Volta House, Bolton House, Windmill Hill House and Enfield House

This is a terrace of four houses, originally three, built around 1720-30 and with a later addition. In the late 19th century, the facade was refaced in a Georgian style, and a fourth house, Enfield House, was added in the late 18th century. The houses are constructed of multi-coloured stock brick with red brick dressings, moulded brick bands, and brick pilasters marking the angles and the division between Bolton House and Windmill Hill House. They have tiled mansard roofs, each with a single dormer window.

The houses are three storeys high, with three windows each. Windmill Hill House has a full-height, three-window canted bay. Volta House and Bolton House both feature well-preserved doorcases with flat hoods supported by carved consoles, architraved doorways with fanlights (Volta House’s fanlight includes a lamp-holder), and panelled doors. Windmill Hill House has a mid-19th century stucco porch and an entrance on the east side within a lower, two-storey extension. The windows are flush framed sashes with gauged red brick flat arches and exposed boxing. The houses are topped with parapets.

The interiors were not inspected but are noted to contain good panelling and staircases with open strings, carved brackets, moulded handrails, turned balusters, and column newels.

Attached cast-iron railings with urn finials mark the forecourts.

Bolton House was the residence of Joanna Baillie, a Scottish writer, from 1791 to 1851, and was visited by poets Byron, Wordsworth, Keats, and Sir Walter Scott, as commemorated by a London County Council plaque.
