New bedroom, office, or in-law suite additions
Custom home expansions and room additions built by a licensed remodeling contractor who plans for the long term. We design additions that match your home’s structure and style from the start.
Growing families, home offices, and multigenerational households all need more room sooner or later. Rather than pushing a move across the Treasure Valley, a well-built addition lets you stay in the neighborhood you already know, near the schools, parks, and routes you rely on every day.

Room additions involve more moving parts than most remodeling services, including permits, structural engineering, and matching new construction to an older home.
Room additions are one of the biggest investments a homeowner can make in a house, so the contractor matters as much as the design. Here is what sets our approach apart from other remodeling contractors in the area.
A room addition solves the space problem without the cost and disruption of buying a new home.
We build room additions and home expansions for homeowners throughout Boise and the surrounding Treasure Valley communities. Wherever your home sits in our service area, our remodeling company brings the same licensed craftsmanship and clear communication to the job.
