Claremont Grove, 21 Claremont

This is a late 19th-century, two-storey, three-bay classical villa, located at 21 Claremont Grove, with a 1913 neo-Georgian extension designed by William Kerr of John Melvin and Son to the northwest. The house has a further, two- to three-storey, five-bay neo-Georgian block, with an extension to the southeast and a single-storey bay. A gabled, projecting polygonal stair tower is prominent on the northwest side. The building is constructed from squared, stugged grey sandstone with ashlar dressings, the stair tower being entirely ashlar. Features include a base course, eaves cornice, raised long and short quoins, raised corniced and lugged window surrounds, and a segmental-headed Ionic doorpiece.

The principal (northeast) elevation is three bays and symmetrical in its original section. A corniced ashlar central entrance porch has a doorpiece with plain-shafted Ionic columns, an open segmental pediment, and ovoid finials, leading to a timber-panelled door with a tall window above. A later gable-fronted, canted bay extension features a small ground-floor window, rectangular windows to the first and second floors, and bullseye windows in the attic. A screen wall extends to the northwest, incorporating a round-arched doorway, with a single window on the single-storey bay.

The southwest (garden) elevation features canted single bays with polygonal roofs to the outer bays of the main three-bay block. The later block has a tripartite window to the ground floor, a bracketed canted oriel window with recessed aprons to the first floor, and a bipartite window above. A timber and iron conservatory with a polygonal end projects to the southwest.

The interior features a parquet-floored, oak-panelled entrance hall, complete with a lugged stone fireplace and a false-beamed ceiling with decorative plaster panels depicting floral and plant motifs. Stone and marble fireplaces are found in the main reception rooms. Glazed timber doors have leaded margins, and there is a glazed tile kitchen. Built-in furniture is incorporated into the scullery, butler's pantry, and upstairs corridor. A stone-floored heated conservatory includes cast iron shelving from Mackenzie and Moncur Ltd.

Windows are predominantly timber sash and case, with 12-pane, 15-pane, and 18-pane glazing to the front elevation, and 4-pane and plate glass to the garden front. The roof is pitched and covered in graded grey slates, with corniced wallhead stacks topped with circular clay cans.

Outbuildings are flat-roofed and stone-built to the northwest. A square-plan brick and timber summerhouse features multi-paned Diocletian windows and a pitched clay tile roof. Stone rubble boundary walls have flat copes and square-plan ashlar gatepiers. A stone rubble terrace wall is adjacent to the southwest of the house, leading to a quatrefoil-plan pond in the center of the garden, and a Japanese garden with a tiered concrete pond at the bottom of the garden.
