What Home Addition Work Covers
Room additions cover a wide range of projects that span everything from constructing a new bathroom to full second-story additions. At their core, room additions mean physically extending your home's existing structure — either outward. This is distinct from remodeling, which stays inside the existing walls.
These builds call for a coordinated effort that brings together architectural planning, permit acquisition, foundation work, structural carpentry, electrical, plumbing, insulation, interior finishing, and final finishes. Because room additions touch so many systems, hiring a general contractor who can coordinate each phase is the key to a smooth project.
