Project "Wooden Sphere Steinberg am See"

In 2019, a masterpiece of engineering opened its doors in Steinberg am See, Germany. The worldwide largest walkable wooden sphere (capacity for 900 visitors at a time) by inMotion Park Seenland GmbH is superlative in many ways. With a weight of over 500 tons, a height of 40 metres and a diameter of almost 50 metres, this project can already be seen from afar. 627 m³ of glued laminated timber, 190 tons of steel parts, 40,000 screws, 18,000 bolts/building screws/dowels, 3,300 m² cladding panels and 2,200 meters of railing - these are just a few of the key features of this enormous project.

Given the complexity of the supporting structure, the architecture itself and the requirements of structural wood protection, this unique project marks another milestone and a novelty in the project history of HESS TIMBER. The complex prefabrication as well as the subsequent preassembly and erection of the glued laminated timber elements has been one of the biggest challenges for all involved. We at HESS TIMBER are proud that we were able to demonstrate our knowledge and expertise in this extraordinary project.
