Luegisland Apartment Block

Housing Construction, Zurich

The Luegisland apartment block in Zurich-Schwamendingen demonstrates how sustainable housing can be efficiently realised using innovative timber construction solutions. The five-storey building was designed by Oxid Architektur GmbH and comprises 34 flats. The clear layout of the building creates private retreat areas and ensures optimal natural light in the flats. For the timber construction, THEURL supplied a total of 740 m³ of CLT ceiling elements in IndustriePlus quality. In addition, some elements were delivered to the site pre-clad with Fermacell boards and pre-assembled. The high degree of prefabrication enabled precise execution and an efficient construction process.

TS3 connection: Large spans using sustainable timber construction technology

A particular highlight of the project is the connection of the CLT ceiling elements using TS3 technology. In total, more than 800 metres of joints were filled. The necessary pre-treatment of the TS3 joints was carried out at THEURL’s factory. The final joint filling was then carried out by TS3 directly on site. This combination of industrial prefabrication and innovative joining technology ensured that the project’s requirements were met to the highest standard.

Why TS3 for the Luegisland project?

TS3 opens up new possibilities, particularly in multi-storey residential construction: the technology enables biaxially loaded timber floors with large support grids of up to 8 x 8 metres. This results in flexible floor plans without intrusive joists – a key advantage for buildings that need to be adaptable in the long term.

For the Luegisland replacement development, it was particularly significant that TS3:

enables large spans to be achieved using timber, thereby reducing the use of resource-intensive materials
creates slim floor structures and gains valuable headroom
ensures a high degree of flexibility of use throughout the building’s entire lifespan

Furthermore, TS3 technology supports the project’s sustainable approach: timber stores CO₂, is derived from a renewable raw material and, thanks to prefabrication, enables rapid and efficient construction.

A project that builds the future on wood

The Luegisland project combines sustainable architecture, efficient processes and innovative timber construction technology. Through the combination of CLT floor elements, precise prefabrication and the TS3 connection, the result is future-proof buildings characterised by high quality, flexibility and resource efficiency.
