What Room Additions Covers
Room additions are a broad category that include everything from building an attached garage to major kitchen expansions. At their foundation, room additions mean physically extending your home's current floor plan — either outward. This is not the same as remodeling, which stays inside the original layout.
These projects call for a coordinated effort that brings together architectural planning, permit acquisition, foundation work, rough construction, 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 the key to a smooth project.
Room additions are a great fit for homeowners who want a dedicated space but want to keep their current property. They're frequently selected for multigenerational households. No matter the size, the work follows a structured set of stages that our team have executed on hundreds of projects.
