With the world changing to a more sustainable society, the construction industry also wants to do its part and thereby build more carbon neutral. An alternative to the production of sustainable buildings is to relinquish from steel and concrete to focus on wooden building structure. This leads to major challenges for constructors both in terms of fire and the fact that wood has a low density compared to the previously mentioned materials. Purpose: The report will examine the problem of building tall buildings with a stabilizing body of cross-laminated timber (CLT) with focus on the coupling beam. Method: The work is based on a literature study done with credible electronic sources and industry facts, a number of manual calculations and results from the program FEM design. Result: The result was, as expected that the coupling beam failed to resist the loads from 22 storeys, but unexpectedly it could resist the loads from 13 storeys. Conclusions: The conclusion is that there are ways to have a satisfying section on 22 storeys by steel reinforcement or change the strength of the timber lamina. The section on the coupling beam from the report manage to hold for 13 storeys with the chosen parameters.
