Duany Plater-Zyberk & Company (DPZ) is the world leader in the practice and direction of urban planning, having designed over 300 new and existing communities worldwide. DPZ is the Town Planner of Hampstead with Andrés Duany as the Project Manager. DPZ is led by its principals, Andrés Duany and wife Elizabeth Plater-Zyberk, who are co-founders of the Congress for the New Urbanism (CNU), recognized by the New York Times as "the most important collective architectural movement in the United States in the past fifty years." The movement, currently over 3,000 strong, marked a turning point from the segregated planning and architecture of post-war America in favor of promoting time-tested principles of traditional planning & design that created the best-loved and most-enduring places throughout the world.

DPZ’s projects have received numerous awards, including The Richard H. Driehaus Prize for Classical Architecture, 2 National AIA Awards, the Vincent Scully Prize, the Thomas Jefferson Medal and 2 Governor’s Urban Design Awards for Excellence. The firm’s early project of Seaside, Florida, was the first authentic new town to be built successfully in the United States in over 50 years. In 1989, Time Magazine selected Seaside as one of the 10 "Best of the Decade" achievements in the field of design. In 2004, Builder Magazine recognized Duany as among the 50 most influential people in home building. Duany was ranked after Alan Greenspan and George W. Bush, earning Duany the distinction of being the top ranking individual from the private sector. DPZ has been featured in other national media such as NBC News and ABC News, as well as Newsweek, the New York Times, the Washington Post, and the New Yorker.

The firm's method of integrating master plans with project-specific design codes can be seen in sites ranging from 10 to over 500,000 acres throughout the United States. Abroad, DPZ projects are underway in the United Kingdom, Canada, Germany, Belgium, Australia, the Philippines, Mexico, and South America. DPZ also specializes in comprehensive urban redevelopment and sprawl repair as seen in Miami, Providence, and the hurricane-devastated towns of Louisiana and Mississippi.
