Calvary Chapel, Regents Court and St John's Cloisters

Calvary Chapel, Regents Court, and St John's Cloisters is part of a former convent, now serving as a Pentecostal chapel and offices. It was built in 1860 by Edward Welby Pugin. The building is constructed of brick with blue brick patterning and ashlar dressings, topped with a slate roof, and is designed in the Decorated style.

The chapel features a two-storey, three-bay wing to the south, which connects to Kings House, and a north wing that has two storeys, a basement, an attic, and three bays, along with a return wing. The courtyard includes an entrance screen with a central segmental-pointed arch and flanking segmental-pointed entrances with overlights, topped by coping raised over the arch. The south wing has a lean-to extension at ground level, segmental-headed windows with four-pane sashes, and a stack in the roof slope; the rear is similar. To the left of the courtyard is a cloister with segmental-pointed arches featuring 20th-century glazing.

The south elevation of the chapel has three bays and an octagonal stair turret on the western side, adorned with a cogged frieze. The upper level contains two-light traceried windows and a pointed entrance in a projection. The turret is topped with a corbelled cornice and a slate spire that includes an open bell stage, along with stair lights and traceried lancets featuring a sill course and continuous hood. The west end showcases a rose window, while the east end is apsed with segmental-pointed windows, including casements at the lower level and two-light windows above. The north wing has buttresses and windows similar to those of the chapel, along with gabled half-dormers; it features a projecting two-storey bay with a rebuilt first floor. The return wing is similar but more utilitarian.

The inner courtyard to the north of the chapel has plain arcading on the returns. Inside, the chapel is located at first floor level and features an arch-braced roof, stalls along the sides, an enclosed balcony to the north, and a west gallery above the passage, with stained glass in the apsed end.
