What Room Additions Covers
Room additions are a broad category that include everything from constructing a new bathroom to large-scale family room builds. At their foundation, room additions mean physically extending your home's current floor plan — either upward. This is distinct from remodeling, which reconfigures the original layout.
These builds call for a collaborative approach that involves architectural planning, permit acquisition, foundation work, framing, electrical, plumbing, insulation, drywall, and final finishes. Because room additions involve multiple building disciplines, working with a general contractor who can oversee every step is essential.
Room additions are commonly chosen by homeowners who have outgrown their current layout but prefer to stay in place. They're often the right move for homeowners planning to age in place. No matter the size, the process follows a clear set of phases that our team have executed on hundreds of projects.
