We found the inspiration for the design of the lookout tower in the characteristic trees of the Kohoutovice forests - oaks. Just as the oak trunk consists of several interconnected layers, the lookout tower also consists of several layers. The rigid supporting core of the lookout tower paraphrases the supporting component of the tree trunk, ie the wood and the "skirt" of the lookout tower made of steel ropes corresponds to the furrowed bark of the trunk. The dramatic furrowing of the bark is symbolically expressed by the rhombus texture of the arrangement of the steel ropes of the outer shell. The basic architectural intention is to rewrite the structure of the oak trunk.
The technical design solution is based on the requirements for maximum safety of visitors, long life and easy maintenance of the structure. The exposure of the building to the weather significantly affected the final appearance of the structure. The floor of the viewing platform is located 34.32 m above the ground. The structure is designed as a rigid cylindrical supporting steel core with a drawn outer shell of steel rods also arranged in a circle in plan. The steel rods of the outer shell of the lookout tower - form the load-bearing part of the structure stressed only by tension, while the rigid central load-bearing shaft is stressed mainly by pressure. The service life of the steel structure can be guaranteed for a long time, and in addition requires minimal inspection and maintenance. The surface treatment is designed in the form of hot-dip galvanizing. The steel structure of the lookout tower is mounted on a massive reinforced concrete foundation slab hidden under the ground.
