What Home Addition Work Covers

Room additions are a broad category that include everything from adding a single bedroom to major kitchen expansions. At their heart, room additions require adding to your home's existing structure — either upward. This is different than remodeling, which stays inside the current square footage.

These builds require a collaborative approach that brings together architectural planning, building permits, foundation work, framing, electrical, plumbing, insulation, interior finishing, and cosmetic detailing.
