What This Type of Project Covers

Room additions are a broad category that span everything from building an attached garage to full second-story additions. At their foundation, room additions mean physically extending your home's existing structure — either horizontally or vertically. This is distinct from remodeling, which reconfigures the original layout.

These undertakings call for a full range of trades that involves architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and flooring and trim. Because room additions require so many interconnected trades, working with a general contractor who can manage all of it is critical.

Room additions are commonly chosen by homeowners who need more room but want to keep their current property. They're frequently selected for families welcoming new members. Regardless of the scope, the process follows a clear set of stages that we have refined over many years.
