Buildings are large, expensive to build, ecologically damaging, and tend to hang around for a lot longer than anticipated. Cities are formed by a messy and aesthetically undisciplined mass of old forms and redundant logics, yet the discipline of architecture rarely looks at the temporality of buildings over longer timeframes. The Grieving Pavilion studio subject asked students to design a number of buildings based on the following propositions: What happens if we take the ageing and wearing of materials seriously? How do we represent ageing and change in the drawing and representation of buildings? In what ways can we engage meaningfully with the fog of the future in the buildings we design today? The studio concluded in the design of one complete building to a detailed level. These design proposals aimed to demonstrate a sensitivity and intelligence towards temporality in buildings as the basic unit of the formation of cities over time.
