We are a group of thinkers who build, utopian pragmatists whose dreams of impactful design have been forged in the white heat of hard-fought experience.

We are a practice for architecture and urbanism dedicated to advancing cities through the design of lasting public architecture and strategic urban plans. We have a holistic approach that embraces architecture and city planning as allied fields operating along a range of scales. As architects we break down disciplinary boundaries by expanding the definition of our field and rejecting the silos that have ossified our profession. Our designers use both sides of their brains to be as creative as they are analytical. Given the breadth and depth of our team’s talents, but also in an effort to raise labor standards in our field, we treat our personnel with the utmost respect in terms of compensation, staff development, and work-life balance.

Our team, our network of experienced collaborators, and most importantly our clients come to us inspired by our desire to palpably and positively impact the world. Together we thrive on constraints such as program, constructability, public process, regulation, budget and schedule as the fuel for innovation and beauty. To achieve this, from the precise scale of the architectural detail to the large scale of a master plan, ours is a group of “swiss-army knives,” professionals who employ an unprecedented range of skills and mindsets. We are fluent in multiple languages: we speak architecture, we speak culture, we speak ecology, we speak economics, we speak academics, we speak urbanity, we speak government, and perhaps most importantly, we speak the language of democratic public process, because the complexities of the projects we design demand no less.

Below are brief descriptions of the individuals who form our unique collective, a group of thinkers who build, utopian pragmatists whose dreams of impactful design have been forged in the white heat of hard-fought experience.

Vishaan Chakrabarti

Vishaan Chakrabarti


Vishaan Chakrabarti is a registered architect and the founder of PAU. Simultaneously, Vishaan is an Associate Professor of Practice at Columbia University’s Graduate School of Architecture, Planning & Preservation (GSAPP), where he teaches architectural design studios and seminars on urbanism. His highly acclaimed book, A Country of Cities: A Manifesto for an Urban America (Metropolis Books, 2013), argues that a more urban United States would result in a more prosperous, sustainable, joyous, and socially mobile nation. Of the book, the Toronto Globe and Mail wrote: “In the world of urbanism and planning, there’s been a barrage of recent books on similar themes…but Mr. Chakrabarti has written maybe the most useful one, a polemic in favor of city living that makes the stakes clear.” Bruce Katz and Jennifer Bradlee named A Country of Cities one of the top ten books of 2013 in the Huffington Post.

Chakrabarti has been a guest on The Charlie Rose show, MSNBC’s The Cycle, NY1, NPR, WNYC, and has been profiled in The New York Times and The Financial Times. Vishaan has lectured widely across Europe, Asia and the Americas. In April, 2014, the New York Times published his Op Ed, “America’s Urban Future.”

From 2012 to 2015, Vishaan was a principal at SHoP Architects where he co-led major architecture and urban design projects including the master plan and first building at the Domino Sugar site in Williamsburg as well as the master plan and first building at the Essex Crossing site at Seward Park, which together bookend the Williamsburg bridge in a new form of mixed use, mixed income urbanism.

From 2009 to 2015, Vishaan also served as the Marc Holliday Professor and Director of the Master of Science in Real Estate Development program at Columbia’s GSAPP. While there he became the founding director of the Center for Urban Real Estate (CURE). Chakrabarti is widely credited for transforming the program into one of the finest programs of its kind by establishing an interdisciplinary mission that focused on the potential role urban development could play in generating groundbreaking design, greater sustainability, and shared economic prosperity.

From 2005 to 2009, Chakrabarti was the president of Moynihan Station Venture, and remains an ardent advocate for the reconstruction of New York’s Pennsylvania Station. In addition, Chakrabarti was the inaugural Jaquelin T. Robertson Visiting Professor in Architecture for the University of Virginia in 2009.

From 2002 to 2005, Chakrabarti served under Mayor Michael Bloomberg as the Director of the Manhattan Office for the New York Department of City Planning, where he successfully collaborated on the now realized efforts to save the High Line, rezone Hudson Yards, extend the #7 subway line, rebuild the East River Waterfront, expand Columbia University, and reincorporate the street grid at the World Trade Center site after the tragic events of 9/11.

Prior to 2002, Vishaan was an Associate Partner at the New York office of Skidmore, Owings & Merrill LP. There he managed numerous skyscraper projects, including the new headquarters for the New York Stock Exchange, as well as the master plan for Columbia University’s new campus in Manhattanville.

Chakrabarti holds a Master of Architecture from the University of California at Berkeley, a Master of City Planning from the Massachusetts Institute of Technology, and dual bachelor’s degrees in Art History and Engineering from Cornell University.
