Hamilfield, 12 Kilwinning Road, Irvine

Hamilfield is an earlier 19th century, two-storey, three-bay classical house located at 12 Kilwinning Road in Irvine. It features single-storey, one-bay flanking pavilion wings and is constructed of painted, stugged ashlar with a base course, eaves band, cornice, and a raised wallhead at the centre of the west, south, and north elevations, with pilaster ends.

On the west elevation, which is the principal facade, there is a central entrance with a modern door and a semi-circular fanlight. This entrance is recessed and framed by a pilastered, corniced doorpiece, with a window centered above it on the first floor. The flanking bays contain windows on both the ground and first floors. To the left is a trompe l'oeil single-storey wing that functions as a screen wall with a blind window.

The south elevation features an advanced flanking wing and a garden screen wall abutting it, with a window on the right at the ground floor of the main house. The north elevation has a modern flat-roofed double garage at ground floor level, with a garden screen wall abutting to the right.

On the east elevation, there is a harled single-storey addition built against the centre and right bays, with a piended roof that partially obscures the staircase window in the centre bay. The left side has windows at ground floor, and there are surviving windows at first floor on both the left and right. A modern bay window is present in the single-storey wing to the left, and a harled full-height exterior stack has been added to the right.

The house has varied 12-pane timber sash and case windows alongside modern windows, with a grey slate piended roof and central ashlar wall head stacks on the north and south. The single-storey wing has a piended, felted roof.

The interior was not seen in 1997.

There are outbuildings and boundary walls associated with the property. To the northeast, there is a harled outbuilding with openings on the west, south, and east sides, built against a garden wall to the north, featuring a piended platform roof and constructed on the site of an earlier outbuilding. The boundary walls are made of rubble stone and are low, coped, with later steel railings to the west. Large square gatepiers to the west are chamfered, with panels and a corniced cap, and there are later steel gates.
