Overview

Updated 3 weeks ago

5097 Flagstaff Road sits at the end of a private dead-end drive on 10.25 forested acres, an octagon built up through four levels. The road below is one of the best-known climbs in Colorado cycling, and Green Mountain Trail starts steps from the back door. Downtown Boulder is minutes away and you would never guess it. Longs Peak and the Indian Peaks Wilderness hold the view west, and after dark Boulder spreads out far below to the east. Inside, vaulted ceilings, exposed timber beams, and walls of glass in the great room pull the ridge indoors. A sunken conversation and dining area anchors the center. The kitchen is built for people who love to cook and includes a Viking range, Thermador refrigerator, slate tile backsplash, and custom cabinetry. Also on this level, secondary bedrooms, and an updated full bath give guests their own corner of the house. Downstairs, the family room has a fireplace and a full bar with a saltwater fish tank. The primary suite has a level to itself and opens to a southwest-facing Juliette deck. At the top, the Birdsnest office is ringed in glass with forest and mountains in every direction. Outside, a detached 1,500 square foot geothermal greenhouse means tomatoes in February and greens all winter. A fully owned solar array powers the property. There is a gas fire pit for evenings, horseshoes set up below the house, and two fenced acres around it. Ride Flagstaff before work, hike Green Mountain at lunch, and watch the sun drop behind the Divide from the deck.
