Visually, the new Kielpark towers will be a tribute to the current towers, technically they will be paragons of sustainability. Willemen Construct has been awarded the contract to renovate the first two towers, each containing 96 flats. The building will be equipped with the most sustainable techniques, such as a collective heating installation that works with a heat pump, solar panels for electricity in the common areas, extra insulation and low temperature floor heating. For mobility in the 16-storey building, there will be two large lifts and two closed staircases. In one of the side wings there will be a space that can be used for residents' activities, bicycle storage will be in the basement.
