Passive House Prefab Homes Built for Colorado

Phoenix Haus builds precision-crafted, Passive House-certified prefab homes designed specifically for Colorado's mountain and high-desert climate. Whether you're building in the Rockies, the Western Slope, or the Front Range — we know how Colorado's terrain, altitude, and extreme weather demand more from a home. Our homes are built to give you exactly that.

Why Colorado Needs a Different Kind of Home

Colorado homes face serious stress. Subzero winters, intense summer heat, high altitude UV, wildfire smoke, and fast-shifting weather patterns all wear down conventional construction faster than builders admit. Standard builds keep HVAC companies busy. Phoenix Haus homes keep energy bills low and indoor air clean — year-round.

Our Passive House standard means:

✓ R-50 wall insulation and R-70 roof insulation

✓ Triple-pane windows and doors that seal tight against mountain cold

✓ Continuous fresh-air ventilation with heat recovery — so you're never breathing recycled, stale, or smoke-tainted air

✓ Airtight construction tested and certified to Passive House Institute (PHI) standards

The result: a home that holds its temperature, breathes clean air, and costs a fraction of a conventional home to run — for decades

Colorado Projects We're Proud Of

  • Basalt, CO — Old Town Custom Home

    A couple in their 80s needed a main residence plus a fully equipped guest suite — in one of Old Town Basalt's most space-constrained lots. Phoenix Haus panels went up in under a week. The 2,000 sq ft project exceeded energy performance expectations and impressed even the architect next door.

  • Built to Belong

    Ridgeway, CO — Passive House Ranch Home
    A three-generation ranch family didn't build a home for themselves — they built one for the people who take care of their land. Designed entirely by the client using Phoenix Haus' building system, this Passive House-standard home in Ridgeway, Colorado was built for a working family, not a weekend guest. From a crane nearly lost to 60mph gusts on day one to occupancy in six months, this is what it looks like when a home is built to last — for the land, the people, and the generations after them.

  • From City Chaos to Mountain Clarity

    Fairplay, CO — Prefab Mountain Home
    A California-to-Denver family spent four years trying to escape the city and build a home at 11,000 feet in Fairplay, Colorado — without compromising on quality or values. Between wetland permits that took three years, 280 psf snow loads, and a six-month build window, most builders would have walked. Phoenix Haus didn't. When outside engineering miscalculated snow loads mid-design, they absorbed the full redesign cost — no change orders, no finger pointing. The result is a Passive House home built to breathe clean air and outlast generations in one of Colorado's most unforgiving environments.

Colorado Building Codes — We Handle It

Colorado is raising the bar on energy performance, and Phoenix Haus homes are already above it.

2024 Colorado Model Low Energy and Carbon Code (MLECC)

✓ The state's new minimum energy benchmark takes effect as municipalities update their codes. Our homes meet and exceed it — by design, not retrofit.

✓ Denver Passive House Pathway

✓ Denver adopted Passive House certification as an alternative code compliance pathway in 2022.

✓ Phoenix Haus homes qualify. No workarounds needed.

ADU-Ready

Colorado's House Bill 24-1152 streamlined ADU permitting across the state — one ADU is now allowed on most single-family lots. Our H2 and H5 series models include ADU configurations, and our team understands Colorado's size, setback, and design requirements.
