Modular residential construction for sustainable development
CIRCL supports developers, architects, real estate investors and housing associations in Belgium and the Netherlands in realising complete and scalable residential projects — from housing developments with single-family homes to multi-unit urban buildings.
With our innovative modular building system, we deliver weatherproof and airtight homes within 12 weeks, fully EPB/BEN-certified and built according to circular construction principles.
Our roots lie with the Vanhout Group (part of the BESIX Group), and our building method was developed in collaboration with KU Leuven and Buildwise.
This unique combination of more than a century of construction expertise and cutting-edge innovation makes CIRCL the strategic partner of choice for developers seeking strong returns — and for architects aiming to design sustainable, future-ready projects.
