What This Type of Project Entails
Room additions cover a wide range of projects that span everything from building an attached garage to full second-story additions.

These projects require a collaborative approach that involves architectural planning, building permits, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and final finishes. Because room additions require so many interconnected trades, working with a skilled construction team who can oversee every step is essential.
