New Construction of the Lido Hopfräben, Brunnen
2021
The entrance area of the Lido Brunnen has been redesigned. Large-format cross-laminated timber panels cover the entrance area. The use of TS3 technology for the end-joint grouting allows for a wide column spacing.
The Project
The popular Lido Hopfräben was showing its age, which is why the outdoor facilities underwent a comprehensive renovation. As part of this project, three cantilevered roofs using TS3 technology were constructed over the service and changing room buildings. An organically curved main roof accentuates the inviting entrance and provides shade for the restaurant’s seating area. The sustainable and cost-effective timber construction and the structured layout of the spaces ensure comfortable use and efficient operation.
The Construction Method
Thanks to the joint grouting on the front edges of the CLT panels, the roofs appear to float. The CLT panels rest on slender supports arranged in an 8x8-meter grid.
The Challenges
The beach pavilion roofs were poured in winter at low temperatures. Therefore, winter construction measures were implemented during the pouring process.
Construction data
- Number of floors: 1
- Gross floor area: 899 m²
