369 Pattern Buildings is an industrial construction system based on modular design for creating up to 7 floor wooden buildings of different typology and appearance. It is fit for designing and constructing buildings with a clear span of up to 8.5 m. A Pattern building can be a house, office, school, kindergarten, hospital etc. The 369 system has 3 basic module sizes - M3, M6, and M9.

Every Pattern Building is:

  • mass-customisable;
  • environmentally friendly;
  • made primarily of timber;
  • modular and prefabricated;
  • ready to be produced, assembled, and transported in most European countries



The 369 Pattern Building architecture must be informative. Its constructive and technical structure must be easily readable by the builder, the user and the maintainer of the building.


The 369 Pattern Building must be simple enough for it to be produced at different factories and assembled by different builders. The transport of modules must be legally and technically possible without special permits or escort to all regions of Europe by road, rail and water.

Environment friendly

The 369 Pattern Building needs a minimal amount of energy for production, transport and operation.


The components of 369 Pattern Building are easily accessible for disassembling and upgrading.


Given the growth cycle of wood used in construction, the main structures of the building must last for at least 100 years.


The modular system should not constrain design freedom and can be adapted to different typologies, providing only the technical means for achieving the design goals.


The 369 Pattern Building concept remains available without restrictions (see License) to anyone who wishes to develop it further.


Functional units of the building (for example, apartments in the case of an apartment building) should be independent of each other both in terms of access and in terms of utility systems.
