What Home Addition Work Covers
Room additions encompass many different types of construction that involve everything from constructing a new bathroom to full second-story additions. At their foundation, room additions involve expanding your home's current floor plan — either outward. This is not the same as remodeling, which works within the current square footage.
These builds require a collaborative approach that brings together architectural planning, building permits, foundation work, structural carpentry, electrical, plumbing, insulation, wall systems, and cosmetic detailing. Because room additions require so many interconnected trades, choosing a experienced builder who can coordinate each phase is essential.
Room additions are a great fit for homeowners who have outgrown their current layout but prefer to stay in place. They're frequently selected for multigenerational households. Regardless of the scope, the approach follows a well-defined set of stages that our team have refined over many years.
