Spring Valley is a refined yet welcoming modern retreat, designed for an active Boulder family seeking simplicity, balance, and connection to Colorado’s dramatic landscape. At 6,900 square feet, the home embraces the region’s awe-inspiring surroundings, large windows frame ever-changing views of the Flatirons, mountains, and Front Range, blurring the boundary between indoors and out.
The home’s unique upside-down organization situates the main living, dining, and kitchen spaces on the upper level, where natural light and sweeping vistas take center stage. From here, the primary suite and office extend onto an elevated courtyard, outfitted with a grill, firepit, and dining areas for entertaining. The lower level offers a complementary counterpoint: a sunken courtyard with spa, lounge seating, and lush concrete planters that create a secluded environment for quiet reflection. Between the two courtyards, the house offers spaces for both social gatherings and private retreat.
Interior spaces balance openness and intimacy. A wine room, sauna, and steam room bring elements of luxury, while a bright open stair and expansive glazing create an airy, uplifting atmosphere. A media room, recreation room, guest suite, and gym round out the lower level, while additional bedrooms and an office occupy the main floor.
The design is rooted in a restrained yet expressive palette of architectural concrete, blackened steel, plaster, and white oak. Exterior plaster walls appear as a light shell carved away to reveal darker inner layers of glass and steel, an interplay echoed inside where concrete and steel walls extend into living spaces and are softened by warm oak floors and cabinetry.
Sustainability was integral to the design. Triple-pane glazing with low solar heat gain coefficients, automated roller shades, and linear diffusers manage temperature fluctuations while preserving transparency. A pair of geothermal heat pumps power the HVAC system, offset by a rooftop photovoltaic array, minimizing the home’s carbon footprint. Even at the points where exterior concrete walls extend indoors, thermal breaks were carefully integrated to prevent energy loss and moisture issues.
Set on a compact flag lot adjacent to wetlands and a floodplain, the home’s three-level configuration makes efficient use of space while maximizing southern views. The result is a house that combines technical precision with experiential richness: a stylish, youthful, and sophisticated sanctuary that embodies understated modern living in Boulder.
