The ReSidence project is researching digital construction technologies for rapidly renewable resources and combining these into a modular construction method for temporary, completely recyclable and waste-free living space extensions. To this end, a construction method developed at FibR GmbH for load-bearing structures made of natural fiber composite is being further developed and research is being conducted into how this can be transferred to façade constructions. At the same time, research is being carried out into how a hybrid material system of willow/clay/wood composite developed jointly at KIT can be used for load-bearing wall and ceiling components. In a synergetic development of both construction methods, their interfaces are being researched and combined into a holistic, digitally prefabricated construction system made of natural building materials. The project maps the complete material cycle of the raw materials used and researches the extraction of natural raw materials, their combined use as hybrid components in the construction industry, their reusability and the recycling of such components. This requires coordinated innovations in the following areas: Agricultural management of wetlands, material characterization of natural hybrid material systems, digital process technology for processing inhomogeneous grown materials, integrative computer-based design processes, as well as the development of structural models and test procedures for the dimensioning and approval of such building systems. Following on from the ecological and climatic necessity of rewetting peatlands to bind Co2, agricultural methods are being tested to extract building materials from these peatlands and thus use them both ecologically and economically.

The modular reusability of the robotically prefabricated flax fiber facade structure and the willow-clay-wood wall and ceiling construction system will be tested in the overall system using the demonstrator construction at the Wangen State Garden Show. As part of the project, the IIP's Resource Management in the Built Environment research team will holistically record the resulting material flows in order to carry out a comprehensive LCA analysis on this basis. In addition to ecological considerations, economic factors of the construction method are also recorded in order to evaluate its transfer and market potential.
