Why choose us
Why homeowners choose us
- 01
Measurably lower heating and cooling costs for the life of the home
- 02
Even temperatures and no cold rooms in January
- 03
Blower-door and duct-leakage testing, so performance is verified
- 04
Better sound isolation and filtered air as a side effect of a tight envelope
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.
Planning details
Typical timeline
Schedule matches a comparable custom build at 10 to 14 months, plus roughly two weeks for envelope testing and commissioning before handover.
Local details
Local notes
For energy-efficient homes in Star, confirm the property jurisdiction and scope before applying. City addresses and unincorporated county parcels may use different building departments. Confirm required building and trade permits, inspections and review times for the actual address.
Energy-Efficient Homes cost in Star
Planning ranges for Star match the broader Treasure Valley market. 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.
Energy-Efficient Homes across Star
We build throughout Star, including Star River Ranch, Star Crossing. Lot conditions, utility access, and subdivision design standards vary between these areas, so we tailor the site plan, foundation, and elevations to the specific parcel rather than dropping a plan onto it.
As a local team familiar with Star landmarks like Boise River, Star Riverwalk Park, Freedom Park, we understand how the area is developing and plan energy-efficient homes that fits the neighborhood and holds its value.
New construction permits and plan review in Star
Permits inside Star city limits come from the City of Star Building Department. Addresses outside city limits go through the county instead; we check this for you at the first visit.

Our Star designs also account for the local semi-arid climate with hot summers and cool winters, from insulation and ventilation choices to frost depth, snow load, and materials that hold up to Treasure Valley freeze-thaw cycles.

Frequently asked questions
Star budgets track the wider Treasure Valley picture. High-performance homes valleywide plan in 2026 at roughly $275 to $425 for every finished square foot, land excluded. Schedule a walk of your site and we'll prepare an itemized budget for it.
The test pressurizes the home and measures air leakage through the envelope. It turns air-tightness into a number, not a claim. We run it during construction, while leaks are cheap to fix, and again at completion.
No, you don't. Panels are usually the wrong first dollar. Cutting demand with the envelope and the mechanical systems saves energy at a lower cost per unit. Start with a tight house, then consider generation if you want it.
Yes. Star sees our crews year-round, as does outlying Ada County, and an efficient home goes through Star's plan review and impact fees just like any other house.
Lead with the estimator on our site, which gives a planning range, and follow it with a free planning consultation; bring any efficiency goals. For a lot you're weighing, we'll go see it with you and explain what its site costs will depend on.
Cold enough to plan for. At the Boise Air Terminal, the nearest long-term NOAA station, the 1991–2020 normals show average December lows near 25°F and about 17.6 inches of snow a year. A tight, well-insulated envelope keeps heating costs in check through that season.
