Whether you're planning for a new bedroom, a functional office, or a sunroom, room additions can make it happen.

What This Type of Project Involves
Room additions are a broad category that span everything from adding a single bedroom to major kitchen expansions. At their foundation, room additions involve expanding your home's existing structure — either outward. This is not the same as remodeling, which works within the original layout.
These undertakings require a collaborative approach that involves architectural planning, city approvals, foundation work, framing, electrical, plumbing, insulation, interior finishing, and cosmetic detailing. Because room additions require so many interconnected trades, working with a skilled construction team who can coordinate each phase is critical.
Room additions are a great fit for homeowners who have outgrown their current layout but prefer to stay in place. They're also a popular choice for multigenerational households. Regardless of the scope, the process follows a structured set of stages that our builders have mastered through experience.
