What This Type of Project Involves

Room additions are a broad category that include everything from constructing a new bathroom to large-scale family room builds. At their heart, room additions mean physically extending your home's current floor plan — either upward. This is different than remodeling, which reconfigures the current square footage.

These undertakings demand a collaborative approach that brings together architectural planning, permit acquisition, foundation work, framing, electrical, plumbing, insulation, wall systems, and cosmetic detailing. Because room additions touch so many systems, hiring a experienced builder who can manage all of it is essential.
