Description

This is a terraced town house located at 20 Old Queen Street, Westminster, built in 1909 by F.W. Troup. It is an individual Arts and Crafts interpretation of a neo-Georgian design, intended as a small town house. The building is constructed of dark red ceramic brick with stone dressings and a slate roof. It has three storeys, an attic, and a basement.

The front of the house is two windows wide, with three windows on the second floor. The ground floor has a low entrance to the right, featuring a panelled door with an oval leaded light, set within a stone surround with a cambered voussoir arch and console brackets to a serpentine cornice hood. A low, segmental arched casement window is located to the left. The first floor showcases two shallow, wood-framed, canted bay windows with glazing bar casements, set in semicircular arched recesses. Three small, segmental arched glazing bar sashes are found on the second floor. A bracketed eaves cornice runs along the top. A small, central Venetian dormer window is positioned in the attic. The front is complemented by good cast iron railings with urn finials and Portland stone panelled obelisk piers flanking the entrance.

The rear elevation, facing St James's Park, is red brick with stone quoins, featuring glazing bar sashes and a canted bay window on a smaller scale inspired by the adjacent 18th-century building’s design.
