Number 4, 5 and 6 and Attached Pump

Nos. 4, 5, and 6 Staple Inn, along with an attached water pump, are three terraced chambers located on the north side of a courtyard, formed by the rear of Nos. 337 and 338 High Holborn and Nos. 1-4 Holborn Bars. The buildings date back to around 1586 but were altered in the 18th century and refaced in brick in 1826. They were restored by Alfred Waterhouse around 1886 and underwent extensive reconstruction in 1937, likely by Stuart W Spiller, to preserve the north facades.

The structure is made of brown brick and features a moulded brick cornice at the second-floor level, along with a plain brick band at the first floor. The roof is tiled and includes dormers. The buildings rise four storeys, with attics and a semi-basement, and have a total of 12 windows. The doorway of No. 4 has a stone surround with a pulvinated frieze and an apron tablet above the centre, topped with a cornice and ball. The entrances to Nos. 5 and 6 are beneath an asymmetrically placed entrance arch from Holborn Bars, which has a rusticated surround and is topped by a plain stone band. Above this, there is a slightly projecting bay featuring a Venetian window on the first floor and a tripartite sash window on the second. The windows have gauged flat brick arches and flush frame sashes, and there is a parapet at the top.

The interiors have not been inspected, but the chambers are listed Grade I for their impressive Holborn fronts. Additionally, there is an attached water pump to No. 6, dated 1937, made of lead with a panelled design, a pediment, and a central spout surrounded by a quatrefoil. The base of the pump features three brick and stone steps that are bowed and shaped. Staple Inn has been part of the City of London since April 1, 1994.
