For our client in the Betuwe -Holland Evenementen Groep- Ateliereen designed an adventure tower at Beldert Beach, which is a recreational lake. The tower can be used for climbing and other group activities and there is a small kiosk included in the building. There is a viewing platform at a height of nineteen meters, which offers a view over the water, the wide area and the Holland Evenementen Groep. Functionality and visibility were the basic principles for this design. We choose a clear shape, which is formed by the stairs, going inside and outside of the structure. The stairs have a prominent, bright yellow colour. This way the route up is marked and the building has a cheerful and sunny appearance.
The tower is constructed in prefab concrete rings, a robust material with a high-quality finish. The function of the tower is recognizable because the coloured climbing routes contrast with the silver-like background. The project is an addition to the activities of the Holland Evenementen Groep and a new impulse for the beach.
The eleven prefabricated concrete rings all have unique dimensions. In the rings at the top, the logo of Beldert Beach is poured into the surface, so no flags are needed. The rings are approximately 3 x 5 meters. The peculiarity of casting these rings is that only one mold is used, which had to be converted after each ring working from the biggest element to the smallest. Moreover, the architectural concrete requires a high quality surface with little room for errors. The different sloping walls have been an extra challenge whilst pouring and stacking. The tower is designed in such way that the center of gravity is always located above the footprint, also during the stacking of the rings. The kiosk is built with prefabricated walls. By opening the yellow shutters guests are invited to buy a snack at the counter.
