What This Type of Project Covers
Room additions cover a wide range of projects that include everything from adding a single bedroom to major kitchen expansions.

These builds call for a coordinated effort that combines architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, drywall, and final finishes.
