What Room Additions Covers
Room additions cover a wide range of projects that involve everything from building an attached garage to major kitchen expansions. At their core, room additions involve expanding your home's existing structure — either outward. This is different than remodeling, which stays inside the existing walls.
These undertakings require a collaborative approach that involves architectural planning, building permits, foundation work, framing, electrical, plumbing, insulation, wall systems, and final finishes. Because room additions involve multiple building disciplines, choosing a general contractor who can oversee every step is critical.
Room additions are ideal for homeowners who need more room but prefer to stay in place. They're also a popular choice for homeowners planning to age in place. No matter the size, the work follows a clear set of stages that we have executed on hundreds of projects.
