Welcome to 630 Northstar Court, where architecture becomes sculpture and living becomes an artistic experience. Designed by Charles Haertling, Colorado's most celebrated modernist architect, this is not just a home - it's a rare, livable work of art. Virtually no other Haertling home has undergone a renovation of this caliber, with such a deep reverence for the original design while also maintaining a remarkably livable, open and functional floor plan that is also artful yet practical, supporting comfort, flow, and purpose. Originally built in 1976, this sculptural residence, shaped like twin cones, resembling a cassette tape in plan and a double teepee in elevation, is one of Haertling's most iconic creations. Each tower is anchored by a sculptural, wood-burning fireplace, defining elements that ground the soaring geometry with drama and purpose. Set against the backdrop of the foothills, the home offers remarkable Flatiron views, sitting like a sculpture in the landscape and blending geometry, nature, and light. Framed by walls of glass and grounded in organic materials, the home flows into a serene meditation room, a tranquil water feature, and a secluded private hot tub. Outdoor living is elevated with over 1,600 sq ft of decks and patios. Perhaps one of Boulder's best-kept secret enclaves with its coveted location directly across from the private community pool, pickleball/tennis and volleyball courts, and a mere 300-foot walk to access trails with the most jaw-dropping panoramic views of the Flatirons and Foothills, and only 1 mile to Lucky's Supermarket, beloved restaurants, and cafes, easily accessible from scenic bike paths. With downtown Pearl St Mall only 2.5 miles, you will enjoy an unmatched blend of peace, artistry, and convenience. Sustainable upgrades include a 4.5kW solar PV system, EV charger, in-floor radiant heat & 2 mini-splits for cooling & additional heating.
