No.17 And Attached Railings

This is a house dating from approximately 1790 to 1793, with alterations made in the 19th and 20th centuries. It was designed by John Palmer. The front of the house is constructed from limestone ashlar, with a Welsh slate double-pile parapeted roof and a mansard front, extended to a full third floor at the rear. It features a brick stack with early clay pots to the front roof, and an ashlar and rendered stack to the rear, situated on a coped party wall on the left side. The staircase is now located at the front, likely originally being positioned at the rear.

The house is three stories high, with an attic and basement, and has a three-window frontage. The first floor has three 19th-century plate glass windows with horns, set in plain reveals and featuring wrought iron balconettes. The second floor has three six/six-pane sashes in plain reveals, while the ground floor has two 19th-century plate glass windows with horns, also in plain reveals, with stone sills on the left side. A six-panel door with beaded and raised and fielded panels, topped with a single-pane overlight in a plain reveal, is located to the right of the ground floor windows, accessible by a single step leading to a concreted crossover. The basement has one large and one small plate glass window with horns. An ashlar extension with a 20th-century door is included in the basement area to the left, along with 20th-century area steps. There are one double and one single dormer each with plate glass sashes. A band course above the ground floor acts as a sill band to the first-floor windows, and another sill band serves the second floor. Moulded eaves and a coped parapet, ramped down from the left end, complete the exterior. The rear elevation has glazing bar sashes on the ground, second, and third floors to the right, with pairs of plate glass windows with horns on the first, second, and third floors on the left. A 20th-century window is present on the ground floor left, and the first floor right has a 20th-century replacement window within the former door opening, featuring a splayed reveal and evidence of a tent-roofed verandah.

The interior has not been inspected. Attached wrought iron railings and a gate, with shaped heads on limestone bases, are also part of the property. The house was originally part of an incomplete development of St James's Square on land leased in 1790. The upper part of Park Street was begun according to John Palmer’s design, and later continued by John Pinch after 1808, though it was not completed. The street was formerly terminated by All Saints Chapel and was intended to be extended in a northwest direction as Regent Place.
