As a possible response to the dawning of a new „gründerzeit“ age, Aspern will see the creation of a new city covering 240 hectares including a lake for 20,000 residents and 20,000 working people within the next twenty years. One logical reason for this is that people can reach the city centres of Vienna and Bratislava in just 15 minutes. Naturally, such an undertaking requires strong identification points right from the start, and architecture can contribute hugely in that sense. This is where Slim City comes in. Thirteen slender towers of different heights form a unique and independent quarter on the construction site – a City in the city, as it were. Open urban space lavishly spread between the buildings is something that is more common in cities that have grown over time: a series of different plazas and constrictions – similar, yet varied, public, yet also used privately – which people can just walk through or use in many different ways. Although precisely calculated, these buildings appear to have grown by chance. They form units comprising 2 to 3 buildings linked together by exterior elevated walkways, which have the same address as the street from which they are accessible from. Consisting of 178 dwellings in all, these buildings obey a whole canon of formative rules. While standard floor plans prevail as long as external conditions remain more or less the same, new circumstances require an immediate response in the form of new floor plans. The ground floor gradually becomes a space for general use, instead of just for living purposes by introducing unusual living designs, small offices, commercial street use, a cafeteria-cum-party basement and a spacious community room with FM services.
