What This Type of Project Entails
Room additions encompass many different types of construction that include everything from adding a single bedroom to full second-story additions. At their foundation, room additions involve expanding your home's current floor plan — either outward. This is different than remodeling, which reconfigures the existing walls.
These undertakings call for a coordinated effort that involves architectural planning, building permits, foundation work, framing, electrical, plumbing, insulation, drywall, and cosmetic detailing. Because room additions involve multiple building disciplines, choosing a skilled construction team who can manage all of it is critical.
Room additions are ideal for 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. Regardless of the scope, the process follows a structured set of stages that our builders have mastered through experience.
