Sion Road runs alongside the grounds of York House and down towards the Thames and its passenger ferry. Nearby Sion Row is a terrace of several two-storey houses built in 1721 with a uniform cornice. Running parallel to the river is a line of houses from several periods, such as the Ferry House with its two floors of white stucco (imitation marble) and its slate roof, and Riverside House, a rambling structure beneath broad eaves.
