Published by Estonian Center of Architecture and Lugemik on the occasion of the Estonian national exhibition “Interspace“ at the 14th International Architecture Exhibition – la Biennale di Venezia (6.06.–23.11.2014) “Interspace” investigates the spatial and social consequences of a data-driven society where personalised information flows produce a multitude of personalised readings of the collective sphere and thus, the role of public space is to be questioned. Accompanied by a new understanding about authorship and new techniques of design, this participatory model calls out for new ways of organising spaces. With regard to the changes that the last substantial structural transformation of the public – web 2.0 – has brought along in architecture, “Interspace” analyses what has architecture got to do with big data and what is the architects’ role at the time when their expertise is being challenged by digital technologies.
