A rare opportunity to own a home that stands as a true testament to modern green design & sustainable building practices. Few homes in Colorado can boast such an impressive array of accolades, including Best Custom Home under 5,000 sq. ft. in Colorado (2019), the AIA Colorado Award of Merit in Sustainable Design (2022), and Bronze at the International Design Awards (2023). In fact, it has the designation of LEED Platinum certification-the highest awarded by the U.S. Green BuildingCouncil. This passive-solar home is thoughtfully situated on .7 acres to embrace its breathtaking surroundings, offering sweeping views of the Flatirons. Its design maximizes sunlight in the winter while minimizing heat gain in the summer. The roof features a 10kw solar system, complemented by a geothermal heat pump, a boiler and advanced foam insulation-all working in harmony to optimize energy efficiency. These enhancements contribute to the home's near net-zero energy rating, a HERS score of 18.The ground floor seamlessly blends indoor and outdoor living, creating an open, airy space for relaxation & entertainment. The upper level opens up to a "living roof" and soaring ceilings with floor to ceiling glass, offering panoramic views of the Flatirons. Three spacious bedrooms and a large, light-filled family room form the heart of the home. Enjoy Where You Live!

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
