What Home Addition Work Involves

Room additions cover a wide range of projects that include everything from adding a single bedroom to major kitchen expansions. At their core, room additions require adding to your home's existing structure — either upward. This is distinct from remodeling, which stays inside the existing walls.

Because room additions involve multiple building disciplines, working with a general contractor who can coordinate each phase is essential.

Room additions are commonly chosen by homeowners who need more room but want to keep their current property. They're frequently selected for families welcoming new members. Whether it's a small bump-out or a full-scale addition, the process follows a clear set of phases that our builders have executed on hundreds of projects.
