Fasanenhof, 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 apartments is located in Frenkendorf in Basel-Land. The sustainably constructed 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 users maximum flexibility of use. Thanks to the prefabricated components and the precise planning, the entire building could be erected within only three weeks.
The construction
The Pheasant Court is a column-and-slab 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.
The challenge
The cold temperatures during the casting of the CLT panels necessitated winter construction measures. For this purpose, the building was temporarily wrapped and heated. This ensured the necessary temperatures for casting and curing.

BWSO Info
BWSO, December 2022 – Wood construction is a megatrend. More and more public and private developers are turning to wood as a building material because of its many advantages. Our vision is to build entire cities out of wood. Is that possible? And do we have enough wood to do it?
The wooden ceiling becomes presentable
Wir Holzbauer, Issue No. 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)
New dimensions
Immobilien Business, Issue No. 03/2022 – Timber construction: A new technology solves many of the problems previously associated with timber construction - opening up entirely new applications for wood as a building material. For example, in buildings with flexible uses. (Report in German)
Fasanenhof lighthouse project – Using wood instead of concrete to create a Minergie-P-multi-family house
Anzeiger Frenkendorf, Issue No. 15-2021 – This year, the Fasanenhof was the first Minergie-P-apartment building in Frenkendorf. What also makes this building a special lighthouse project is the climate-friendly and forward-looking use of wood instead of concrete. (Report in German)
Wood instead of concrete, quite simple
Immobilien im BlickPunkt, June 2021 – TS3 enables large areas made of wood. This means that wood can replace traditional reinforced concrete in many projects - which protects the climate and makes investors happy. In Frenkendorf in Basel-Land, the first four-story column-and-slab construction using TS3 technology is being built. The technology is proving its potential with the «Fasanenhof» apartment building with 15 apartments. The people involved are enthusiastic. (Report in German)
"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)
