The Flagstaff Trail is just steps from the back door.Four levels rise through the home, each one a new perspective. The main level great room commands attention with soaring vaulted ceilings, exposed timber beams, walls of glass, and a sunken conversation and dining area at the heart of the home. The chef's kitchen features a Viking range, Thermador refrigerator, slate tile backsplash, skylight, custom cabinetry, and an island with sink. The primary suite offers a SW-facing Juliette deck, soaking tub, walk-in shower, and cedar closet.At the crown of the home, the 'birds nest' office delivers a work from home experience unlike anything else, with wraparound windows framing unobstructed snow-capped peaks and built-in seating perfect for inspired productivity or quiet reflection. Step down to the main level, where a wraparound deck extends the living space outdoors.Outside, a detached 1,500 square foot geothermal 4-season greenhouse makes year-round food production a reality. A fully owned solar array powers the entire home, making true off-grid living effortless. Gas fire pit, horseshoe pit, 2 fenced acres for dogs. 3-car garage plus covered carport. This is Boulder mountain living at its most extraordinary.
