Whether you're ready to build a new bedroom, a larger kitchen, or a dedicated workspace, room additions are the answer.

What This Type of Project Covers
Room additions are a broad category that include everything from building an attached garage to large-scale family room builds. At their foundation, room additions involve expanding your home's footprint — either outward. This is not the same as remodeling, which works within the existing walls.
These undertakings call for a full range of trades that brings together architectural planning, city approvals, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions involve multiple building disciplines, working with a skilled construction team who can manage all of it is the key to a smooth project.
Room additions are commonly chosen by homeowners who want a dedicated space but want to keep their current property. They're also a popular choice for multigenerational households. Whether it's a small bump-out or a full-scale addition, the work follows a structured set of phases that our team have executed on hundreds of projects.
