What Home Addition Work Covers

Room additions are a broad category that include everything from building an attached garage to major kitchen expansions. At their foundation, room additions require adding to your home's existing structure — either horizontally or vertically. This is different than remodeling, which reconfigures the current square footage.

These builds demand a collaborative approach that involves architectural planning, building permits, foundation work, structural carpentry, electrical, plumbing, insulation, interior finishing, and final finishes.
