We see the entire urban landscape, in our example that of Hannover, as a potential host for our parasitic structure. We want to provide uncomplicated living space for homeless people and at the same time use our system to point out the larger problem and make the issue visible in the urban space for passers-by, residents and politics.
The remnants of the urban landscape are the livelihood of our temporary parasite. It sneezes its way into lifeless interstitial spaces and lingers until it finds a more attractive host or is forced to "relocate" by external factors. The structural concept is fundamentally based on the idea of prefabricated wooden building elements, which offer several advantages and, above all, enable rational and resource-efficient construction. In addition, it is important for the parasite to allow a smooth, uncomplicated assembly and disassembly! Especially in the cold winter months, we see the benefit of mobile, self-sufficient, parasitic systems that create living space for homeless people.
A fast, uncomplicated solution as an answer to the housing shortage in German cities is, in our opinion, a suitable field of application for parasitic structures in architecture.
The modules previously manufactured in the factory, based on a 62.5 extension grid, can be delivered and also connected to the timber support system floor by floor. Due to the typification of the construction principles, the elements can be quickly exchanged and extended. For example, the modules can be removed after a certain time and repaired at the factory. A double floor provides storage space and also serves as a sleeping area. Each module has its own wet room and can accommodate one person.
After both supports have been erected, the system scaffold is attached between them. The great advantage of the scaffold is that, on the one hand, it ensures bracing in the longitudinal direction as well as later access, but on the other hand, it also functions as site scaffold for assembly and dismantling.

The load-bearing structure and the rest of the components can be prefabricated in the factory, ensuring a high quality of work, optimization of costs, reduction of waste due to the elimination of fitting work, and reduction of assembly costs on site.The two glulam columns (24/24) form the structural and visual backbone of the design. They are the only load-bearing elements that touch the ground and are therefore the first components to be delivered and erected. At the heart of the columns is the steel console, which combines in one element connection points for the main beams, the scaffolding and the facade elements of the fixtures. The height of the bracket can be flexibly adjusted vertically by means of corresponding drill holes and can thus react to different terrain characteristics. In the base area, the brackets are bolted to the concrete base via a flat steel element.After both brackets have been erected, the system scaffold is attached between them.
The great advantage of the scaffold is that, on the one hand, it ensures bracing in the longitudinal direction and later access, but on the other hand it also functions as site scaffold for assembly and dismantling. The continuous main beams (12/24) are connected to the support at the holes provided by means of a steel dowel and span between the two firewalls of the existing structure, thus providing bracing in the transverse direction. In order to build in a resource-efficient manner, we decided to use a single continuous girder instead of the typical pincer construction. The secondary beams (8/24) can now be bolted between the main beams using T-shaped beam girders.
