What do you do when your garage just isn’t enough space anymore?

For this Scottsdale, AZ home, the solution was a 946 square foot attached garage addition paired with interior updates to support how the space would actually be used. Built with high ceilings and a wide-open layout, the addition gives the homeowners room for storage, projects, and everyday use without feeling cramped or disconnected from the home. The result is a clean, functional space that works just as hard as the rest of the house.
