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 heart, room additions mean physically extending your home's current floor plan — either upward. This is not the same as remodeling, which reconfigures the existing walls.
These builds call for a coordinated effort that involves architectural planning, permit acquisition, foundation work, structural carpentry, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions involve multiple building disciplines, working with a general contractor who can oversee every step is critical.
Room additions are a great fit for homeowners who need more room but want to keep their current property. They're often the right move for families welcoming new members. Regardless of the scope, the process follows a clear set of phases that our builders have refined over many years.
