Stonehall Outpatients Clinic, St Mary Abbot'S Hospital

Stonehall Outpatients Clinic, part of St Mary Abbot's Hospital, is the central and male wing of the former Kensington workhouse, built in 1848 and designed by Thomas Allom. The building is constructed of red brick with white brick dressings and quoins, featuring blue and white brick diaper patterns, and stone finials and dressings on the loggia. It is designed in the Neo-Jacobean style and has a slate pitched roof that extends to the eaves.

The central section consists of seven main bays, with the second and sixth bays projecting further to full height beneath decorative gables topped with stone finials. To the left of the center, there is a wing with six main bays, the outermost of which also projects to full height under a decorative gable with a stone finial. There is a smaller, one-storey, three-bay wing to the left of this.

The central block has four storeys, while the wing has three storeys. The ground floor features arcading between the wings, which is set in front of the facade of the center, with a balustraded parapet above that is flush with the facade of the wing. The entrance is located at the center of the central block within the arcade. The windows are square-headed with gauged brick heads, consisting of three lights in the gabled projections and two lights between them. Many of the windows in the central block retain their original iron lattice glazing bars and small panes, while others have plate glass casements.

There are also projecting canted bay windows that rise through the ground and first floors to the gabled projections in the central block. The center bay of the central block projects slightly forward and features an inset clock within a decorative gable at the roof level. A small bellcote with a bell sits at the crest of the roof. This building is one of the earliest surviving examples of a London workhouse.
