11, Winckley Street

No. 11 Winckley Street is a large townhouse, built in 1799 or 1800, and now serving as part of a college annex (linked to No. 5 Winckley Square). It was the first house constructed on Winckley Square, commissioned for William Cross, who conceived the square's design. The building is constructed of red brick in a Flemish bond pattern, with sandstone dressings and a slate roof. It has a rectangular, double-depth, double-fronted plan positioned on a corner site, featuring a gable facing Winckley Square.

The house consists of two main floors and an attic, with a cellar below, and has five bays with a symmetrical arrangement, except for the service door. It has an ashlar plinth, a band at the first floor level, a plain frieze, and a moulded cornice. The central doorway is round-headed, enclosed by a substantial doorcase with Tuscan pilasters, a plain frieze, and a prominent cornice with mutules and a blocking course. The door itself is panelled and sits within a wooden surround, accompanied by narrow side lights, a rectangular overlight, and a fanlight with margin panes of engraved and coloured glass, featuring anthemions in the band around the fanlight. A smaller, service doorway, with a moulded architrave and rectangular overlight is located immediately to the left of the main entrance.

The windows are mainly 12-pane sashes, although the ground floor windows to the left have been altered. First-floor windows are unhorned and have raised sills and wedge lintels. There are two cellar openings on each side, protected by grills. A single ridge chimney stack is present.

The gabled facade facing Winckley Square showcases five bays, with the first floor's central three bays slightly raised, and the gable treated as a pediment. The ground floor features tall sashes without glazing bars, while the first floor has 12-pane sashes. Three attic windows are incorporated, with the central window round-headed and featuring V-shaped glazing bars in the head.

Inside, the staircase has ornamental cast-iron balusters, but the interior has otherwise been altered.
