About us

BC materials is a workers' cooperative founded in October 2018 by Ken De Cooman, Nicolas Coeckelberghs, Laurens Bekemans & Wes Degreef, with the mission to spread & grow earth construction as one of the most important solutions to counter the enormous environmental impact of the construction sector. 

With a diverse team of around 10 people consisting of architects, philosophers, engineers and crafts(wo)men, we provide tailor made solutions to your projects through our 4 activities:

• consultancy & development
• design & prefabrication
• ​​​​​​bespoke production
• workshops & training

The knowledge acquired through these 4 activities allow for continuous innovation and development of our circular earth building material range called Léém. With Léém, we aim to democratise the market for circular earth building materials, and for this we are partnering with industrial actors such as Brickz for commercialisation, and Vande Moortel and Claesen Betonbedrijf for production.

BC is BC architects & studies & materials. BC stands for Brussels Cooperation and points to how BC grew - embedded within place and people. We operate through 3 legal entities registered in Belgium: BC architects bv (architecture company), BC studies vzw (non-profit education laboratory), BC materials cv (material production cooperative). BC is a hybrid practice, designing and undertaking "acts of building" towards systemic change in the construction sector. We strive for bioregional, low-tech, circular, beautiful and inclusive design. We work with our minds and our hands, undertaking activities such as community organisation, material production, contracting, teaching, prototyping. We aim to impact positively on people's ideas and planet. We act on behalf of the generations after us.
