What This Type of Project 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 core, room additions involve expanding your home's current floor plan — either upward. This is different than remodeling, which works within the existing walls.

These projects call for a full range of trades that involves architectural planning, permit acquisition, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and final finishes. Because room additions involve multiple building disciplines, hiring a experienced builder who can manage all of it is essential.

Room additions are commonly chosen by homeowners who need more room but aren't ready to move. They're frequently selected for homeowners planning to age in place. Whether it's a small bump-out or a full-scale addition, the approach follows a clear set of phases that our builders have refined over many years.
