What Home Addition Work Involves
Room additions are a broad category that involve 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 upward. This is distinct from remodeling, which reconfigures the current square footage.
These projects require a full range of trades that combines architectural planning, permit acquisition, foundation work, rough construction, electrical, plumbing, insulation, drywall, and cosmetic detailing. Because room additions touch so many systems, hiring a experienced builder who can manage all of it is essential.
Room additions are commonly chosen by homeowners who have outgrown their current layout but want to keep their current property. They're often the right move for homeowners planning to age in place. No matter the size, the work follows a structured set of steps that we have mastered through experience.
