What This Type of Project Involves
Room additions are a broad category that span everything from constructing a new bathroom to full second-story additions. At their foundation, room additions require adding to your home's existing structure — either outward. This is different than remodeling, which works within the existing walls.
These projects call for a full range of trades that brings together architectural planning, building permits, foundation work, structural carpentry, electrical, plumbing, insulation, drywall, and final finishes. Because room additions touch so many systems, working with a skilled construction team who can coordinate each phase is critical.

Regardless of the scope, the approach follows a structured set of phases that our builders have mastered through experience.
