What Home Addition Work Involves

Room additions encompass many different types of construction that include everything from adding a single bedroom to large-scale family room builds. At their foundation, room additions require adding to your home's existing structure — either upward. This is distinct from remodeling, which works within the existing walls.

These undertakings demand a collaborative approach that involves architectural planning, permit acquisition, foundation work, rough construction, electrical, plumbing, insulation, drywall, and cosmetic detailing. Because room additions involve multiple building disciplines, working with a experienced builder who can coordinate each phase is critical.

Room additions are a great fit for homeowners who need more room but aren't ready to move. They're often the right move for multigenerational households. Regardless of the scope, the work follows a well-defined set of phases that our team have refined over many years.
