CIRCL challenges the status quo in construction
At CIRCL, we recognized a pressing issue of traditional construction methods. Determined to make a difference, we set out to revolutionise the industry by embracing sustainable practices and innovative techniques.
Our goal? To build houses that are energy-efficient and have as little impact on the environment as possible.
According to figures from the United Nations Environment Programme, the traditional building sector is responsible for:
40%
of global CO₂ emissions
36%
of all industrial waste
50%
of global energy consumption

Backed by 100+ years of expertise
CIRCL was born from the Group Vanhout, part of BESIX Group. We combine a fresh perspective with over a century of construction experience. Together with KU Leuven and Buildwise, we developed an innovative construction system that optimises every aspect of the process.
