There are homes with views. Then there is 5097 Flagstaff Road.Perched above Boulder at the end of a private dead-end drive, this one-of-a-kind octagon-shaped residence sits on 10.25 forested acres just minutes from downtown Boulder yet completely removed from it. No neighbors in sight. No noise but wind and birds. And a horizon that stops people in their tracks: Longs Peak and the Indian Peaks Wilderness to the west, Boulder's city lights glittering far below to the east. The Flagstaff Trail begins 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, and walls of glass framing the ridge. A sunken conversation and dining area anchors the heart of the space. The chef's kitchen is outfitted with a Viking range, Thermador refrigerator, slate tile backsplash, skylight, and custom cabinetry. The primary suite opens to a SW-facing Juliette deck and includes a soaking tub, walk-in shower, and cedar closet.At the crown of the home, the Birdsnest office is in a category of its own. Wraparound windows frame unobstructed snow-capped peaks in every direction, and the kind of focused quiet that remote work was meant to look like. Step down to the main level and a wraparound deck extends the living space into the trees.Outside, a detached 1,500 sq ft geothermal greenhouse makes year-round food production a reality regardless of season. A fully owned solar array powers the entire home, delivering true energy independence with none of the compromise. A gas fire pit, horseshoe pit, and 2 fenced acres make this a property that lives as well outside as in. 3-car garage plus covered carport.This is what it looks like when Boulder mountain living is done without limits.
