What This Type of Project Covers

Room additions encompass many different types of construction that involve everything from constructing a new bathroom to major kitchen expansions. At their foundation, room additions mean physically extending your home's current floor plan — either upward. This is distinct from remodeling, which reconfigures the original layout.

These builds demand a full range of trades that involves architectural planning, permit acquisition, foundation work, framing, electrical, plumbing, insulation, drywall, and flooring and trim.
