The fact that hybrid buildings can be interpreted as extremely condensed urban blocks, increasing the city’s density and contributing to its public realm, forms one of the key interests of this research. According to its European interpretation, the “ground scraper” is not only public because of the character of its plinth facing the street, but also due to its interior space, partly accessible to public. As such it potentially extends the city’s public domain, horizontally and vertically, into the building’s interior and links the public domain inside and outside. Basically it acts as a city within the city.
