1, Dean Trench Street Sw1

No. 1 Dean Trench Street is a block of flats, now used as offices, built between 1951 and 1955 by architect H.S. Goodhart-Rendel. This building was constructed on the site of a house designed by Goodhart-Rendel in 1912 that had been destroyed by bombing. The structure is asymmetrical and made of red brick, featuring a long return elevation to Tufton Street. It stands four storeys high with a hipped roof that includes four dormers. The entrance front is three bays wide at the ground and first floors, with a single broad bay window on the second and third floors. The return front consists of four bays with two sets of bay windows, which are two and three storeys high. There are circular windows in the centre at the second and third floor levels. All windows are sashed and have small panes, showcasing an interesting post-war design in the style of Norman Shaw.

Additionally, the corner terrace house at No. 1 was built in 1913 by Goodhart-Rendel. It is constructed of red brick with a tiled roof and features a restrained and carefully balanced Free Style design that draws on themes from the late 17th century and early Georgian architecture. The building has four storeys and a dormered attic beneath a steeply pitched hipped roof. The front is three windows wide with irregular fenestration and a long four-bay return to Tufton Street. The doorway is located to the right and is small in scale, featuring a door with a central octagonal panel and very narrow sidelights beneath a shallow camber arched fanlight. There is one tripartite segmental arched window on the ground floor, three tall segmental arched windows on the first floor, and one regular tripartite bay window on the second and third floors. The return features two bold oriel bay windows, one two storeys high and the other three storeys high, along with two circular windows at the centre of the second and third floor levels. All windows are flush-framed sashes with small panes. The building has a boldly moulded wooden eaves cornice and hipped roof dormers aligned with the Tufton Street oriels. This property is part of a sensitive early 20th-century redevelopment of Dean Trench Street and the west side of Smith Square.
