What This Type of Project Entails
Room additions are a broad category that involve everything from adding a single bedroom to full second-story additions. At their foundation, room additions involve expanding your home's current floor plan — either horizontally or vertically. This is distinct from remodeling, which stays inside the current square footage.
These projects call for a coordinated effort that involves architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, drywall, and final finishes. Because room additions involve multiple building disciplines, hiring a skilled construction team who can manage all of it is critical.
Room additions are ideal for homeowners who need more room but prefer to stay in place. They're frequently selected for multigenerational households. Regardless of the scope, the approach follows a well-defined set of steps that we have mastered through experience.
