Who We Are

DPZ CoDesign has been a leader in the practice of planning and urban design for over 30 years. Our philosophy is the platform of New Urbanism, a movement promoting mixed-use, traditional neighborhood planning over the segregated-use suburban sprawl seen worldwide. Co-founders of the Congress for New Urbanism (CNU), DPZ’s principals have been longtime advocates of urban growth through compact, pedestrian-oriented, transit-friendly communities that continue to shape policy and have recently influenced new sustainability codes.

Our Method

DPZ works under many arrangements, tailoring the process for each project.  From conventional multi-step engagements, to pure research addressing contemporary problems, to the charrette, we seek informed efficiency and integrity of result.

The charrette is a dynamic and stimulating process of design.  A week-long work session assembles key decision-makers in an iterative design cycle of proposals, feedback and revisions, organizing a complex project quickly.  Rapid prototyping ensures informed choices and saves months of sequential coordination.  In a private setting or with a public audience, the charrette ensures a comprehensive approach and builds support for the vision. 

DPZ assists project implementation through approvals, and in many cases, marketing, first-phase detailing, and construction.  For new community plans, a Town Architect is often identified to guide subsequent phases of construction.

The term ‘charrette’ is derived from the French word ‘little cart’, referring to the 19th century École de Beaux Arts method of transporting students’ drawings while last-minute finishing touches were being applied.

Our History

DPZ was founded in 1980 by Andres Duany and Elizabeth Plater-Zyberk as an architectural practice.  Identifying the deficiencies of the suburban context for their early buildings led to a rediscovery of neighborhood structure and influenced the design of Seaside, acclaimed for its traditional town plan, streetscapes and buildings.

Recognizing the need for an alternative to suburban zoning, the firm proposed a re-integration of urban components with the Traditional Neighborhood Development (TND) in 1990.  The TND became a model regulation for compact mixed-use neighborhood design, informing hundreds of municipal ordinances throughout the country. 

With several new communities well underway, Duany and Plater-Zyberk joined contemporaries to found the Congress for the New Urbanism (CNU) in 1993.  CNU’s charter, annual meetings and numerous policy initiatives, are guiding an international movement of sustainable urban growth and community design.  The firm’s subsequent initiatives have generated documents that reflect DPZ’s commitment to ‘open source’ – the Lexicon, SmartCode, Transect, Lean Urbanism, Sprawl Repair, Light Imprint, among them.

Today the firm counts over 300 projects built, ranging from individual buildings and small urban infill projects to new communities, regional plans and zoning codes. Over 150 alumni of the firm continue to impact the built environment advancing lessons learned at DPZ.

Our Partners

Diverse in background, DPZ’s leaders enable the firm’s global reach. The partners are thought leaders, certified professionals, experienced designers, skilled facilitators for the public process, educators, seasoned speakers, and disarmingly charming.
