Jalmarintupa consists of 21 modules comprising a total floor area of 770 square metres. The frames of the modules were made with cross-laminated timber (CLT). After assembly in Finland at Stora Enso’s unit in Hartola, the modules were installation-ready and included all surface materials from window frames to mouldings.
Construction on Jalmarintupa started in August 2012 and it was ready for occupation by early December. Modular construction can, in fact, be up to three times faster than traditional element construction. The method also enhances the quality of the construction, as the modules are assembled exclusively indoors and thus never exposed to moisture at any stage of the construction process.
Stora Enso and Lakea, a developer owned by 15 Ostrobothnian municipalities, will build several modular wooden group homes in Finland in the near future.
