Architect Stefanos Polyzoides is a godfather of the hugely influential movement in architecture and urban planning known as the New Urbanism. All those suburbs that decided to put in little downtowns and walkable areas? The whole loft thing? Infill development that puts condos in empty lots instead of sprawl out in the exurbs? Credit Polyzoides, his wife, Elizabeth Moule, and a small group of colleagues for co-founding the influential movement—and Polyzoides for giving it a name. Today the couple speak and write widely on the topic.
