What Home Addition Work Entails
Room additions cover a wide range of projects that include everything from constructing a new bathroom to full second-story additions. At their foundation, room additions require adding to your home's existing structure — either horizontally or vertically. This is not the same as remodeling, which reconfigures the current square footage.
These builds require a full range of trades that involves architectural planning, building permits, foundation work, structural carpentry, electrical, plumbing, insulation, interior finishing, and final finishes. Because room additions involve multiple building disciplines, hiring a experienced builder who can manage all of it is critical.
Room additions are commonly chosen by homeowners who want a dedicated space but prefer to stay in place. They're also a popular choice for homeowners planning to age in place. Regardless of the scope, the work follows a well-defined set of phases that we have refined over many years.
