Cost and timeline

Semi-custom home cost in the Treasure Valley

Typical timeline

Most semi-custom homes run 7 to 10 months total: 6 to 10 weeks for plan adaptation and permitting, then 6 to 8 months of construction.

As of 2026, semi-custom homes in the Treasure Valley plan between $225 and $300 per finished square foot excluding land. Our published planning-from figure of $425,000 reflects the simplest plans; a common 2,000 square foot home lands between $450,000 and $600,000. The savings against a fully custom build come from design and engineering work that is already complete, not from cheaper construction.

These are planning ranges, not bids. Lot conditions, plan modifications, and finish level move the number, which we confirm with a line-item budget once a plan and lot are matched.

How it works

Our process, step by step

01

Plan and lot match

We walk your lot and identify which base plans actually fit the setbacks, slope, and views.

02

Adaptation and pricing

Structural and layout changes are drawn and priced against a fixed base, so you see what each change costs.

03

Selections

You choose from finish packages with real allowance figures rather than open-ended placeholders.

04

Build and handover

Construction on a published schedule, then inspections, walkthrough, and warranty documents.

Why design-build for your semi-custom homes

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 semi-custom homes on a single, coordinated schedule.

You get a line-item budget with written allowances before we break ground and a published draw schedule through the build.

Common questions

Frequently asked questions

Semi-custom homes generally plan between $225 and $300 per finished square foot in 2026, excluding land, with our simplest plans starting near $425,000. A common 2,000 square foot home lands between $450,000 and $600,000.

Semi-custom starts from an existing engineered plan and modifies it. Fully custom starts from a blank page. Semi-custom is faster and the budget band is narrower; fully custom gives you complete control over layout and massing.

Finishes, cabinetry, elevations, and non-structural walls are straightforward. Moving load-bearing walls, changing the roof structure, or altering the foundation footprint triggers re-engineering, and at that point a custom design is often the better value.

No. The framing, envelope, mechanical systems, and workmanship standards are identical. The difference is how much of the design work has already been done.

Sometimes, with a daylight basement or a revised foundation. We check this during the lot match step, because forcing an unsuitable plan onto a difficult site erases the cost advantage that made it appealing.

Typically 7 to 10 months from contract to move-in, compared with 10 to 14 months for a fully custom home of similar size.
