Pheasant Court, Frenkendorf
2021
In Frenkendorf, the first four-story column-and-slab structure made of wood was built. Thanks to TS3, the building once planned in concrete can be built in wood. The planning with the multi-axial load-bearing cross laminated timber panels is similar to reinforced concrete.
The project
The four-story residential development with 15 comfortable
comfortable apartments is located in Frenkendorf in Basel-Land.
The sustainably constructed timber building is
the highest building to date in which TS3 technology has been used. The
means that the floor slabs are made of large-format cut-to-size
cross-laminated timber panels, which are connected to each other on the face using TS3 technology.

be erected.
The construction
The Fasanenhof is a column-and-slab construction
construction as it is known from steel-concrete - simply made of cross-laminated timber plats
and with round wooden columns. This allows for a faster construction time, since no
drying is necessary. Only the staircase core was concreted. Here
the usual sequence was reversed: the wooden structure was erected first and later
erected first and later served as lost formwork for the liquid concrete.
liquid concrete.
The challenges
The cold
temperatures during the pouring of the CLT slabs necessitated winter construction measures. For this
the building was temporarily wrapped and heated. This ensured that the necessary
temperatures for casting and curing could be ensured.

The wooden ceiling becomes presentable
Wir Holzbauer, Issue 5.2022 – The beam ceiling is becoming flat: Researchers and engineers have found a solution for optimally replacing the concrete ceiling with wood. The first residential buildings have thus been realized and those involved are enthusiastic. (Report in German)
Wood instead of concrete, very simple
BlickPunkt, Issue 2/2021 - TS3 enables large areas to be made of wood. This means that wood can replace traditional reinforced concrete in many projects. In Frenkendor, the first four-story column-and-slab construction using TS3 technology is under construction. The people involved are enthusiastic.
"Design as in reinforced concrete, but build in wood"
Holz-Zentralblatt, Issue No. 1/2021 - The "Timber Structures 3.0" technology (TS3) of Timbatec Holzbauingenieure Schweiz AG enables biaxial load-bearing flat slabs made of wood with a column grid of up to 8x8m. This means that wood can be used in many construction projects in the same way as reinforced concrete. The special feature here is the blunt, face-side bonding of the timber components used. In Frenkendorf in Basel-Land (Switzerland), the first four-story building using TS3 technology is currently being built, the Fasanenhof apartment building with 15 apartments. (Report in German)
