What Home Addition Work Involves
Room additions cover a wide range of projects that involve everything from building an attached garage to major kitchen expansions. At their core, room additions require adding to your home's current floor plan — either outward. This is not the same as remodeling, which works within the existing walls.
These projects require a full range of trades that brings together architectural planning, building permits, foundation work, structural carpentry, electrical, plumbing, insulation, interior finishing, and cosmetic detailing. Because room additions require so many interconnected trades, working with a general contractor who can oversee every step is the key to a smooth project.
