20.000 BLOCKS

The content of this page is only available in German. Please go to German version of this page.

20.000 BLOCKS is a framework for collaborative design built on Minecraft where architects and players can create buildings and cities together in a collaborative, creative process.

The framework allows the creation of architectural games where players are given a goal and insufficient resources to achieve it. They advance in the game by building shapes out of Minecraft blocks, choosing from a predefined catalogue of architectural items. While players compete to reach the goal, a building emerges out of the shapes that they have built. Player creations can be exported to Rhino/Grasshopper for further analysis or to be turned into wooden models by our UR10 robot Ginger.

Our team used 20.000 BLOCKS to create the IBA_GAME for IBA Heidelberg. 20.000 BLOCKS has been published in Wired Germany and featured on the TV channel ARTE. The project has been presented at events and conferences around the world such as CEBIT, SmartGeometry, ACADIA and the World Design Symposium.

20.000 BLOCKS is developed by Anton Savov within his research on crowdsourced and massively-collaborative design at the DDU. Ben Buckton has contributed significantly to 20.000 BLOCKS both conceptually and in code.
