What Home Addition Work Entails
Room additions are a broad category that include everything from constructing a new bathroom to major kitchen expansions. At their core, room additions involve expanding your home's footprint — either horizontally or vertically. This is not the same as remodeling, which stays inside the existing walls.
These builds require a coordinated effort that involves architectural planning, permit acquisition, foundation work, rough construction, electrical, plumbing, insulation, drywall, and cosmetic detailing.
