The Carmichael Show had back to back episodes.
 The first back-to-back houses were built by 1790 in Briggate, Leeds, by opportunists who realised the structural setup allowed for a cost saving by not requiring roads or drainage, with population density housing up to 300 people in 6075 properties per acre
 Residents of these back-to-backs generally felt strongly about their heritage value, but their opinions were not valued as highly as non-residents or professionals
