From First Conversation to Move-In Day
Step 1
Consultation (Week 1)
We learn your budget range and how you want to live. You leave with a clear picture of what your project involves and what it costs — not a vague promise to follow up with a quote.
Step 2
Design (Weeks 2–4)
Custom floor plan developed to your spec. 3D renderings before anything moves forward. Revisions happen here, not on the job site.
Step 3
Permitting (Weeks 4–6)
We deliver permit-ready plans. Your contractor handles submission and approval with your local building department.
Step 4
Site Prep & Foundation (Weeks 6–9)
Your contractor prepares the site, installs the foundation, and runs utilities.
Step 5
Shell Construction (Weeks 10–14)
Frame, siding, roofing, windows, and doors. The exterior goes up fast — typically two to four weeks once the foundation is ready.
Step 6
Interior Finish (Weeks 14–36+)
HVAC, plumbing, electrical, insulation, drywall, flooring, cabinetry, fixtures. Timeline varies by scope and finish level.
Typical total timeline: 6–10 months from consultation to move-in.

Popular Starting Points — All Fully Customizable
30×50 — 1,500 sq ft
Right-sized for couples, retirees, or vacation properties. Two bedrooms, one to two bathrooms, open living area. Lower material costs make higher-end finishes more accessible at this footprint.
40×60 — 2,400 sq ft
The most requested size. Three bedrooms, two bathrooms, open kitchen and great room, two-car garage or workshop. Clear-span design with no interior load-bearing columns. The sweet spot for cost, livability, and resale.
60×60 — 3,600 sq ft
Full family home with dedicated workspace. Four bedrooms, three bathrooms, home office, attached three-bay garage or shop.
60×80 — 4,800 sq ft
Generous living with estate-scale space. Four to five bedrooms, multiple living zones, large shop, room for guest suite or in-law quarters.
30×80 — Shop-Plus-Living
Half workshop, half home. Dedicated bay for equipment, boats, RVs, or livestock with full living quarters on the same footprint. The most popular configuration for rural working properties.
Custom sizes available for any footprint. We engineer to your dimensions, not the other way around.
Turnkey Idaho Barndominium Builders & Prices
Idaho’s mountains drive cost through snow load: roofs engineered for heavy ground snow, drift, and sliding snow mean a stouter structure than a flatland build. Turnkey builds here run about $190–$260 per square foot of heated, finished living space. Higher-tier labor and materials and deep frost footings round out the number. The bigger lever on your total is how much you condition: unconditioned shop space runs roughly $75–$105/sq ft and covered porch $55–$80, well under the living rate. On a 60×60 (3,600 sq ft), that split is the whole spread — a shop-forward build lands around $420K–$585K, a home-forward one $585K–$805K, same footprint and same county. A steel shell kit alone starts near $28/sq ft. What yours costs comes down to footprint, living-to-shop ratio, and finish level — which the first consultation pins down.
