What This Type of Project Entails
Room additions are a broad category that include everything from constructing a new bathroom to major kitchen expansions. At their heart, room additions require adding to your home's current floor plan — either outward. This is not the same as remodeling, which works within the existing walls.
These builds call for a full range of trades that combines architectural planning, building permits, foundation work, structural carpentry, electrical, plumbing, insulation, wall systems, and cosmetic detailing. Because room additions touch so many systems, choosing a skilled construction team who can oversee every step is critical.
Room additions are ideal for homeowners who have outgrown their current layout but prefer to stay in place. They're frequently selected for homeowners planning to age in place. Regardless of the scope, the work follows a well-defined set of steps that we have refined over many years.
