What Room Additions Covers

Room additions cover a wide range of projects that include everything from adding a single bedroom to full second-story additions.

These undertakings call for a collaborative approach that brings together architectural planning, building permits, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and flooring and trim.
