This construction kit has 1,600 plastic parts that interlock to build a 5' skyscraper or countless other edifices, honing aspiring architects' spatial intelligence and problem solving skills. Twelve pages of authentic, full-scale blueprints on 33" x 21" paper provide detailed drawings and instructions for building model skyscrapers from plan, isometric, and detailed views. The fundamentals of schematic architecture are demonstrated through techniques for erecting load-bearing walls, curved walls, and arches. Young architects can list their buildings on an interactive world map on the manufacturer's website; select the latitude and longitude for a proposed skyscraper, submit the estimated height and number of pieces required for its construction, and the manufacturer provides a PDF of a building permit with the seismic and wind loads for the proposed building. The interlocking walls snap together without the use of glue, ensuring an entirely reusable kit. Ages 10 and up. (13 1/2 lbs.)
