The two bunkers are additions made in 1936 to the nineteenth century New Dutch Water line of defense; an 85km long protective garland of military objects combined with an intricate water management system which enabled the inundation of land in case of attack. For a number of years they have formed part of an estate that is slowly being developed as a mixture of high-end business and sporting facilities. Stables and polo fields form the core of the estate. The structure on top of the first bunker is intended as a business retreat. It consists of a single, large room with some elementary facilities. The seamless, stainless steel façade is orientated towards the polo field with its single window. A glass skylight enforces the smooth, car-like appearance of the structure.
