Our chosen site is located in the capital of Hungary, Budapest. This aviary-like structure was
built by an unknown architect in the last century – in a parasitic style – onto a narrow old

This provides an incredible panorama which includes the beautiful Gellért-Hill, and a full
view to the rivercoast.
It used to function as a nightclub which led to the discontentment of the neighbourhood. It
