GTB Lab - Phase 2
Laboratory for Green Transformable Building


building
Summary
The GTB Lab building is being built as a circular building laboratory to test and demonstrate circular building methods. It is an innovation platform for zero-waste construction, where the credo is: Demolition waste is a design flaw,” says Elma Durmisevic, founder and creator of GTB Lab©.
Details
Buildings that are dynamically and flexibly constructed from reusable materials have an essential driving function in the transition to a circular (building) economy. They serve as temporary storage for valuable building materials. In circular construction not a brick or a screw is thrown away. This is the idea behind the Green Transformable Building Lab (GTB Lab©) in Heerlen.
