Archetypes features a recent series by Canadian artist David K. Ross, who works at the interface of photography, film, and installation. His images of architectural mock-ups, staged at night with dramatic lighting that isolates structures from their surroundings, demonstrate how these objects have become a charged form of proto-architecture. Built at full scale, these architectural fragments—to be removed from construction sites as buildings near completion—ensure that a project can be executed exactly to design, and they provide clients with a simulation of a building that leaves little space for speculation. The task of mock-up documentation is usually left to architects and contractors, who take quick snapshots for their reference during site visits. Archetypes is the first-ever photographic compilation of this type, reaching beyond a mere artistic record of building technologies and typologies. Instead, the book offers an effective platform to consider what it means to pre-construct fragments of buildings in all their complexity. Published alongside Ross’s images are four essays framing the historical, technological, and civic significance of the mock-up.
