Provisional constructions are ideas drawn in the ground with whatever is at hand. When intentional they are the best-laid schemes which aim to inform and evolve through word of mouth or participation. When unintentional they are constructions which neglect the reality of their design; the material lifespan and possible future re-use, for surely that site can only provisionally contain a building of that typology before its redundancy emerges. They are fields and vessels; provocative and potential.
