What This Type of Project Entails
Room additions cover a wide range of projects that include everything from building an attached garage to large-scale family room builds. At their foundation, room additions require adding to your home's current floor plan — either outward. This is distinct from remodeling, which works within the existing walls.
These builds demand a full range of trades that brings together architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, interior finishing, and flooring and trim.
