What Home Addition Work Covers
Room additions encompass many different types of construction that involve everything from adding a single bedroom to major kitchen expansions. At their heart, room additions involve expanding your home's current floor plan — either outward. This is different than remodeling, which works within the existing walls.
These projects call for a coordinated effort that involves architectural planning, building permits, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions involve multiple building disciplines, choosing a general contractor who can manage all of it is critical.
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 homeowners planning to age in place. Whether it's a small bump-out or a full-scale addition, the process follows a clear set of stages that our team have mastered through experience.
