Trinity Building

Trinity Building is a non-conformist church with associated house and school, built in 1895 by Marshall and Dick. It is currently in use as a Polytechnic building. The building is constructed of snecked sandstone with ashlar dressings and has a graduated Lakeland slate roof with red ridge tiles and finials. It is aligned north-south and features a ritual north-west tower and a low south-west tower, flanking a west porch. The main body consists of a four-bay aisled nave, high transepts, and a chancel. The design is in the Perpendicular style.

The open-arched porch contains four small chamfered windows beneath a drip string and is topped with a shaped parapet. A deep splay is present on the arch, and a four-centred-arched door is set into a three-stage tower. The tower features small high slits, paired segmental-headed belfry openings, shaped battlements with corner pinnacles, and shallow set-back buttresses. The south-west tower has paired square-headed windows with tracery, a high parapet, and a pyramidal roof with finial. The set-back west gable incorporates a buttressed central projection with a six-light window. Paired windows are situated in the two-storey aisles, alongside a three-light clerestory and four-light transept windows.

The interior has painted plaster walls and a hammer-beam roof. A cantilevered gallery is present on three sides, with corridors running along the aisles. A high sanctuary arch defines the chancel. The west window contains high-quality glass by Atkinson Bros. of Newcastle, and other good pictorial glass can be found in the north aisle and north transept.

A two-storey, two-bay house is located to the rear of the church, featuring a half-timbered upper floor. Adjacent to this is a two-storey, ten-bay school building with wood-mullioned-and-transomed windows, with three windows set within gabled half-dormers.
