Lodge And Gatepiers, Garden Wall, Allerly House Including Stable Block, Gattonside

The Lodge and Gatepiers, Garden Wall, and Stable Block of Allerly House in Gattonside were designed by John Smith of Darnick in 1823, with later additions. This is a 2-storey and basement, 3-bay rectangular-plan Classical house featuring tripartite windows set in tall relieving arches on the ground floor and a shallow piended roof. The exterior is finished in buff-coloured coursed ashlar, with a base course and string course. The front has regular fenestration, while the rear is more irregular. A glazed timber porch with a pierced parapet leads to a single-leaf, 6-panelled timber front door, which is flanked by astragalled sidelights and a fanlight. A large triple-arched conservatory-style window is located on the west elevation. There is also a mid-20th century, lower 2-storey flat-roofed addition and garage on the east side.

The windows are predominantly timber sash and case with 12-pane glazing. The building features a pair of coped and corniced ridge stacks with octagonal clay cans, a grey slate roof, and cast-iron rainwater goods.

Inside, there is a central vestibule and staircase hall with a patterned tile floor that provides access to the public rooms. To the right is a bow-ended dining room, and to the left is a drawing room, both featuring marbled timber fireplaces. A long stone stair with a quarter-turn at the upper level leads to an open-well landing on the first floor, with a narrow mahogany handrail and pierced iron balusters. Above is a val cupola. The principal ground floor rooms are adorned with beaded timber panelling, some original plasterwork, and 6-panel timber doors.

The stable block is a single-storey structure built of whinstone with red sandstone ashlar dressings to the north, forming a courtyard behind the house. It features a central high pedimented archway, now fitted with a timber slated double door, along with a stable door to the left and a window to the outer left.

The garden wall is a curving rubble structure located to the west of the house, with a garden room at the northeast corner that includes a Gothic window.

The lodge and gatepiers are well-detailed, consisting of a single-storey whinstone rubble lodge with overhanging gabled eaves that have bargeboarding and timber pendentives. The south elevation features a canted window. The windows are predominantly timber sash and case with 8-pane glazing. The square-plan ashlar gatepiers have chamfered angles and pyramidal caps, and there are decorative cast-iron gates.
