What This Type of Project Entails
Room additions encompass many different types of construction that involve everything from constructing a new bathroom to full second-story additions. At their core, room additions mean physically extending your home's existing structure — either outward. This is not the same as remodeling, which stays inside the current square footage.
These builds demand a full range of trades that involves architectural planning, building permits, foundation work, framing, electrical, plumbing, insulation, interior finishing, and cosmetic detailing.
