In the fourth chapter, which is presented during the summer months, it is the turn of the Antwerp artist-architect Luc Deleu (°1944, Duffel). In 1966, Deleu received his architect's diploma but soon distanced himself from the world of architecture, which he thought to be set in its ways.

With his sometimes ironic and sometimes highly committed Proposals, Advice and recent projects, he comments on existing situations by formulating alternatives for them. In addition, he experiments with scale, perspective and volume: at first rather modestly with Lego brick constructions, later by way of monumental works with transport containers as building bricks. 

The works of art from the collection which are exhibited alongside Luc Deleu’s work and actually serve as a kind of context for that work, were selected in consultation with the artist. It includes work by Vito Acconci, Dennis Adams, Guillaume Bijl, James Lee Byars, Anne Decock Van Raef, Robert Filliou, Dan Flavin, Filip Francis, Jef Geys, Tina Gillen, John Körmeling, Wolfgang Laib, Gordon Matta-Clark, Guy Mees, Pieter Laurens Mol, Maurizio Nannucci, Maria Nordman, Panamarenko, Michelangelo Pistoletto, Guy Rombouts, Nicolas Uriburi, Philippe Van Snick, Marijke Van Warmerdam, Ben Vautier and Marthe Wéry.
