House W

This residential house reflects the trend of monolithic construction in modern timber construction and shows that tradition and new developments can be combined without contradiction. The concept of monolithic construction is consistently applied in this project not only in detail but also in the exterior and interior design, creating a coherent design as an example of modern living with traditional roots.

As a prototype for a new timber construction system of the company Stora Enso, it is determined by glued cross laminated timber (CLT) elements. A two-story building without a basement was created. In total, only six people were needed to erect the shell of the building with prefabricated elements. Within four days, the building was airtight.

Following the traditional timber construction, a gable roof is used. The typical protruding rafters were connected and thus concealed with the help of the front façade (spacing between 70 cm and 130 cm). The lamellas of the front façade protect the actual exterior wall from rain and other weather influences and are therefore part of the structural wood protection. At 28 cm, the exterior walls appear relatively thin and yet achieve a U-value of 0.36 W/m²K. In combination with additional cellulose insulation, even a U-value of 0.12 W/m²K is possible in the roof area. (Tim Lüking)
