What This Type of Project Covers
Room additions are a broad category that span everything from building an attached garage to full second-story additions. At their core, room additions mean physically extending your home's current floor plan — either upward. This is different than remodeling, which stays inside the current square footage.
These projects demand a collaborative approach that combines architectural planning, building permits, foundation work, framing, electrical, plumbing, insulation, interior finishing, and final finishes. Because room additions involve multiple building disciplines, working with a experienced builder who can manage all of it is essential.
Room additions are ideal for 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. Whether it's a small bump-out or a full-scale addition, the approach follows a well-defined set of phases that our team have executed on hundreds of projects.
