Building sites are, by their nature, transitory. They’re a project set out for a defined period of time for a team of contractors to come in, complete, and leave. To fit in with that temporary view of the project as a whole, facilities are often treated in the same way. Rather than having purpose-built toilets, builders expect the plastic porcelain and gush of blue goop that goes with it. Similarly, instead of a café or kitchen that might be installed in an office for workers, contractors more often than not will be given a temporary fridge and a kettle; if they’re lucky they might even get a food truck.
