Project description

Mobile concepts such as Tiny Houses (TH) are increasingly in the focus of the expert public and are discussed as novel solutions for housing and sustainability issues. High market prices in conventional construction support an increasingly high market density. These models are often planned as solitary units that are not stackable and miss the opportunity for efficient redensification of inner-city spaces. Stackability of modular building space can be achieved through new unit formats, but they often have limits in terms of sustainability. Research on three-dimensional architectures made of ecological building materials often has a permanent application in mind, despite their serial construction. These concepts are based on permanent supply connections and classic infrastructure. This raises the question of possibilities for self-sufficient supply structures for stackable technical building concepts.

With the current state of technology, it is possible to realise self-sufficient houses and neighbourhoods. However, mobile solutions for supply and disposal systems have only been implemented in smaller projects. Modern technologies of infrastructural and in-house supply and disposal offer diverse possibilities of combining functionality and sustainability to achieve ecological goals in housing construction. Modular mobile housing concepts such as temporary structures offer increased variability and adaptability due to their special design and thus expanded options for combining specific local, social and technical requirements with a wide range of possible solutions. According to the combination of technical concepts of water supply, wastewater disposal and heat recovery, different levels of sustainability, resilience and self-sufficiency can be achieved. Based on requirement criteria and their possible characteristics, the development of a modular component and system catalogue in the form of a guide for mobile housing is required.
