"The Form of Form" embodies the core exhibition of the 4th edition of the Lisbon Architecture Triennale. The curator, Diogo Seixas Lopes, challenged 3 architecture offices, Johnston Marklee (USA), Nuno Brandão Costa (Portugal) and OFFICE Kersten Geers & David Van Severen (Belgium) to jointly design and construct a reflection on form and authorship in architecture, functioning as a physical support for the contents compiled by Mariana Fabrizi and Fosco Lucarelli (Socks-Studio).

Over the course of almost two years of joint work and reflection, the exhibition project has evolved into an ephemeral construction. Constructed from the full-scale (1:1) reproduction of twelve spaces taken from projects and constructions of each of the offices. The choice of spaces was made by the three designers. They each selected two spaces from the other two participants. This process of choice is the essence of the process, expressed in its construction.
