Home Additions in Rigby
Whether it’s a primary suite, an attached garage with a bonus room, or pushing out a kitchen wall, an addition has to match the existing structure — foundation, framing, roofline, and finishes. Because we mill our own alder and walnut millwork in our Rigby shop, matching existing trim and cabinetry is something we do in-house, not something we sub out and hope for.
What an addition costs in Rigby comes down to four things: how much structure you are opening up, site access, how far the mechanical and electrical have to travel, and the finish level you want. A second story and a single-story bump-out are different projects with different cost stacks, so we scope yours to its own drawings instead of quoting off a per-foot menu. The kinds of additions we build here:
- Simple single-story addition
- Master suite — bedroom, bath and closet
- Kitchen bump-out with new cabinetry and counters
- Garage bay
- Second story
Why additions cost more per foot than new construction: Additions carry a different cost stack 15–25% higher per square foot than new construction because of demolition, structural tie-in to the existing home, and phased mechanical work (electrical, plumbing, HVAC) around a live-in family.
You get a line-item scope before you sign, so the number you approve is the number you pay.

Kitchens
Full kitchen remodels including custom cabinetry from our shop, counters, appliances, lighting, and layout changes. See our Rigby kitchen remodel guide for real 2026 numbers.
Master Baths
Master bathroom remodels get priced to their own scope — how much of the layout moves, custom cabinetry from our shop, the tile package and the finish level. Line-item scope before contract, no vague allowances.
Basements
Basement finishes with bedrooms, bathrooms, and egress windows that actually meet Idaho code — and add appraisable square footage to your home.
Whole-home renovations
Structural changes, layout reconfiguration, new mechanical, and full finish packages — managed like a custom build, with a schedule you can see every day.
Building outside of Rigby? Teton Valley and Jackson carry a different cost stack — higher land, longer site work, snow-load engineering and longer haul distances. Our Teton Valley custom home page covers how that market works.
