What This Type of Project Covers
Room additions are a broad category that involve everything from building an attached garage to full second-story additions. At their heart, room additions require adding to your home's existing structure — either upward. This is distinct from remodeling, which stays inside the existing walls.
These projects demand a full range of trades that involves architectural planning, building permits, foundation work, structural carpentry, electrical, plumbing, insulation, wall systems, and final finishes. Because room additions involve multiple building disciplines, choosing a general contractor who can manage all of it is the key to a smooth project.
