Home Additions in Utah County

The right addition gives your family the space it needs without leaving the home and neighborhood you love. Summit Construction designs and builds high-end additions across Utah County that look and feel like part of the original home.

Additions that fit your home

As home addition builders in Utah County, we focus on larger, high-end additions: expanding living space, building for a growing family, and integrating the new work so it reads as part of the original home. This is not handyman or small-repair work.

What we handle

Large-scale addition projects, planned and built end to end.

Large-scale home expansions

Whole-home expansion projects, not small repairs or handyman work.

Second-story and main-floor additions

Adding a second story or expanding on the main floor, planned end to end.

Design integration

New work designed to match your existing home, not stand out from it.

Structural and permitting planning

Both structural work and permits are built into our process.
