25 St Mary's Street Including Garden And Boundary Walls

25 St Mary's Street is an early 19th century, two-storey and attic, three-bay simple Classical house located on St Mary's Street. The house features a central four-panel timber door with a five-light rectangular fanlight above, flanked by windows in the side bays, and has regular window placement on the first floor. There is a piended off-centre dormer in the attic. The street-facing elevation is made of squared and coursed sandstone, while the other elevations are constructed from rubble, with raised ashlar margins.

The windows are 12-pane timber sash and case, although the dormer has a uPVC replacement. The roof is covered with graded grey slates and includes a non-traditional rooflight on the rear elevation. The gable stacks are ashlar-coped with cans, and the skews are also ashlar-coped. The property has cast-iron rainwater goods.

In terms of the garden and boundary walls, there is a low coped section of wall with railings on the west (street elevation) and a high rubble semi-circular coped section of garden wall on the east.
