What Room Additions Entails
Room additions cover a wide range of projects that span everything from building an attached garage to large-scale family room builds. At their foundation, room additions involve expanding your home's current floor plan — either outward. This is distinct from remodeling, which works within the existing walls.
These builds demand a full range of trades that involves architectural planning, building permits, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and final finishes. Because room additions require so many interconnected trades, choosing a skilled construction team who can coordinate each phase is essential.
Room additions are a great fit for homeowners who want a dedicated space but prefer to stay in place. They're frequently selected for multigenerational households. Regardless of the scope, the process follows a structured set of phases that our builders have refined over many years.
