I live in a ‘2up/2down’ granite cottage in Speyside, Scotland. It was built for the workers at the local distillery (Ben Rinnes 1826). In pre computer days it took a couple of dozen people to run a distillery; it was a family unit and housing was provided close by. My distillery cottage was modernised in the sixties, when a separate kitchen and bathroom were added to the back of the house. Other than that nothing has changed for decades.
