31 Head Street, Beith

31 Head Street in Beith is a villa built around 1800, with some later alterations. It is a 2-storey and attic, 3-bay L-plan structure featuring a round stair tower at the rear and a single-storey rubble byre positioned at right angles to the back of the villa. The building has a base course, angle and window margins, an eaves course, and a moulded eaves cornice, along with straight skews that have scrolled skewputts. The façade is painted render, while the gables and rear are harled with exposed ashlar margins.

On the southwest (principal) elevation, there is a central modern door that is recessed and surrounded by a pilastered key-block arched surround. This is flanked by sets of bipartite windows on both the ground and first floors, with a central window on the first floor and three rooflights in the attic. The northeast (rear) elevation features a small, modern single-storey extension at the base of the stair tower and a modern picture window on the ground floor of the return gable.

The former byre is a long, low structure with a pitched roof made of random rubble, which includes large later 20th-century rooflights and blocked openings. The property has UPVC windows, along with two timber sash and case windows at the rear, one of which is an original 12-pane window in the stair tower. The roof is covered with grey slates in diminishing courses, and there are two remaining corniced ashlar gable stacks (without cans) and one replacement stack on the gable. Some lead rain-water guttering is present at the rear.

Inside, the villa has been altered, and there are no surviving chimneypieces. The central stair features an original cast-iron balustrade and a mahogany handrail, and there is a plain cornice in the upper hall. A turnpike stair leads up to the attic.
