What Room Additions Covers

Room additions cover a wide range of projects that span everything from constructing a new bathroom to major kitchen expansions. At their foundation, room additions involve expanding your home's current floor plan — either horizontally or vertically. This is distinct from remodeling, which room additions works within the current square footage.

These builds require a collaborative approach that combines architectural planning, building permits, foundation work, structural carpentry, electrical, plumbing, insulation, wall systems, and flooring and trim. Because room additions touch so many systems, choosing a experienced builder who can manage all of it is essential.
