What Room Additions Covers
Room additions cover a wide range of projects that include everything from building an attached garage to large-scale family room builds. At their foundation, room additions require adding to your home's current floor plan — either outward. This is different than remodeling, which stays inside the original layout.
These undertakings call for here a collaborative approach that combines architectural planning, permit acquisition, foundation work, rough construction, electrical, plumbing, insulation, drywall, and cosmetic detailing. Because room additions require so many interconnected trades, hiring a general contractor who can coordinate each phase is critical.
Room additions are ideal for homeowners who need more room but want to keep their current property. They're also a popular choice for multigenerational households. Whether it's a small bump-out or a full-scale addition, the approach follows a well-defined set of steps that our team have executed on hundreds of projects.
