10A, Vineyards

10A Vineyards is a building that serves as offices and a flat, constructed between 1765 and 1775. It was developed by Thomas Omer. The front is made of limestone ashlar, while the rear is not visible. The building features a parapeted mansard roof, with double Roman tiles on the upper slope and Welsh slate on the lower slope, also not visible from the rear. The gable wall is coped and has an ashlar stack with early clay pots to the right, and there is a shared ashlar stack with No. 10 Vineyards at the left end.

The exterior has three storeys and a two-window front. On the first floor, there are two six-over-six sash windows with plain reveals and stone sills, each with wrought iron balconettes. The second floor has two similar windows without balconettes. The ground floor features two similar sash windows in splayed reveals with stone sills, flanking a six-panel door that has flush beaded and fielded panels in a splayed reveal. There are also two single dormers with six-over-six sashes. The building has a band course over the ground floor, a coved eaves cornice, and a coped parapet. The rear elevation is not visible.

The interior has not been inspected. Historically, the land was owned by the Hayne family from 1638 when Thomas Hayne purchased it from William Snygge. It was inherited by Charles Hayne in 1750, who cleared it of a mortgage and other encumbrances. In 1756, plans to sell the Vineyards to Thomas Omer for building were advanced but were not finalized until an indenture on February 26, 1765, when Charles Hayne sold the Vineyards for building at a yearly rent of £50. Belmont was constructed on the west edge of the same land. The Vineyards functioned as a vineyard until around 1730 when the springs began to fail. The row to the north of Countess of Huntingdon's Chapel was originally called Harlequin Row due to the unusual combination of brick and stone used in its construction.
