With TS3 technology, timber construction is conquering the large buildings and can replace traditional reinforced concrete in many projects. The Fasanenhof is a good example of this. Experience the currently largestTS3 multifamily house on a virtual house tour.
The four-story residential development with 15 comfortable apartments is located in Frenkendorf in Basel-Land. The sustainably built timber building is to date the highest building in which TS3 technology has been used. This means that the floor slabs consist of large-format cross-laminated timber panels that are connected to each other at the ends using TS3 technology. In addition to a pleasant indoor climate, this gives the building's users maximum flexibility of use.
The TS3 technology is the result of over ten years of research and development together with the Bern University of Applied Sciences and the ETH Zurich. With the four-story apartment building in Frenkendorf, the proof of concept has been more than achieved.
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.
The Pheasant Court is a column-and-panel construction as known from steel-concrete - simply made of cross-laminated timber panels and with round wooden columns. This allows for a faster construction time as no drying out is required. Only the staircase core was concreted. Here, however, the previously usual sequence was reversed: the wooden structure was erected first and later served as lost formwork for the liquid concrete.
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 construction, then Andreas Scherrer of schererarchitekten AG was able to convince the client of a timber construction with the 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. The environment is pleased: With the system change from concrete to wood, 536 tons of CO₂ could be saved at Fasanenhof. This makes an important contribution to climate protection.
Easy to use during construction
"It doesn't affect us much with the TS3 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 entirely of wood are worth their weight in gold for us, says Kaiser.

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