No. 6 And Attached Railings

This is a three-storey, attic, and basement house, now converted into flats, dating to circa 1786, with 19th and 20th-century alterations. It is attributed to John Palmer. The front of the house is faced with limestone ashlar, while the lower part of the basement and the rear are constructed of rubble. The roof is a double-pile mansard roof covered with Welsh slate, featuring two ashlar stacks with early clay pots on a coped party wall. A staircase is located to the rear.

The front elevation has a tripartite-window design. The first floor features three plate glass, horned sash windows, slightly narrower on the left and right. The second floor has a similar six/six horned sash flanked by plate glass sashes in plain reveals, with a continuous 19th-century timber blind box. The ground floor incorporates three plate glass, horned sashes, grouped similarly in plain reveals with a continuous stone sill. A round-headed shallow recess centres the ground floor, creating a quasi-Venetian window design. To the right is a similar shallow recess for the door. A six-panel door with flush beaded, fielded, and glazed panels is set within a bevelled, plain reveal and is accessed via a single pennant step and a paved crossover flush with the pavement. Two six/six sashes with wrought iron window guards are located to the left, above a crossover infilled with ashlar. A projecting section with a plank door and a small window is positioned above the crossover, sheltered by a stone-paved roof. Limestone area steps with pennant insets and a wrought iron handrail lead up to the front door. There are 20th-century windows within double dormers. Weathered sill bands are present on both the first and second floors. A moulded eaves cornice and coped parapet share a lead hopperhead with number 7 Burlington Street to the left. The rear elevation has six/six sash windows; the first-floor windows are fitted with wrought iron balconettes. A one-and-a-half-storey extension, clad in asbestos, is attached to the staircase and features a six/six sash window to the first half landing. A lead hopperhead is present at the eaves to the right of the extension. The interior was not inspected at the time of listing.

Attached wrought iron railings and a gate, with urn tops on limestone bases, adjoin the crossover to the left at a splayed angle. The house was developed in conjunction with Portland Place by John Hensley; related properties include numbers 12-15 Burlington Street and numbers 1-4 and 17-20 Portland Place. The East side of Burlington Street was part of a leasehold agreement from the Morford's Estate, and building leases were issued in 1785. The freehold land was conveyed to Hensley and William Phillips in 1772 and then transferred by lease and release to Daniel Tanner.
