PROOFFLab regularly invites a tandem of an architecture office and a design office, one Dutch and one foreign, to work out a theme for the PROOFFLab series. During Salone del Mobile 2013 in Milan, PROOFFLab presents work in progress by Studio Makkink & Bey and two projects by a tandem. Belgian collective jij’s (architects de vylder, vinck, taillieu and Serge Vandenhove) and Dutch designers Studio Maarten Kolk & Guus Kusters were asked to create a project that centrals around acoustics. Both teams took the idea of sound and space much further and focussed on how a space is experienced, on how to rearrange and disrupt a space.
