Whether you're ready to build a new bedroom, a larger kitchen, or a guest suite, room additions are the answer.

What Room Additions Entails
Room additions cover a wide range of projects 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 horizontally or vertically. This is distinct from remodeling, which stays inside the existing walls.
These undertakings call for a collaborative approach that brings together architectural planning, building permits, foundation work, rough construction, electrical, plumbing, insulation, drywall, and cosmetic detailing. Because room additions require so many interconnected trades, hiring a experienced builder who can manage all of it is critical.
Room additions are a great fit for homeowners who have outgrown their current layout but prefer to stay in place. They're also a popular choice for homeowners planning to age in place. Whether it's a small bump-out or a full-scale addition, the approach follows a structured set of stages that our team have executed on hundreds of projects.
