What Home Addition Work Covers
Room additions cover a wide range of projects that span everything from adding a single bedroom to large-scale family room builds. At their heart, room additions involve expanding your home's current floor plan — either horizontally or vertically. This is distinct from remodeling, which works within the existing walls.
These undertakings call for a full range of trades that involves architectural planning, permit acquisition, foundation work, rough construction, electrical, plumbing, insulation, wall systems, and flooring and trim. Because room additions require so many interconnected trades, hiring a experienced builder who can coordinate each phase is critical.
Room additions are commonly chosen by homeowners who have outgrown their current layout but prefer to stay in place. They're frequently selected for homeowners planning to age in place. No matter the size, the approach follows a clear set of phases that our builders have mastered through experience.
