Logo GTB Lab

GTB Lab is a unique European Laboratory introducing a systemic shift in the building sector. A new philosophy where waste is considered a design error.

GTB Lab will be built under the umbrella of IBA Labor as an important part of the IBA Sustainable Innovations. By building the lab, new concepts and production processes for transformation and re-use of buildings as well as building parts

will be researched and tested. By designing for circular value chains buildings will continuously increase their value.

These dynamically and flexibly designed buildings are the key to a circular economy. Instead of being to-be waste, buildings will function as banks of valuable materials. In this context new business models will be developed to enable the shift toward a circular economy.

DDC - Until 2023 GTB Lab is initiating partner of Digital DeConstruction (DDC); the Interreg project in which a Digital Support Platform is developed to enable circular (de)construction.

BAMB - In the past years GTB Lab has been one of the important pillars of BAMB - Buildings As Material Banks; the European project that is working towards new EU standards and regulations for circular building in Europe.


Earth from the moon


Due to technological and ICT revolutions, we are witnessing increasing acceleration of change almost on daily bases in all fields. These changes affect the way we communicate, work, learn, live, while trends and predictions risk to be overrun at the time they are identified as such.

What is the physical answer to this increasing dynamics, considering

the capacities of the planet and human physical and psychological needs?


The world of tomorrow is an upgradable world with dynamic and reversible buildings.
Design needs to guarantee circular value chains, through which buildings and materials in buildings will sustain / increase their value.

Instead of being designed for demolition and to become waste,

reversible building design gives buildings capacity to reverse the processes and building structures back to the initial set of elements and to re-configure them to answer new requirements.

Dynamic and Circular Building is

shaping the world of tomorrow. A world in which building demolition and construction waste are considerd a Design Mistake.

Founder of GTB Lab

GTB Lab was founded in 2009 by Dr. Elma Durmisevic. A first kick off symposium was held December 4th 2009 where she presented her vision. As a result a first cluster of participating companies was formed in 2010.
