Achnagairn House

Achnagairn House is a large, U-plan house dating to circa 1800. It underwent substantial redesigning and extension in the Arts and Crafts style, likely between 1905 and 1910, with a further ballroom and rear service range added in 1912 by W. L. Carruthers, who was probably also responsible for the earlier alterations. The house is two and three storeys high, with harled exterior walls and tooled ashlar dressings.

The east entrance front has an asymmetrical design, featuring a deep, bowed projecting two-storey and attic porch. The porch has a round-headed doorway with keystones and Gibbsian detailing, leading to a double-leaf plank door. The south front is wide and symmetrical, with three storeys and seven bays, plus an additional angled bay to the west. The three central bays are flanked by advanced square, single bays topped with ogee roofs, and all are set within outer gabled bays. A hexagonal plaque bearing a coat of arms is positioned above the central garden entrance.

A long, rectangular, eight-bay ballroom was added to the northwest in 1912. This features an angle drum tower with a conical roof and regular transomed, mullioned windows. The north service range, also from 1912, includes a round-headed centre archway with long and short detailing. This range is characterised by casement windows, multi-pane glazing with some intersecting Gothic detailing in the upper lights, crowstopped gables, apex finials, corniced stacks, and slate roofs.

The interior entrance lobby leads to a large, south-facing, panelled stair hall with a chimney piece at each end. The drawing room contains an Adamesque chimney piece, paired Ionic columns supporting the ceiling, and an inglenook with a chimneypiece decorated with Dutch tiles. An ante-hall dating to 1912 connects the ballroom with the stair hall and features a fielded panelled dado and a pair of niches flanked by Ionic pilasters. The ballroom itself is panelled with a high, timber braced ceiling and a baronial chimneypiece bearing a monogram and coats of arms; it was added by Co. ldfield, whose monogram is carved on the chimney-piece. A reset datestone from 1663 is found in the library.
