What Home Addition Work Entails

Room additions are a broad category that include everything from constructing a new bathroom to full second-story additions. At their foundation, room additions require adding to your home's footprint — either upward. This is not the same as remodeling, which stays inside the existing walls.

Because room additions require so many interconnected trades, hiring a experienced builder who can oversee every step is the key to a smooth project.

Room additions are ideal for homeowners who want a dedicated space but prefer to stay in place. They're often the right move for multigenerational households. No matter the size, the approach follows a structured set of steps that our team have mastered through experience.
