What Home Addition Work Covers
Room additions are a broad category that involve everything from building an attached garage to large-scale family room builds. At their core, room additions involve expanding your home's current floor plan — either horizontally or vertically. This is not the same as remodeling, which stays inside the original layout.
These builds require a full range of trades that involves architectural planning, building permits, foundation work, framing, electrical, plumbing, insulation, drywall, and final finishes. Because room additions require so many interconnected trades, working with a general contractor who can manage all of it is essential.
Room additions are commonly chosen by homeowners who want a dedicated space but prefer to stay in place. They're often the right move for multigenerational households. Regardless of the scope, the work follows a clear set of phases that our builders have refined over many years.
