Papillon House, formerly known as Provident Place, 3-14 Balkerne Gardens

Papillon House, previously known as Provident Place, is a terrace of twelve dwellings built in the 18th century. The facade is constructed of grey gault brick with stucco rendering to the cornice and two door surrounds, and slate roofs. The rear elevation is of late 20th-century brick, partially rendered.

The earliest, central range was originally symmetrically arranged, comprising six units, each with a two-room plan and an entrance hall. The two-storey building has shallow hipped roofs to the east and west, with brick ridge stacks. The south-facing facade features a moulded, stucco-rendered cornice. The 5th and 6th bays, and the 10th and 11th bays, project slightly, bearing a stucco-rendered pediment atop pairs of plain brick pilasters. The ground-floor windows and door openings are arched with brick heads. The window openings are recessed, except within the pedimented bays, where the door openings have straight heads with a stucco render surround consisting of pilasters with moulded capitals, beneath a slightly projecting flat hood. The first-floor window openings have straight, segmented brick heads; the sash windows originally had three-over-six lights. Most of the entrance doors and approximately half of the windows are 20th-century replacements.

The late 20th-century rear elevation features full-height, staggered projecting bays and pent-roofed storage facilities, with shared entrances accessed by ramps and handrails. This rear elevation lacks architectural interest.

The interiors of three flats were inspected, and they have been extensively remodelled in the late 20th century, removing the original layout. This work included the insertion of shared lobbies and stairways, and the creation of one-bedroom apartments. The room divisions are largely late 20th-century partitions, and no 19th-century fixtures or fittings remain, such as fireplaces and joinery. While fragmentary elements of the historic structure survive, including the principal east-west wall, some cross-walls and first-floor chimney stacks, the interior is heavily altered and does not retain special interest.
