What Room Additions Covers

Room additions are a broad category that involve everything from building an attached garage to major kitchen expansions. At their heart, room additions require adding to your home's current floor plan — either horizontally or vertically. This is different than remodeling, which reconfigures the existing walls.

These projects call for a coordinated effort that combines architectural planning, permit acquisition, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and final finishes. Because room additions involve multiple building disciplines, working with a experienced builder who can coordinate each phase is critical.

Room additions are a great fit for homeowners who have outgrown their current layout but want to keep their current property. They're often the right move for families welcoming new members. Regardless of the scope, the process follows a clear set of steps that we have executed on hundreds of projects.
