Custom Homes Designed and Built for Your Boise Lot

We design and build custom homes in Boise for people who already have a lot, or are about to buy one. Our design work and the construction plan stay with the same team, so the house is drawn for your site and for the way it will actually be built.

What does a Boise custom home cost?

Every project is priced to its scope. Lot conditions, size, design complexity and finish level all move the number, and on a Boise lot so do slope, utilities and which office reviews the permit. We build the budget alongside the design, and you get clear budget updates as drawings and selections take shape, so you can see how each decision affects cost before work starts in the field.

Start with the lot, not the floor plan

Boise lots vary more than most buyers expect. A North End infill lot asks for a tight footprint and careful window placement next to close neighbors. A foothill lot brings slope, soils and driveway grade into every design choice. A parcel at the edge of town may sit in unincorporated Ada County and rely on a well and septic. We look at those conditions first, then draw the home around them. Building just outside Boise? See our pages for Meridian home builders and the Eagle luxury home builder path for foothill lots.

City of Boise or Ada County?

A Boise mailing address does not settle who issues your permit. Parcels inside city limits go through City of Boise Planning and Development Services. Unincorporated parcels go through Ada County Development Services. Hillside lots inside the city may also fall under Boise's Hillside Development Overlay, which adds engineering such as a soils report and a stamped grading and drainage plan. Confirming jurisdiction early keeps the design and schedule honest. Our guide to building in the Boise Foothills covers sloped lots in more depth.

Design-build in Boise

Design-build means one team carries the home from first sketch to final walkthrough. In Boise that matters most when the site is hard: the people drawing the foundation talk to the people pouring it, and budget questions come up while the plan can still change. See our design and build services for everything one team covers.

Timeline in weeks

Most custom homes take about 9 to 17 weeks for design and permit preparation and about 35 to 60 weeks for construction. Hillside engineering and permit review can add time. Our custom home timeline guide breaks down each phase.

Real Project Journals

We do not show photos of homes we did not build, and we are not featuring a completed Boise home on this page. These current project journals show how we run a job:

  • Eagle custom home addition. A design-build addition in Eagle. The journal follows footing excavation, the footing inspection, a revised footing detail from the structural engineer that the crew formed before the pour, foundation wall sleeves and hold-downs set before concrete, backfill and under-slab plumbing prep. Read the Eagle custom home addition journal.
  • Garden Valley Retreat. A second-home custom cabin in Garden Valley. The journal covers setting the footprint and septic location on site, a short pier delay after washout instead of pouring on washed-out ground, floor framing, trusses, an approved rough-in inspection and final grading. Read the Garden Valley Retreat journal.

Questions Boise Custom Home Clients Ask

What should I ask a Boise builder before I hire them?

Ask who designs the home, who builds it and how the two talk. Ask how they handle your specific lot, whether it is infill, foothill or acreage, and how they confirm permit jurisdiction. Ask to see real project records, not just finished photos.

Do you build on lots in the Boise Foothills?

Yes, when the project fits our design-build scope. Foothill lots usually need a survey, a soils report and engineered foundation and grading plans, so we bring those in early.

Does the City of Boise or Ada County issue my permit?

It depends on the parcel. Lots inside city limits go through the City of Boise. Unincorporated lots go through Ada County Development Services. We confirm this before design starts.

How long does a custom home in Boise take?

Most homes take about 9 to 17 weeks for design and permit preparation and about 35 to 60 weeks for construction. Complex hillside sites take longer.

How is a Boise custom home priced?

Every project is priced to its scope. We build the budget alongside the design and give you clear budget updates as drawings and selections develop.

Do you offer design as well as construction in Boise?

Yes. Design and construction run under one design-build process. Our Boise architectural design page explains who leads design and how it compares to hiring a licensed architect.
