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 core, room additions involve expanding your home's existing structure — either outward. This is not the same as remodeling, which reconfigures the existing walls.

These builds require a coordinated effort that brings together architectural planning, building permits, foundation work, framing, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions require so many interconnected trades, choosing a general contractor who can coordinate each phase is critical.

Room additions are a great fit for homeowners who want a dedicated space but prefer to stay in place. They're often the right move for families welcoming new members. No matter the size, the approach follows a well-defined set of stages that our team have mastered through experience.
