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 heart, room additions require adding to your home's existing structure — either horizontally or vertically. This is not the same as remodeling, which stays inside the current square footage.
These undertakings call for a coordinated effort that involves architectural planning, permit acquisition, foundation work, structural carpentry, electrical, plumbing, insulation, interior finishing, and cosmetic detailing. Because room additions touch so many systems, choosing a general contractor who can manage all of it is critical.
Room additions are commonly chosen by homeowners who have outgrown their current layout but aren't ready to move. They're frequently selected for families welcoming new members. Regardless of the scope, the work follows a structured set of phases that we have refined over many years.
