The people have moved in the TS3 multi-family house



The first four-story column-and-panel structure made of wood is located in Frenkendorf in Basel-Land. Such a structure is only possible with TS3 technology. Now the people have moved in - a review of an exciting construction project.

The construction industry is on the verge of a radical change: with a new technology, timber construction is conquering large buildings. TS3 makes large areas made of wood possible. This means that wood can replace traditional reinforced concrete in many projects - which is good for the climate. The technology is the result of over ten years of research and development together with the Bern University of Applied Sciences and ETH Zurich. With the four-story apartment building in Frenkendorf, the proof of concept has been more than provided.


TS3 technology is not only highly interesting from a technological point of view. It allows for use-flexible room concepts. Thanks to the load-bearing support, the walls are non-load-bearing and can be easily moved.


Thermal bridges made simple. Because of the low thermal conductivity of wood, there is no need for elaborate cantilever connections. The CLT ceiling simply runs from the apartment to the loggia.

Once the building was planned as a solid structure, then Andreas Scherrer of schererarchitekten ag was able to convince the client to build with wood using TS3 technology. During the convincing phase he had to plan the building project further in different material variants. There TS3 played into his hands. Because: The planning with the biaxial load-bearing cross laminated timber panels is similar to projects made of reinforced concrete. But the environment is happy: With the system change from concrete to wood, 536 tons of CO₂ could be saved at Fasanenhof. That is an important contribution to climate protection.

Easy application during construction  

"It doesn't affect us much with the TS joint. We can do our normal processes," explains Benjamin Kaiser, construction manager at Stamm AG. Thanks to the meticulous planning and prefabricated components, we set up the building with 15 apartments in just three weeks. Construction projects with a lot of steel, brick and concrete take much longer. Often, planning and decisions are still being made on the construction site. That massively disrupts the construction process. With timber buildings, it's different. Technologies such as TS3 and construction projects built almost exclusively from wood are worth their weight in gold for us, says Kaiser.

Die Brettsperrholzplatten wurden im Herstellungswerk vorbehandelt und sind einfach zu montieren.

The cross laminated timber panels were pre-treated in the manufacturing plant and are easy to assemble.

From research project to market maturity

Timber Structures 3.0 technology, or TS3 for short, is a process that can generate large surfaces from wood - without the cross beams that were previously common. These large areas can replace reinforced concrete in most areas. TS3 connects wood components on the face side. For decades, this was considered impossible. The solution is a two-component polyurethane casting resin. This resin connects the timber elements to each other on the face side. This enables column-and-plate constructions of the kind that were previously only possible with reinforced concrete projects. This means that timber construction has reached the third generation - a quantum leap that is causing the construction industry to rethink.
