1-4, UPPER HARLEY STREET NW1 (See details for further address information)

Nos 1 to 4 Upper Harley Street are linked pairs of townhouses built in 1824 by John Nash as part of his Regent's Park Crown Estate development. The houses are constructed of stucco with a channelled ground floor and feature slate roofs. They are a balanced composition, dressed with an Ionic pilaster order, and consist of four storeys, including an attic storey, above a basement, with single-storey links connecting them and two entrances. Each pair has a three-window wide front, with the centre window being blind. The doorways are adorned with Ionic columns, with a porch at the return of No 1 and another in antis at the return of No 4. The windows have recessed glazing bar sashes, and the first and second floors are articulated by shallow Greek Ionic giant pilasters. There is a sill band at the first floor and a main entablature supported by the pilasters, along with an attic cornice and a blocking course. The first-floor windows are fitted with geometric patterned cast iron balconettes, and there are spear head cast iron area railings. Upper Harley Street was originally known as Brunswick Place.
