How will we live together?, the topic propesed by chief curator Hashim Sarkis, encourages exhibitors and visitors of the 17th International Architecture Exhibition to engage in broad dialogue. Our proposal focuses primarily on the question of living together with our built heritage and the experience of the layered spatial realities while pointing out the necessity of the act of reflection. Therefore the substantial and essential dialogue on these topics – taking place on different levels of the public – constitutes the central element of our proposal. The question is general, but the subject is concrete and the location has the capacity of being tangibly real. We regard the controversial reconstruction of former large-scale public buildings in the Buda Castle currently happening at this symbolic Hungarian location a process to be evaluated in the context of outstanding Buda Castle buildings and concepts of former decades.
