What This Type of Project Covers
Room additions cover a wide range of projects that involve everything from constructing a new bathroom to full second-story additions. At their core, room additions require adding to your home's current floor plan — either upward. This is distinct from remodeling, which stays inside the current square footage.
These projects demand a full range of trades that combines architectural planning, permit acquisition, foundation work, framing, electrical, plumbing, insulation, interior finishing, and cosmetic detailing. Because room additions touch so many systems, working with a skilled construction team who can manage all of it is critical.
Room additions are a great fit for homeowners who need more room but prefer to stay in place. They're frequently selected for homeowners planning to age in place. No matter the size, the process follows a clear set of steps that we have refined over many years.
