Our process,
step by step
Planning consultation
We talk through your lot, your program, and a realistic budget band before anyone draws anything.
Feasibility and site review
Soils, utilities, access, setbacks, and slope get checked so the design suits the ground it sits on.
Design and fixed scope
Drawings, selections, and a line-item budget are locked together before we submit for permit.
Build and handover
Weekly updates through construction, then testing, walkthrough, and your warranty documents.
Typical timeline
Plan on 10 to 14 months end to end: roughly 3 to 5 months for design, engineering, and permitting, then 7 to 10 months of construction depending on size and site complexity.
Custom home building cost in the Treasure Valley
As of 2026, most Treasure Valley custom homes plan between $250 and $400 per finished square foot excluding land, which puts a 2,400 square foot home between $600,000 and $960,000. Simpler single-level designs on flat valley lots can come in near $225 per square foot, while foothills sites, steep grades, and highly detailed interiors regularly exceed $450.
These are planning ranges, not bids. Lot conditions, home size, roof and wall complexity, and finish level drive the final number, which we confirm with a line-item budget after a lot walkthrough.
Custom Home Building across the Treasure Valley
We provide custom home building services throughout the Treasure Valley, with dedicated local pages for each city we serve. Lot availability, permit paths, impact fees, and HOA design review differ between Ada and Canyon County communities, so each city page covers the details that matter where you plan to build.

Why design-build for your custom home building
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 custom home building on a single, coordinated schedule.
You get a written scope and a fixed price before we break ground, clear allowances for every selection, a published draw schedule, weekly progress updates through the build, and a one-year workmanship warranty after you take possession.
