36, Sackville Street W1

No. 36 Sackville Street is a terraced town house built around 1731-32 by Henry Flitcroft. It features a brown brick exterior and a slate roof, standing four storeys tall, with the attic added in the early 19th century, and includes a basement. The building is four windows wide, with the entrance located in the second bay from the left. The entrance has a moulded stone architrave flanked by narrow jambs and scrolled consoles supporting a cornice hood. The windows are recessed sash types without glazing bars, set under flat gauged arches. There is a plat band above the ground floor and a moulded stone cornice over the second floor, topped by a parapet with coping. Early 19th-century cast iron area railings are present. The front of this building shows a close resemblance to Nos. 9 to 10 St. James's Square, also designed by Flitcroft and built by Benjamin Timbrell.

Inside, although altered, the house retains several fine features likely designed by Flitcroft. The front hall includes a passage leading past the service stair to the main stairs at the back, with a closet beyond. The two-storey stair compartment is made of stone and features finely wrought iron balusters that closely resemble those found at No. 46 Berkeley Square. The principal surviving decoration is in the ground floor front room, which has enriched panelling and window and door architraves. Notably, the central doorcase is adorned with a carving of the mask of Aurora, draped with festoons above it.
