What This Type of Project Entails
Room additions cover a wide range of projects that involve everything from constructing a new bathroom to large-scale family room builds. At their foundation, room additions require adding to your home's existing structure — either upward. This is distinct from remodeling, which stays inside the current square footage.
These projects demand a collaborative approach that involves architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, drywall, and final finishes. Because room additions require so many interconnected trades, hiring a experienced builder who can coordinate each phase is essential.
