What Home Addition Work Covers
Room additions encompass many different types of construction that span everything from adding a single bedroom to large-scale family room builds. At their core, room additions require adding to your home's current floor plan — either upward. This is different than remodeling, which reconfigures the current square footage.
These builds demand a collaborative approach that combines architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and flooring and trim. Because room additions touch so many systems, hiring a general contractor who can manage all of it is essential.

Whether it's a small bump-out or a full-scale addition, the process follows a structured set of phases that our builders have refined over many years.
