Alex Romer and Naïm Aït-Sidhoum define EXYZT's practice as one characterised by ‘transgressive forms’ and ‘construction devices’. They explain how this has come about through the studio's penchant for the loose conditions of leftover spaces – derelict urban sites or marginal spaces by the sides of roads and railway lines – which require the building of temporary structures in tight timetables on limited budgets.
