“Christelijke Mutualiteit” (CM) has 4.5 million members, which makes it the largest health insurance fund in Belgium. Under the new motto “Together, everything is better”, the CM wants to put more effort than ever before into handling the many challenges in the healthcare sector, including in South-West Flanders. The Ypres and Kortrijk locations lack space and struggle with an ageing infrastructure, so the organisation opted for a merger in a new building at the Kortrijk Benelux Park. After a thorough needs analysis based on many discussions within the organisation, the B2B interior architecture bureau Arredo created a preliminary design. This gave rise to a sustainable architecture. To further translate this vision into the interior concept, Arredo also advised CM South-West Flanders in the search for a partner for this project and organised a selection procedure.
