chépas is Brussels slang, which stands for I don’t know, and points out the continuous indecisive condition of Brussels.

chépas collective is a multidisciplinary collective, founded in 2015 by Sebastiaan Willemen, an architect, and Lola Daels, a visual artist. Inspired by marginal spaces, urban or rural, they create interventions and performances in public space as well as in white cubes. Their work balances between poetry and criticism, rationalism and humour, activism and art, between now and the future. 

Sebastiaan obtained a master in architectural engineering at the VUB, Brussels and is an active urban designer for Suède36 architectes in Brussels. Besides his architectural work, Sebastiaan is developing an artistic practice in which he explores the boundaries of conventional urbanism, often through interventions and performances dealing with perception of space and spatial behavior.

Lola Daels graduated in fine arts at Sint-Lucas Brussels and has since then elaborated her artistic career during several exhibitions and residencies. Beside her work as an artist, she played an active role in the organization of multiple exhibitions, working for M-Museum Leuven and Contour Mechelen.


While the collective started with guerilla urbanism, they’ve been invited to participate in several exhibitions and residencies, in which they always adapted to the situation with temporary in-situ installations.
