Fasanenhof, Frenkendorf

2021

Line

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 Fasanenhof is a column-and-slab construction as known from steel-concrete - simply made of cross-laminated timber planks 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 challenges

The cold temperatures during the pouring of the CLT panels required winter construction measures. For this purpose, the building was temporarily wrapped and heated. This ensured the necessary temperatures for casting and curing.
