What This Type of Project Involves

Room additions cover a wide range of projects that span everything from building an attached garage to full second-story additions. At their core, room additions mean physically extending your home's current floor plan — either upward. This is different than remodeling, which reconfigures the existing walls.

These undertakings demand a full range of trades that brings together architectural planning, building permits, foundation check here work, structural carpentry, electrical, plumbing, insulation, wall systems, and cosmetic detailing.
