In the late 1980s, national building regulations in many European countries restricted the use of timber frames for the construction of multi-storey buildings. Regulations that stipulated the choice of material in construction excluded wood, as a result of a number of devastating fires in cities at the end of the 19th century. As a consequence, no development of multi-storey timber housing took place and other materials such as steel and concrete were used. However, extensive research has shown that material-neutral building regulations are preferable and, for more than two decades, function-based regulations have now become common in many countries, and this has contributed to an increase in the construction of multi-storey timber buildings. In Scandinavia, as one example, the development since the mid-1990s of multi-storey timber buildings can be described as a success story, but there are also many other countries that show a positive development in timber construction. There is a great market potential for the use of wood in all types of buildings employing a combination of digital design and CNC processing. This paper gives an overview of the development of multi-storey timber building with a special focus on future trends such as the combination of digital design and flexible planning-design tools and CNC processing to design and build extraordinary constructions.
