In recent years, timber construction has gained popularity in Switzerland and the rest of the world due to its sustainable and aesthetic characteristics. This enthusiasm for this style of construction requires a solid understanding of the functioning of this distinctive organic material. Current standards impose precise conditions on the design of such structures to ensure that they can withstand the stresses of the various loads applied, such as common vertical forces and extreme horizontal forces. This study is based on an existing project carried out in Australia, and presents an assessment of the feasibility of constructing an entirely timber variation in New Zealand, where seismic stresses are very high. The project, completed in a Sydney office, focuses on the development of an external bracing system adapted to local standards. A detailed 3D model was used to assess the structural integrity and seismic resistance of the proposed timber building. This study focuses on the challenges posed by the design and stabilisation of high-rise timber structures subjected to extreme horizontal loads. The results highlight not only the technical feasibility of constructing such a building but also the associated complexities and computational costs. The absence of reinforced concrete elements at the heart of the structure implies a highly flexible structure, providing the overall complexity of the project. While the study demonstrates the viability of an eight-storey timber building in New Zealand, it also highlights the need for meticulous planning and detailing due to the unique chal-lenges posed by seismic activity. Issues relating to conventional vertical design and fire management of the structure are also explored in detail. The project has provided valuable insights into the technical and logistical aspects of designing tall timber structures in seismic regions, contributing to a growing body of knowledge in sustainable construction practices.
