Belsize Park Underground Station including forecourt walls, gatepiers, gates and railings

Belsize Park Underground Station, constructed in the early 20th century, is a two-storey building with a symmetrical facade of five main bays arranged 1-3-1, incorporating alternating half-bays and a central triple arcade. The station’s structure utilizes a steel frame clad in brick, with the brickwork faced in ox-blood red faience manufactured by the Leeds Fireclay Co Ltd. Original entrances and exits are positioned in the penultimate bay to the north and the southernmost bay. An open passageway occupies the northernmost bay, while timber windows are found in the central and adjacent bays; the left-hand window is original, featuring moulded decoration to the transom corners, and the other is modern. The upper storey is characterized by timber Diocletian windows set within keyed semi-circular arches displaying egg-and-dart decoration. Cartouches are positioned between the springers of the central arcade, and deeply-hooded oeil-de-boeuf windows are present in each half-bay. Frieze lettering has been removed from the facade. The ticket hall has been extensively modernised, though replicated tiling referencing the 1906 pattern has been incorporated. A straight staircase leading to a spiral staircase retains original cream and green tiling, accompanied by a pomegranate frieze and a wooden handrail. Original dark red and cream tiling also persists within the spiral staircase. Lift portals feature curved, moulded architraves. Tiling in the lower passageways and platforms was renewed in 2008 to match the original design, with the exception of the soffit banding. A brass clock with an ornate bracket can be found on the southbound platform. Outside the station, a forecourt is enclosed by Portland stone gatepiers, cast-iron railings, and gates set upon a low stone wall; this is a unique feature among stations designed by Green. Exit gatepiers include 1920s bronzed poster frames with swan-neck lamp brackets.
