What Home Addition Work Entails

Room additions cover a wide range of projects that span everything from constructing a new bathroom to major kitchen expansions. At their foundation, room additions require adding to your home's current floor plan — either upward. This is different than remodeling, which reconfigures the existing walls.

These undertakings require a coordinated effort that brings together architectural planning, permit acquisition, foundation work, structural carpentry, electrical, plumbing, insulation, interior finishing, and final finishes. Because room additions involve multiple building disciplines, hiring a general contractor who can oversee every step is essential.

Room additions are ideal for homeowners who need more room but aren't ready to move. They're often the right move for multigenerational households. No matter the size, the work follows a structured set of steps that our builders have executed on hundreds of projects.
