No. Planning ranges on this site are starting points, not bids. A written scope and proposal follow a site visit and a lot review. Request a quote and we reply within one business day. Design-build means one accountable team handles architectural design, engineering, Ada and Canyon County permitting, and construction under a single contract, backed by a written line-item scope before the foundation is poured.

Land, well and septic, driveway beyond the apron, landscaping, window coverings, and appliances sit outside the planning number unless your written scope says otherwise. Site costs such as utility runs and grading are listed on their own lines so they do not hide inside a square-foot figure.

Deposit and draw timing are set in your construction contract and aligned with your lender's schedule. Most clients use a construction-to-permanent loan that funds the build in stages called draws. We provide the budgets, plans, and draw documentation lenders ask for, and we schedule inspections to line up with those milestones so financing does not stall the build.

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 roughly between $600,000 and $960,000. Simpler single-level designs on flat valley lots can approach $225 per square foot, while foothills sites, steep grades, and highly detailed interiors regularly exceed $450. Land, site work, and utility connections are separate and vary more between lots than the house itself does, which is why we price them as their own lines rather than folding them into a square-foot number.

You get a line-item budget before we break ground, not a price per square foot that changes once the foundation is in. We set allowances for flooring, cabinetry, plumbing, and lighting at what those things genuinely cost here, so an allowance is not a hidden overage waiting to surface. We work as a true design-build firm, meaning design, engineering, permitting, and construction sit under one contract with one project manager, and we send a written update every Friday rather than waiting for you to call. Any change during construction requires a written change order with a price and a schedule impact before the work happens.

No. Roughly half the people we talk to are still looking. If you already own a lot or have one under contract, we can start with a feasibility review of that specific parcel. If you are still searching, we can evaluate a lot before you make an offer and tell you what the site work will realistically cost, which is the part most buyers underestimate. A cheap parcel that needs a well, a septic system, three hundred feet of driveway, and significant grading is often more expensive overall than a serviced lot that costs more up front.

A custom home starts from a blank page: the plan is drawn for your family and your specific lot. A semi-custom home starts from an existing plan we adapt, changing finishes, room configurations, and elevations without redrawing the structure from scratch. Semi-custom is typically faster to permit and less expensive because the engineering and design work is largely done, and it suits people who find a layout they like and want to personalize rather than originate it. Custom makes sense when the lot is unusual or your requirements do not map onto an existing plan.

Plan on 10 to 16 months from first consultation to move-in for most custom homes. That usually breaks down as two to four months of design and selections, one to three months for permitting through Ada or Canyon County, and seven to eleven months of construction. Semi-custom homes on an existing plan are often two to four months faster because the design and engineering are largely complete. Winter slows foundation and flatwork in Idaho rather than stopping the job, and we build those weather windows into the schedule rather than discovering them later.

Most clients use a construction-to-permanent loan, which funds the build in stages called draws and then converts to a standard mortgage at completion. We provide the budgets, plans, and draw documentation lenders ask for during underwriting, and we schedule inspections to line up with your draw milestones so financing does not stall the build. We are not a lender and do not originate loans, but we work with your bank throughout rather than leaving you to translate between the two.
