Inverallt House, Shore Road, Shandon

The northwest garden pavilion at Inverallt, Shore Road, Shandon, dates from the earlier 19th century. It is a single-storey and attic, three-bay, symmetrical, rectangular-plan cottage. The building is constructed of rubble with painted ashlar sandstone dressings and margins on the main elevation, while the side elevations feature red sandstone margins. Notable architectural details include projecting eaves, a base course, and quoin strips.

On the southwest elevation, there are three bays with a deep-set central door, which is a four-panelled door with a painted blocked fanlight and an inner half-glazed door. Flanking windows and gabled dormerheads are symmetrically arranged. To the outer right, there is a modern wooden and glass flat-roofed conservatory. The southeast elevation features a flat-roofed conservatory at ground level and symmetrically disposed windows at the gablehead. The northwest elevation has a gable with a window at ground left and two symmetrically arranged windows at the gablehead. The building has twelve-lying-pane sash and case glazing, a grey slate roof, and rendered, coped apex stacks with octagonal terracotta cans.

The interior was not seen in 1993.

Additionally, there are circular-plan garden pavilions at either end of the sea boundary wall enclosing Inverallt and Inverallt Cottage. These pavilions are constructed of rubble with harl pointing, featuring timber eaves and conical slate roofs with lead finials. Each pavilion has a timber door and windows, including a two-leaf, half-glazed, round-headed door facing into the garden and round-headed timber casement windows facing the sea. The northwest pavilion is full-height and free-standing towards the sea, with walls that abut the sides at the garden elevation. The southeast pavilion is corbelled on the seaward elevation and projects more into the garden. The boundary wall is made of rubble with alternating flat and semicircular coping.

The site also includes substantial gatepiers made of rubble with harl pointing and plain pyramidal caps.
