For the past few decades, Rafael Viñoly has helped influence the spaces where we live and work with his innovative architecture. From a series of residential towers bordering Chicago’s iconic Grant Park to a dramatic convention center in Tokyo, the Uruguayan architect has built a reputation for creating structures so daring that at times they appear to defy logic. It's not always easy to explain what makes a building a work of art, but it's “that everybody knows one way or another in the way the proportions work,” says Viñoly. His breathtaking designs are admired around the world, which is one reason he was selected to construct New York’s 432 Park Avenue, the tallest residential building in the Western Hemisphere. This project, perhaps more than any other, says Viñoly, would prove difficult for its physical complexity as well as for its highly visible location next to Central Park. We visited Viñoly in his Manhattan studio to discuss the countless decisions that went into the construction of 432 Park Avenue, as well as the Laguna Garzon in Uruguay and 125 Greenwich Street, his most recent New York project.
