Architect Richard Dattner, FAIA, has been fascinated with modular design since his student days at MIT. Parallel to a career in civic architecture he has designed and patented a number of modular structures—including a modular house, PlayCubes and Habitot play equipment, Shelterscape canopies and shelters, and Streetscape booths. Come and hear about the highs (the fun of designing), lows (patent infringement, material costs, money), and happy outcome (the relaunch of PlayCubes) of this career-long adventure.
