What Home Addition Work Entails
Room additions encompass many different types of construction that span everything from adding a single bedroom to major kitchen expansions. At their foundation, room additions involve expanding your home's existing structure — either upward. This is not the same as remodeling, which stays inside the current square footage.
These projects call for a collaborative approach that involves architectural planning, building permits, foundation work, framing, electrical, plumbing, insulation, interior finishing, and cosmetic detailing.
