12, Trinity Street

No. 12 Trinity Street is a house in a row, dating from the mid to late 18th century, although some parts of the rear may be from the early 18th century. The front features Flemish bond brickwork, while the rear is constructed of squared stone, topped with an asbestos-cement slate roof. The property is situated on a slightly wedge-shaped site at the junction with Trinity Road and is set back from No. 1 Trinity Road. It has a high parapet front leading to a steep roof with a half-hip on the left side, and a narrow rear range with a hipped end.

The house has three storeys and an attic, with two windows on the front. The second floor features two-light casements with horizontal glazing bars, while the first floor has plain sash windows, all set within painted brick voussoirs. The ground floor includes a 20th-century steel casement window in plain surrounds beneath splayed painted brick voussoirs with two keystones. To the left, accessed by four stone steps, is a panelled door with a small transom light, set in a deep reveal and also featuring painted brick voussoirs with a keystone. A slight cornice is located under the blocking course, which is topped with a coped parapet.

To the right, in the recess next to the adjoining property, there is a lead down-pipe with a bold hopper-head and a series of fixing cleats. The left gable, which rises above No. 11, has a small two-light casement, and there is a brick stack on the right party wall. The rear wing has a narrow three-storey end wall in stone, with a single two-light casement on the first and second floors. The Royal Commission on the Historical Monuments of England entry notes that Nos. 11 and 12 are of three storeys and attics and originally had bow windows on the first floor, but it seems unlikely that this house had a first-floor bow. It is possible that the unusual double-keyed arch at the ground floor once covered a projecting element before being replaced with the steel casement. The interior has not been inspected.
