– 4×4 the WOODEN PILOT

Flexibilty of construction, structure and function are essential points to ensure the longevity of a building.

“Good conversion potential and flexibility reduce the risk of vacancy and contribute in the long term to user acceptance, extension of service life and reduction of life cycle costs, i.e. the economic success of the property.”
(DGNB-Deutsche Gesellschaft für nachhaltiges Bauen; 2022)

The developed wooden construction kit system reacts to the challenges of the climate crisis. It requires less material in the life cycle (sufficiency), combines material-appropriate construction methods with an innovative energy system and reasonable floor plans (efficiency), and creates longlasting flexible room structures and components (consistency). The flexibility of the construction is ensured by an open supporting structure system and demountable superstructures. The construction principle of “screwing instead of gluing” creates scope for adaptations over the course of the building’s life cycle and avoids the waste that would otherwise be produced in the course of future adaptations. Balconies, terraces and external accesses are selfsupporting and are therefore structurally independent, which creates efficient building sequences and consistent constructions.

The modularity of the structure creates structural flexibility and at the same time enables spaceefficient and flexible floor plans. This offers the option of adapting the building to future usage requirements with comparatively little effort. This usage neutrality is strengthened by the reduction of loadbearing interior walls, clear shaft positioning that bundles sanitary and kitchen lines, and efficient wet room layouts.

The designed modular system is applicable to the diverse site configurations of a heterogeneous city like Vienna. In this competition, the plots in the 22nd district Naufahrtweg and Aspernstraße as well as in the 21st district Orasteig II were played with the modular system. Here is shown how the different building sizes XS, S, M, L and XL show function.
