What This Type of Project Covers
Room additions are a broad category that include everything from adding a single bedroom to full second-story additions. At their core, room additions require adding to your home's current floor plan — either upward. This is distinct from remodeling, which reconfigures the existing walls.
These projects call for a coordinated effort that combines architectural planning, permit acquisition, foundation work, framing, electrical, plumbing, insulation, wall systems, and final finishes. Because room additions involve multiple building disciplines, hiring a skilled construction team who can manage all of it is essential.
Room additions are commonly chosen by homeowners who have outgrown their current layout but want to keep their current property. They're often the right move for homeowners planning to age in place. Regardless of the scope, the process follows a well-defined set of steps that we have executed on hundreds of projects.
