Welcome to the international knowledge platform for circular building.

On this website you will find the latest information on circular building. We work with academic institutes, policy makers and industry partners around the world to generate and disseminate knowledge that enables the transition to circular building.

We provide know-how and support for circular building projects. You will find strategies, tools, guidelines and lessons learned from exemplary projects. The Knowledge Platform also serves as a monitoring system for circular material flows in regions by tracking the material consumption of building projects. The circular map shows you where to find circular partners and how many tons of building materials are consumed and reused in your region. Avoiding waste starts with knowledge about circular construction.

Our platform was initiated by GTB Lab in collaboration with the Dutch Ministry of the Interior and Kingdom Relations and the Province of Limburg to contribute to knowledge and effective circular practices and policies in the construction sector. The Circular Building Knowledge Platform is the digital leg of the European Laboratory for Green Transformable Buildings (GTB Lab). The other leg is the physical building in Heerlen (NL). GTB Lab is a unique European laboratory that introduces a systemic change in the building sector. A new philosophy where waste is considered a design flaw.
