Lookout Tower at Kraličák Ski resort designed by Huť Architektury is a year-round accessible 35 meters tower made from wooden larch logs.

Located centrally at the highest point of Stvanice hill in Czech Republic, the tower overlooks the picturesque natural landscape and old town of Jeseniky mountain. Larch logs being highly resistant to pressure have been largely used for construction. Connected by steel joints at every 5 meters and strengthened by stiffeners, steel cables, the observatory rises around a central staircase.

From the Architects –

The lookout tower is a result of several years of collaboration with the local ski resort Kraličák. It is situated at the highest point between Hynčice and Stříbrnice on the hilltop Štvanice 866 m.a.s.l. The supposed center of the resort, on the hill in the forest amongst ski slopes. Around it is a beautiful dramatic vast landscape.

Surrounded by tall trees, the tower gives view of nearby old town


The old town, a view of the entire Jeseníky mountains, on the other side, the heavily wooded hillside of Králický Sněžník where the Morava river springs from. The assignment has been fulfilled, a year-round accessible, 35 meter tall lookout tower, situated at the top station of the chair lift – the center of the resort.

Lookout Tower details –

The tower stands here as a confident slim round obelisk. A center-point. A simple structural diagram, a slim, 35m tall vertical secured by cables. While designing, we were searching for economical, rational solutions that would be an answer to the assignment. We try to base the idea on the location. Stone/wood.

Construction using larch wood


As a construction material we chose larch logs. It is used in the way it is pretty much present all around. The tree trunks standing vertically, connected together, elevating the viewing platform, protected against wind by safety glass. In the center of the tower hangs a round wooden staircase, like a pendulum, it balances the gusts of wind.

Centrally located wooden staircase


Viewing platform and construction – 

After 152 steps, you ascend above treetops of the surrounding forest. Above you are only signal red lights and a wind vane.
Sizing wasn’t easy. This location is tested by strong winds and snow/ice.

Aerial view of the lookout tower


The logs are, after 5m in height, connected by a steel joint to which a stiffening polygon/ triangle is attached. Also in these points, the individual rods are fixated. Horizontal and torsional forces are caught by steel cables fixated into bases located 15m away from the tower.

Held by steel cables, the observation tower is covered by safety glass


 

 


Larch itself is well resistant against weather conditions and furtherly a pressure impregnation is used, the wood isn’t in contact with soil moisture and joints are designed as drying, therefore we believe this tower should last at least 30 years.
