Homes in Britain are built 21 metres apart to protect the privacy of woman in Edwardian times: “a bizarre hangover from 1902, originally intended to protect the modesty of Edwardian women. The urban designers Raymond Unwin and Barry Parker walked apart in a field until they could no longer see each other’s nipples through their shirts. The two men measured the distance between them to be 70ft (21 metres), and this became the distance that is still used today, 120 years later, to dictate how far apart many British homes should be built.”
