The result of a study into the application of Ultra High Performance Concrete, this 25 meter high observation tower by UNStudio really puts the material to the test. The innovative concrete differs from the norm in that it is extremely dense, has steel fibers, and maintains a fine grain structure. Its use in the tower makes it possible to achieve the fluid, eye-catching shape with minimal obstruction of the views.
The design for the observation tower guides visitors in a fluid ascent up the 134 steps to the highest viewing point. Visitors are lead via the first set of steps to the lower viewing platform which stands at a height of 10 metres. Following this, the second set of steps provides a turn in direction, allowing for an alternative view of the surrounding forested pastures. These steps lead visitors through the tree tops to the second viewing platform which stands at a height of 20 metres and offers views over the nature reserve around the city of Groningen. The highest viewing platform, at a height of 24 metres, is reached via the final set of steps and offers visitors a wide open vista of ‘De Onlanden’ nature reserve.
