Design Excellence for the Hospitality Industry Achieving Design Excellence requires uncompromising attention to detail, profound reverence for quality and the guts to step out of bounds in search of a new approach. It goes beyond the surface and demands that every step of the process and every component of the project be examined for its value. D&D is a full-service integrated architecture and interior design firm. We are specialists in hospitality - hotels, resorts, residential lifestyle living and other facilities that are designed for public accommodation. Our work is throughout the United States, Canada, and Asia. Projects include both new construction and renovation. No two projects are ever alike.
