The Orkney Islands are an archipelago of 70 islands off the north coast of Scotland. A popular destination in its own right, the archipelago also offers close access to historic sites like Skara Brae and Maes Howe, the latter considered one of the most important Neolithic sites in Europe. In total, approximately 20,000 people live on the islands year-round, with another 18,000 permanent residents choosing to spend their summers there. There are two key types of housing stock in Orkney. Most housing is either a traditional terraced house or an older, semi-detached two-storey house. Each of these has either been built with a stone or timber frame, and can be found all over most settlements across the islands. The reason for their popularity lies in how well they suit their landscape, providing durable and storm-proof living conditions.
