What This Type of Project Covers
Room additions are a broad category that include everything from building an attached garage to full second-story additions. At their core, room additions mean physically extending your home's existing structure — either outward. This is distinct from remodeling, which works within 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 final finishes.
