The study of human space in architecture has always been central to the discipline, and the design of spaces which combine architectural quality with habitability is even more relevant in contexts where the host environment presents extreme conditions. The paper aims to broaden this perspective to include architecture for harsh environments, with a particular focus on space habitats - both orbital and planetary. What is the current state-of-the-art? What measures are being taken in the design process to ensure the psycho-physical well-being of the inhabitants? What role can architects and architecture play in addressing this necessity? In the light of these questions, the intention is to investigate design proposals for orbital and planetary habitats, as well as settlements and outposts, to be able to extend the considerations to questions of urban planning and the organisation of space cities. Furthermore, is it still appropriate to refer to a city, or should it be more accurately described as an aggregation of architectures? According to this, considerations have been made as to which housing models should be applied in space, which characteristics of dwellings and terrestrial urban fabrics should be preserved, and which strategies should be implemented, given the unique and extreme conditions of the environment in which they are designed. In conclusion, this paper aims to initiate a process of consideration of the relationship between humans and architecture in contexts beyond Earth while maintaining a bilateral relationship with it.
