What This Type of Project Covers
Room additions are a broad category that include everything from constructing a new bathroom to major kitchen expansions. At their foundation, room additions require adding to your home's current floor plan — either outward. This is different than remodeling, which works within the existing walls.
These undertakings demand a collaborative approach that combines architectural planning, building permits, foundation work, framing, electrical, plumbing, insulation, drywall, and flooring and trim. Because room additions require so many interconnected trades, hiring a general contractor who can oversee every step is the key to a smooth project.
Room additions are commonly chosen by homeowners who have outgrown their current layout but want to keep their current property. 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 work follows a well-defined set of phases that our team have refined over many years.
