Energy-Efficient Home Building in the Treasure Valley

Cost and timeline
Energy-efficient home cost in the Treasure Valley
Typical timeline
Schedule matches a comparable custom build at 10 to 14 months, plus roughly two weeks for envelope testing and commissioning before handover.
As of 2026, high-performance homes in the Treasure Valley plan between $275 and $425 per finished square foot excluding land. Our published planning-from figure of $575,000 reflects a smaller or simpler high-performance home; the envelope and mechanical upgrades that separate it from a code-minimum build typically add 3 to 8 percent on top of your base home cost, or about $20,000 to $55,000 on a mid-size home.
These are planning ranges, not bids. Part of the premium is recovered immediately through smaller heating and cooling equipment, and the rest through operating costs over the life of the home.

How it works
Our process, step by step
01
Performance target
We agree on an air-tightness and efficiency target up front, because it changes how the home is detailed.
02
Envelope design
Wall assemblies, window selection, and thermal bridge details drawn before framing, not decided on site.
03
Verified construction
Mid-build blower-door test while the air barrier is still accessible and inexpensive to correct.
04
Commissioning
Final blower-door and duct-leakage testing, ventilation balancing, and documented results.

Why design-build for your energy-efficient homes
As a design-build home builder, we bring architectural design, engineering, estimating, permitting, and construction under one contract and one accountable team. That removes the handoffs and finger-pointing that happen when the architect, the plan reviewer, and the general contractor all answer to someone different - and it keeps your energy-efficient homes on a single, coordinated schedule.
You get a written, fixed price before we break ground and a published draw schedule through the build.
