What This Type of Project Covers
Room additions are a broad category that include everything from constructing a new bathroom to major kitchen expansions. At their heart, room additions mean physically extending your home's current floor plan — either outward. This is not the same as remodeling, which reconfigures the existing walls.
These undertakings demand a full range of trades that brings together architectural planning, building permits, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and flooring and trim.
