How can open Modular construction can impact design practice? After his studies at the Design Academy Eindhoven, Les Ateliers Paris and the Institute without Boundaries Toronto, Thomas Lommée (*1979) has participated in a series of multidisciplinary design research groups in Europe and overseas. In 2007 he established "Intrastructures", a pragmatic, utopian design-studio, that emphasizes on the physical, digital and social context of product-design. He is the initiator of the OpenStructures project, a hands-on design experiment that explores the possibility of a modular construction model where everyone designs for everyone on the basis of one shared geometrical grid. According the UK Wired his Open Structures model is one of the 25 big ideas of 2012. Currently Thomas Lommée teaches at the research programme Social Design at Design Academy Eindhoven's Master course and at the Ecole nationale supérieure de création industrielle in Paris. He lives and works in Brussels.
