No. 9 and Attached Railings

No. 9 is a house dating from circa 1765-1775, with later alterations in the 19th century. It was developed by Thomas Omer and stands on land formerly owned by the Hayne family from 1638. The site was sold to Thomas Omer in 1765 for building, following earlier plans and the prior use of the land as a vineyard until around 1730 when its water springs failed.

The front of the house is limestone ashlar, with rubble below the basement windows, and has a double-pile, parapeted roof covered with Welsh slate to the front. The rear roof is not visible, and features a coped party wall to the left and ashlar stacks with early clay pots to the right. A shared front roof with No. 10 Vineyards exists.

The house is four storeys and has a basement, featuring a three-window front. The first floor has three nine/nine sash windows in splayed reveals, with lowered sills and wrought iron balconettes. The second floor has three six/six sash windows in splayed reveals with stone sills and guards. The third floor has two six/six sash windows in plain reveals, with a blind window in the centre. The ground floor has two six/six sash windows in splayed reveals with stone sills and wrought iron balconettes to the right, and a six-panel door with a flush fielded and single-glazed panel, set within a pedimented Doric doorcase with one Pennant step. The basement has a six/six sash window in a splayed reveal with a stone sill, and a two-pane overlight above a concrete-roofed extension area with a plank door, and another plank door beneath the front doorstep. The exterior detailing includes band courses over the ground and first floors, a moulded former eaves cornice over the second floor, a sill band to the third floor, a coved eaves cornice, and a coped parapet. The rear elevation is not visible.

The interior of the house has not been inspected. Attached to the front are wrought iron railings, with shaped heads and a bottom rail on buns. The row of houses north of the Countess of Huntingdon's Chapel was formerly known as Harlequin Row, owing to the unusual use of brick and stone in its construction.
