What Home Addition Work Involves
Room additions are a broad category that include everything from adding a single bedroom to major kitchen expansions. At their foundation, room additions involve expanding your home's current floor plan — either upward. This is different than remodeling, which stays inside the current square footage.
These projects call for a coordinated effort that involves architectural planning, permit acquisition, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and final finishes. Because room additions involve multiple building disciplines, 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 want to keep their current property. They're frequently selected for homeowners planning to age in place. Regardless of the scope, the process follows a structured set of phases that our builders have executed on hundreds of projects.
