Landscape architects are the ninjas of the design world, silently orchestrating beauty around buildings while you’re too busy staring at your phone. They decide whether that park bench is in the sun or shade, the exact curve of a sidewalk, and how to make an average building look extraordinary.  They’re the ones who make sure your city doesn’t feel like a concrete jungle and that your suburban sprawl doesn’t completely lose touch with nature. Today we’ll talk with two exceptional landscape architects, Chris LaGuardia and Michael Van Valkenburgh. Later, music with Pink Martini’s Timothy Nishimoto.
