The OS (OpenStructures) project explores the possibility of a modular construction model where everyone designs for everyone on the basis of one shared geometrical grid. It initiates a kind of collaborative Meccano to which everybody can contribute parts, components and structures. It is an ongoing experiment that wants to find out what happens if people design objects according to a shared modular grid, a common open standard that stimulates the exchange of parts, components, experiences and ideas and aspires to build things together.

The OpenStructures project is a collaborative effort. It was originally conceived at the Institute without Boundaries and is now being further developed and tested by Intrastructures in association with the research group 4Dimensional Design of the Department of Architectonic Engineering Sciences at the Vrije Universiteit Brussel.
