CBT’s urban design team has played an important role in a broad range of projects in diverse urban settings, focusing on the rejuvenation of downtowns, waterfronts, neighborhoods, brownfield sites, planning for urban campuses and transformation of complex infrastructure and transportation elements into livable communities. Our designs build on the unique qualities and character of each context while successfully supporting the economic potential of each place. With each project, our constant focus on environmental sustainability, unique design sensibility, strategic consensus-building approach, and communication and presentation methods have led to the creation of great new communities. Today, CBT’s Urban Design Studio is an ever-accelerating and evolving center of knowledge and research around the imperatives that are affecting global development and we dedicate our practice to creating and improving durable, smart, connected, and resilient places for today and far into the future.
