'Kleinste Fabrik der Welt' (smallest factory in the world) produces environmentally-friendly homes

Thanks to the use of innovative environmental technologies, the Weissenseer timber construction company produces high quality passive houses – in a high quality passive house. Originally a traditional carpenter, Weissenseer has recently specialised in the production of wooden passive houses, which now makes up almost 90% of the company's activity. The 'Smallest factory in the world' project created a novel production process: a new production line, manufactured according to passive house standards, which would streamline and automatise the construction of passive houses.


As a result of the project, manufacturing times for a passive house, from raw material delivery to shipping of the components, has been reduced from an average of 20 working days to just 2-4 days of production time. This was achieved through the development of a highly efficient production chain, which is largely automatised and optimised according to time and space criteria. The 'Smallest factory in the world' has a capacity of 150 to 170 standard passive houses per year.Besides being a production hall, the 'Smallest factory in the world' is also a passive house itself. Very little additional heating is needed, as the heat generated by the machines is sufficient to keep the factory warm. Furthermore, about a sixth of the building is made up of office space, including recreation areas and a café.The factory now serves as a model for different utility buildings Weissenseer is intending to produce in the future, including office and commercial buildings, schools, and other public buildings. In addition to the knock-on effect for the region which was generated, the project also created several new jobs.
