The design of the housing of the third waste incineration line of Twence named Triade is designed in cooperation with Tebodin and BDG. The concept consists of a sculptural folded skin, wrapped around the installation. The skin is amphibious: flexible but protecting, permeable for light and air. The green/blue two tone colouring of the façade entertains the spectator who passes the building and sees how the colour of the building transforms from one into the other and back again.
