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.

Energy-Efficient Homes cost in Garden City
Planning ranges for Garden City 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 Garden City
We build throughout Garden City, tailoring the site plan, foundation design, and elevations to the specific parcel rather than dropping a plan onto it.
As a local team, we plan energy-efficient homes that fits the neighborhood and holds its value.
New construction permits and plan review in Ada County
New home construction in Garden City requires a building permit, plan review, and impact fees through Ada County. Residential plan review commonly runs 3 to 6 weeks, and parcels outside municipal service need septic approval through Central District Health and a well permit through the Idaho Department of Water Resources. We build those timelines into your schedule from day one and handle submissions, fees, and inspections as part of the contract.
Our Garden City designs account for the local Treasure Valley climate, including frost depth, snow load, insulation levels, and durable exterior materials.
