Due to the increase in individualisation and in single households, the demand for small and affordable apartments is rising permanently, especially in metropolitan cities like London, Tokyo and New York. Thus the prices for rents and real estates are constantly going up as well. 'POLIS' takes the winning concept of the American 'Mobile Homes' and puts it into the centres of the urban cities. The company develops living units particularly for an urban space, which you then purchase and attach to docks of already built houses.
