What Home Addition Work Covers
Room additions are a broad category that include everything from building an attached garage to full second-story additions. At their core, room additions involve expanding your home's existing structure — either horizontally or vertically. This is distinct from remodeling, which works within the current square footage.
These undertakings demand a coordinated effort that combines architectural planning, permit acquisition, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and cosmetic detailing. Because room additions involve multiple building disciplines, hiring a experienced builder who can manage all of it is essential.
