Alltan Donn House, Altonburn Road, Nairn

Alltan Donn House is a large suburban villa located on Altonburn Road in Nairn. It was commissioned in 1898 for a client named Brebner and completed in 1906. The house exhibits an Edwardian style with a slightly English Caroline character, featuring a deep projecting timber cornice, dormers, and large piended and platformed slated roofs. The structure is built of rock-faced ashlar with dressed ashlar detailing, and it has timber casement windows with multi-paned upper panels.

In the 1920s, the attic accommodation was extended to provide additional bedrooms, and flat-roofed dormers were added at this time. The house has corniced ashlar stacks. The main entrance is located in a giant-pilastered center bay on the symmetrical southwest front, topped with a pediment. It features an arched doorway with a corniced architrave and keystone, leading to a large twin-leafed panelled timber door with a semi-circular tear-drop fanlight. Flanking the ground floor are box windows that light the principal rooms, likely the dining and drawing rooms.

The near-identical three-bay side elevations each have a box window, with the northwest side containing a French window. A tall staircase bay is centrally located at the rear and features a Venetian stair window. There is an adjoining L-plan basement and one-and-a-half-storey servants' wing to the northeast, which has piended dormer windows that break over the hanging eaves. The house retains some original timber sash and case windows with upper multi-pane panels. The servants' wing was divided into three separate dwellings in the late 1970s.

Inside, the layout is generously scaled, with an impressive full-height timber staircase at the far end of the entrance hall, illuminated by stained glass windows and a cupola. The interior features exposed timber floorboards, window surrounds, and architraved and lugged doorpieces with twin-leaf panelled doors. The servants' wing has been modernised.
