Design for reuse and recycling
By working with CLT, the supporting structure can also serve as the interior finish. For example, no flooring, suspended ceilings or plastering are applied, but the CLT is left exposed wherever possible. This ensures enormous material savings and a drastic reduction in material impact.
To keep the residual value of the CLT panels as high as possible, the pipes for lighting and electricity are assembled and the sanitary appliances are grouped in 1 unit. Thanks to this functional separation, technical installations can be adapted without damaging other parts of the building. In the central corridor, too, the main cabling is laid in a cable tray that is accessible and allows for easy extension or adjustments.
The structure of the facade can be completely disassembled with the option of recovering the wooden planks and insulation undamaged. The flat roof has a roof covering that has been loosely placed and ballasted, so that the insulation and the roof covering can be easily separated during disassembly later on. The units themselves rest on steel poles mounted on Stelcon slabs on stabilised ground. The foundations are therefore also very modular and can be disassembled with a high reuse potential. The walls that connect the modules to the central corridor can be regarded as the inner walls. These were provided in a timber-frame construction, with wooden panels as finish and a detachable threshold at the height of the doorway.
The lifting points of the modules have remained, but have been concealed in the roof finish. This makes it easy to disassemble the modules in their entirety later on. The CLT units themselves were assembled from CLT plates that were not glued but screwed together. This means that, if required, the units can also be taken apart with minimal damage to the panels.
