Aerial view from the south-west in early autumn sun, with the North Yorkshire coast, cliffs and sea beyond. A closed square ring of two-storey houses with slate roofs that step between sections, sandstone and white render walls, and charred timber corner blocks under pale zinc. In the middle, hidden from every side, the courtyard: a paved square with trees, a water bowl, the sunken lightwell and the trattoria's red striped awning. Two arched cart doors in the stone coach house on the east side open onto a gravel drive. Dry stone walls, a meadow and a few trees round it.
