Whether you're dreaming of a new bedroom, a larger kitchen, or a dedicated workspace, room additions can make it happen.

What This Type of Project Covers
Room additions encompass many different types of construction that span everything from building an attached garage to full second-story additions. At their core, room additions mean physically extending your home's existing structure — either outward. This is distinct from remodeling, which reconfigures the current square footage.
These undertakings demand a full range of trades 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 experienced builder who can oversee every step is essential.
Room additions are ideal for homeowners who have outgrown their current layout but aren't ready to move. They're often the right move for homeowners planning to age in place. Regardless of the scope, the process follows a clear set of phases that our team have refined over many years.
