If you turn round when you get up to the barbican, you will see the cottage built on the edge of the plateau, with the ladder still against the wall to provide access to the loft.
Originally, the chimneys were rather lower, but they had to be raised to meet modern building regulations. (A local architect tells me that this is not the only reason: the old low chimneys smoked a lot, depositing a film of tar on the inside of the roof which has helped to preserve the old timber - these days people prefer not to be smoked.)
