What Home Addition Work Entails
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 involve expanding your home's current floor plan — either upward. This is distinct from remodeling, which reconfigures the existing walls.
These builds call for a coordinated effort that brings together architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, wall systems, and cosmetic detailing. Because room additions require so many interconnected trades, hiring a skilled construction team who can coordinate each phase is critical.
Room additions are a great fit for homeowners who need more room but want to keep their current property. They're also a popular choice for multigenerational households. Regardless of the scope, the process follows a well-defined set of steps that our team have executed on hundreds of projects.
