120 St Stephen’s Green is one of a pair of houses on the west side of the square designed by Richard Castle to look from the exterior like a single unit. Following Castle’s death in 1751, the development was sold by his executors to Richard Thwaites who by 1764 had completed and leased the houses. No. 120 is the finer, and more intact of the two and contains some delicious rococo plasterwork such as that seen here reflected in a mirror over the first-floor saloon chimneypiece.
