At KALK we are passionate about creating a sustainable building culture worthy of preservation in which we construct buildings that can be preserved in the future. Buildings consisting of materials that can be repaired and reused over and over again. Buildings made from natural raw materials of high quality ensuring that they will neither damage our environment or health. Buildings made from resources there will be enough of in the future. We want to create the sustainable building of the future. We call it 'Build lasting culture'.
