PIENSA SOL is an ideas contest about the future of the “Puerta del Sol” in Madrid organized by Madrid city, Madrid Council, Fundación Arquitectura COAM, and Madrid Think Tank.



Because of the celebration of the X Architecture Week, today opens from 16: 00h in the afternoon at the headquarters of the COAM, a huge scale model of the “Puerta del Sol”, produced 100% in cardboard, that will be the epicenter of all activities related to the contest in the coming months.



CartonLAB, commissioned by the Coam Foundation, participated in the assembly, structural design and production of the model, comprised of over 165 cardboard sheets (one ton of material) and the installation was completed in just 24 work hours.



The model is formed by several audiovisual pieces that show us “Sol” from every point of view and also how was the traffic of the square between the nineteenth and twentieth centuries, besides you can explore the successive transformations over time. On the other hand, Jose Luis Rayos has done a wonderful piece with neon lighting inspired by the traditional sign “Tio Pepe”.
