What Home Addition Work Involves

Room additions cover a wide range of projects that include everything from adding a single bedroom to large-scale family room builds. At their heart, room additions mean physically extending your home's current floor plan — either outward. This is distinct from remodeling, which stays inside the current square footage.

These projects demand a full range of trades that brings together architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, drywall, and flooring and trim. Because room additions require so many interconnected trades, working with a experienced builder who can coordinate each phase is the key to a smooth project.
