Built to last on 10 level acres with panoramic San Francisco Peaks views, no HOA, and room for horses. Designed as a passive-solar home, it uses the sun, the home's orientation, windows, and thermal mass to collect, store, and distribute heat. A south-facing greenhouse with skylights, south windows, and attic vents gathers warmth, and Trombe-style block walls store it and move air through the house. Open or close the vents to bring greenhouse warmth inside in winter or help keep things cool in summer, and adjust the two end skylights by hand to fine-tune the temperature, all helping lower heating and cooling costs. Inside, vaulted ceilings, skylights, and a gas fireplace anchor the open living and dining area, and the kitchen offers a gas range and walk-in pantry. A main-level primary suite with a bath plumbed for a tub is joined by a bonus room, loft, den, and space for another bedroom. Solid construction throughout: 2x6 framing, heavy-duty beams placed for future upstairs additions,...
