What This Type of Project Covers
Room additions are a broad category that span everything from constructing a new bathroom to major kitchen expansions. At their heart, room additions require adding to your home's current floor plan — either upward. This is distinct from remodeling, which stays inside the current square footage.
These projects require a full range of trades that brings together architectural planning, permit acquisition, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and flooring and trim.
