The developers can get away with such things, because student housing doesn’t officially classify as housing. It falls into the murky category of “sui generis” (Latin for “of its own kind”). As it falls outside a specific use class, it doesn’t have to adhere to the usual standards associated with dwellings (class C3). Local authorities differ in the their approaches, but student accommodation is usually either treated as a hotel (C1) or residential institution (C2), the same category as care homes, hospitals and boarding schools. Due to their limited occupation, these building types are immune from many of the codes that govern residential dwellings – from space standards to daylight and acoustics. At the same time, crucially, the developer is exempt from providing any contribution towards affordable housing.
