Tree Tower
The tower structure consists of an external circular ring based on nine glued-laminated timber columns which have been arranged in rotational symmetry and set up with an angle difference of 40° each, thus forming a polygonal, spatial structure.
A steel pylon made of a round pipe was built inside the tower. Steel spiral stairs with steel grids and a tunnel slide are attached to the pylon, which is connected to the tower at two height levels: at 24 m (78.7 ft) and 40.175 m (131.2 ft).
Visitors have access to the tower using the treetop walkway, ending at 24 m (78.7 ft) above the ground, or climbing the spiral staircase. From there, they can reach the viewing platform by climbing a spiral timber structure that is attached to the timber columns by means of cantilevered steel beams.
The structure has been stiffened by a close mesh of diagonal steel members anchored in the timber columns. Furthermore, four horizontal ring structures consisting of steel pipes have been arranged in the lower part of the tower.
