What Room Additions Covers
Room additions are a broad category that involve everything from building an attached garage to large-scale family room builds. At their heart, room additions involve expanding your home's footprint — either upward. This is distinct from remodeling, which reconfigures the current square footage.

Because room additions require so many interconnected trades, working with a experienced builder who can manage all of it is essential.
