compromise.<\/p>\r\n\r\n

Desiring a clean, modern aesthetic, the interior design of the home and its art were chosen with this aesthetic in mind, leading to an eclectic yet curated space.

Sustainability and self-sufficiency were central to the project, particularly given its remote, high-elevation setting. The home operates entirely on propane and relies on highly efficient radiant heating throughout. Southern fa\u00e7ades are protected by overhangs to manage solar gain, while operable windows positioned strategically throughout the house provide natural cooling and ventilation during warmer months.<\/p>\r\n\r\n

Kitchen amenities include Thermador and Wolf appliances, a recessed induction cooktop in the main kitchen, panel-ready and built-in Sub-Zero refrigerator, and gas cooktop in the scullery, with designated space for smaller countertop appliances.

The residence unfolds across multiple levels, including a primary suite positioned five feet above the main floor. This upper-level retreat features a private deck and steam shower and can be fully separated from the rest of the home, offering privacy and flexibility. Public spaces emphasize indoor\u2013outdoor connection: the dining room opens directly to a courtyard via a multi-slide door system, while the main kitchen remains visually unobstructed, free of overhead cabinetry or ceiling-mounted fixtures. A secondary scullery kitchen, equipped with a built-in bar, supports entertaining and is located adjacent to the media room.<\/p>\r\n\r\n

Material choices reinforce both durability and sensory experience. Hem fir dominates the interior finishes, paired with rift white oak cabinetry, black granite countertops, and polished concrete floors. In contrast, the onsen-inspired bathing area introduces cedar\u2014selected for its aroma and warmth\u2014and stone tile flooring, creating a tactile retreat within the home.<\/p>\r\n\r\n

The facade\u2019s exterior cladding is made from TEKK\u014d™ steel, which the team selected for its ability to bend and fold around the home\u2019s upper level and throughout the courtyard, with standing seams that then turn into the corners.

The stark mountain landscape surrounding the site informed a broader architectural tension between movement and permanence. This is most evident in the exterior cladding system, where custom bent-metal TEKK\u014d™ steel wraps the structure in a combination of solid and perforated panels. The steel\u2019s ability to bend and fold allows it to articulate corners, upper levels, and courtyard edges seamlessly, while its corrosion-resistant steel\u2013zinc composition ensures longevity in harsh alpine conditions.<\/p>\r\n\r\n

Environmental performance was addressed through both form and envelope. The building is oriented to minimize disruption to the native landscape while maximizing opportunities for interaction with nature. Designed to endure annual snowfall averaging 225 inches, wind speeds of up to 110 mph, and heavy snow loads, the structure incorporates robust insulation strategies throughout. Walls achieve R-38 insulation, while the roof assembly reaches R-70. A white PVC roof with a high Solar Reflectance Index further enhances energy efficiency.<\/p>\r\n\r\n

High-performance glazing and continuous exterior insulation contribute to a tightly sealed envelope, while backup energy systems\u2014including two Tesla Powerwall units\u2014provide resilience during power outages. The home also includes an electric vehicle charging station, reflecting a forward-looking approach to mobility. Kitchen specifications align with the home\u2019s understated luxury, featuring appliances from Thermador, Wolf, and Sub-Zero, along with high-performance windows and doors by Marvin. Together, these elements support a home that is as functional as it is refined.<\/p>\r\n

Ultimately, the project demonstrates how cultural reference, environmental responsibility, and architectural precision can converge in a residence designed not only for its setting, but for longevity\u2014both ecological and human.<\/p>\r\n
