Located in the Hughes Center, one block east of The Strip, we sit in the shadow of the Wynn, Palazzo, and Venetian resorts. As international leaders in gaming design, we live and breathe the industry we serve. We got our start in Las Vegas in 1977 as the go-to designer for Coast Properties. Since then, we’ve been a part of the fascinating evolution of this industry and city. Beyond gaming, we’ve helped define our region across a broad spectrum of project types, including higher education, aviation, restaurants, hotels, nightclubs, retail, and other entertainment spaces. We are passionate about creating iconic destinations.
