What This Type of Project Covers
Room additions cover a wide range of projects that include everything from constructing a new bathroom to major kitchen expansions. At their heart, room additions require adding to your home's current floor plan — either outward. This is different than remodeling, which works within the current square footage.
These builds demand a coordinated effort that combines architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and flooring and trim. Because room additions involve multiple building disciplines, hiring a experienced builder who can oversee every step 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 frequently selected for families welcoming new members. Regardless of the scope, the work follows a clear set of stages that our team have refined over many years.
