About Us

Group 41 is a team of seasoned professionals engaged in every type of high-end project, from single family homes, to retail, to corporate and commercial buildings. Our creative staff develops every project with the design attention and depth of any. Our principal, Joel M. Karr is at the helm, and intimately involved in every aspect of a project. This is not a "bait and switch" team where the principal "makes the sale" and then hands off to a junior designer. Joel's work spans 5 countries, with consistently award-winning designs.
