One of the ( many ) attractions of the tiny property that we moved to in central France was the fact that it contains a bread oven. In fact, the bread oven was the main function of the building when constructed some time in the 16th or 17th century, to provide bread for the neighbouring farm, a common arrangement back then. The original building consists of the oven, a small room to access it and to prepare the dough, plus a room directly above. Compact and functional might be an appropriate way to describe the space.
