4, Castle Street

No. 4 Castle Street is a house built between 1723 and 1728 for James Brydges, Duke of Chandos, by the Duke's London surveyors, Benjamin Holloway or Fort and Shepherd. The building is constructed of Flemish-bond brick with a vertical joint to No. 1 Bond Street on the left, featuring painted stone architraves and a doorcase. It has a double Roman tile roof that continues with No. 1 Bond Street. The house has a double-depth plan and stands three storeys high with a two-window range. The second-floor windows have moulded segmental arches and are 6/6-pane sash windows with thick glazing bars, some of which contain crown glass. The other windows date from the mid-19th century and have two horizontal panes with margin panes in each sash. The six-panel door to the right has beaded edges on the panels, a moulded wooden architrave, and a hood supported by wrought-iron brackets. The ground floor has been noted as altered. The terraces of houses in Castle Street are significant as an important group, notable for their scale and ambition outside London's West End.
