If we omit Regulations that govern small buildings, i.e. D2(3), D15, D17 and schedules 6 and 7, then the remainder of Part D is generally a set of functional requirements, with technical standards set by deemed-to-satisfy documents which are produced, through BSI, by the profession itself. The exception, of course, is the section on ‘Accidental damage’.
