Aldo and Hannie van Eyck met as students of architecture and later married. They collaborated on a large number of projects for the town planning department in Amsterdam, before establishing a joint practice, A+H van Eyck Architechten BV in 1983. Kersten Geers is an architect and co-founder of the award-winning OFFICE Kersten Geers David Van Severen. Jelena Pancevac is an architect and researcher. Bas Princen is a photographer and artist, known particularly for his images of architecture. Everything Without Content is a new series of publications made by Kersten Geers, Joris Kritis and Jelena Pancevac. The name combines the titles of the two publication series-and generally, theoretical ideas-that we have previously been working on: Architecture Without Content that recorded academic work at EPF Lausanne, and Everything at USI Mendrisio, where Kersten Geers was heading the teaching studios. The number stands for the first book made in 2023, that is 23 - 1.
