A practical look at the kinds of additions that pay off, what drives the timeline and budget, and how a full-service crew ties new space cleanly into the home you already have.
Sometimes you love your home and your lot — you just need more of it. An addition lets you add the exact space you're missing without giving up your location or starting over. Done well, it reads as part of the original house, not something bolted on. This guide walks through the options and the decisions so you can plan yours with clear eyes. When you're ready, our remodels & additions service handles the build.
If what you really need is separate space — a guest suite, a rental, or a workshop — a detached ADU, shop, or garage may pencil out better than attaching to the house. We're happy to help you compare.
Additions carry a wrinkle a new build doesn't: you're building onto a home someone already lives in, working around what's there, and sometimes finding surprises behind existing walls. The biggest cost and schedule drivers are:
For the same reasons a new home varies in cost, additions vary too. Our cost guide covers the factors that move a construction budget up or down.
Most homeowners stay in the house during an addition. We plan the sequence to keep your home livable as long as possible — building the new structure weather-tight before opening the connection between old and new, which we save for late in the process. Every project runs on Buildertrend with daily logs and photos, so you always know what's happening and what's next, and you get one dedicated liaison who answers.
We price additions on cost plus a fixed fee, locked to the agreed scope, so the number you plan around is the number that holds — no surprise change-order games. Every project is backed by a one-year workmanship warranty plus a longer structural warranty. Registered Idaho contractor, fully insured, 27+ years in Eastern Idaho.

Room additions, primary-suite and family-room additions, kitchen expansions, second stories, and bump-outs. Our in-house framing crew handles the structural tie-in to your existing home.
Often, yes — you keep your lot, your location, and much of your home, and add only the space you need. Whether it pencils out depends on how much you're adding and how it ties into the existing structure.
That's the goal. We match rooflines, materials, and finishes so a well-built addition reads as part of the original home rather than something bolted on.
We plan the sequence to keep your home livable as long as possible, opening the connection between old and new late in the process. Daily logs keep you informed the whole way.
