Room Additions in Tampa Bay

A room addition adds permanent, permitted square footage to your existing home — commonly a master suite, in-law suite, family room, sunroom, or second story. Merit Contracting handles the full process: design coordination, structural engineering, permitting through the county building department, foundation and framing, roofing tie-in, electrical, plumbing, HVAC extension, drywall, finishes, and final inspection.
