Auchenteil, 9 Abercromby Street East, Helensburgh

Auchenteil is a late 19th century, two-storey, four-bay villa located at 9 Abercromby Street East in Helensburgh, featuring classical architectural details. The villa is constructed from squared, stugged, and snecked cream sandstone with ashlar dressings. It has a base course, moulded ashlar mullions and reveals around the windows, an eaves course, and paired brackets supporting the overhanging eaves.

On the principal south elevation, there is a recessed bay to the outer right, which includes an advanced square-plan ashlar porch in the re-entrant angle. This porch has a low balustrade with a column on a pedestal at the southeast angle, and pilasters that support a cornice and a pierced stone parapet adorned with a guilloche pattern. Steps lead up to the doorway on the east side, which features splayed and roll-moulded reveals and a panelled door. Above the doorway, there is a window on the first floor. The main block of the villa is advanced to the left, with a window at the centre, a shallow canted full-height window to the right set back on the first floor, and a slightly advanced bay to the left with a projecting squared full-height window.

Further description includes a central quartrefoil window on the east elevation within a recessed panel that has a stepped surround, flanked by bipartite windows. There are two windows on the first floor. To the right, there is a single-storey wing, and a later conservatory on the west elevation, which has two windows to the left and three windows on the first floor. The villa also features a two-storey wing adjoining to the left.

The windows are predominantly plate glass sash and case, although there are uPVC replacement windows on the first floor. The roof is piended with grey slate and includes a large glass cupola. Corniced ashlar stacks with tall moulded cans are present.

The gatepiers and boundary walls consist of cream sandstone ashlar piers with stop-chamfered angles and pyramidal caps. The flanking quadrant walls have a rubble base with painted red brick above and ashlar coping. There are also tall, coped rubble walls in other areas.
