What Home Addition Work Involves
Room additions are a broad category that involve everything from building an attached garage to full second-story additions. At their core, room additions require adding to your home's current floor plan — either outward. This is different than remodeling, which reconfigures the original layout.
These projects call for a coordinated effort that brings together architectural planning, permit acquisition, foundation work, framing, electrical, plumbing, insulation, drywall, and final finishes. Because room additions require so many interconnected trades, choosing a experienced builder who can coordinate each phase is the key to a smooth project.
Room additions are commonly chosen by homeowners who need more room 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 structured set of phases that we have mastered through experience.
