What Home Addition Work Covers
Room additions are a broad category that span everything from adding a single bedroom to full second-story additions. At their heart, room additions involve expanding your home's existing structure — either upward. This is distinct from remodeling, which works within the current square footage.
These undertakings demand a collaborative approach that involves architectural planning, building permits, foundation work, framing, electrical, plumbing, insulation, drywall, and flooring and trim. Because room additions involve multiple building disciplines, choosing a general contractor who can manage all of it is the key to a smooth project.

No matter the size, the process follows a structured set of steps that our builders have executed on hundreds of projects.
