Abstract
The overall human progress continuously stimulates the transformation of the notion of architecture and enhances the development of new architectural forms. In line with the thesis that only sustainable architecture allows the fulfilment of contemporary requirements to full extent, this paper explores the variety of developed mobile educational spaces, classifies them into types and analyses their sustainability aspects. The analysis aims to define the cases and needs to which mobile educational spaces respond best, i.e. according to which their utilization is justifiable. The results open a new research debate on the relationship between sustainability and the duration of utilization.
