Hazelwood Cottage, Hazelwood House, Torwoodhill Road, Rhu

Hazelwood House, built probably in the 1830s, was extensively remodelled in the late 19th century in an Arts and Crafts style. It is a two-story, asymmetrical, gabled villa with a rectangular plan and four bays. The exterior is white-painted harl with red sandstone margins and dressings, incorporating mock half-timbering and red tile-hanging. Ashlar quoin strips are also present.

The main elevation features a four-bay main block and a lower conservatory wing to the outer left. The central two bays stand over a raised basement. A gabled, timber porch is reached by a stone stair in the penultimate bay to the right, with a square dormer above. The outer right bay has a timber transomed and mullioned window at ground level, with a gabled dormerhead above. A full-height, canted, gabled window is located to the left of the porch, featuring a timber rusticated, loggia-type basement, cast-iron railings and a transomed, mullioned timber ground floor window. The first floor is tile-hung, with a bipartite window above. A broad, advanced bay to the outer left has a canted, quadripartite ground floor window, a deep base course, curved sides, and a jettied, tile-hung first floor with a canted window on timber consoles; half-timbering adorns the gablehead. A lower bay to the outer left is harled with a red sandstone base and a timber conservatory.

The side elevation showcases three asymmetrical bays. A broad gable to the outer left is accompanied by a lower, advanced, canted, and gabled bay to the right of the gable, featuring a window at ground level and a swept, tile-hung first floor. The lower two bays to the right have symmetrically disposed windows at ground level, with a bipartite dormerhead at the centre.

Plate glass casement windows, along with sash and case windows, are found throughout the property. The roof is grey slate with bargeboards, and rendered and coped ridge stacks. The interior was not inspected in 1993.

To the east of the house is a single-story, long, rectangular-plan motor house and stable. It is constructed with white-painted harl, red sandstone dressings and margins, and tile-hung details, featuring strip quoins and chamfered reveals. The northwest elevation (main elevation) has a gable to the outer right, a bipartite window at ground level, a tile-hung gablehead, and a bipartite attic window. A broad, two-leaf boarded garage door with a multi-paned upper glazed panel is centrally located, with a single door and a bipartite window to the outer left. The north (street) elevation has three bays, with a curved outer right bay featuring a red sandstone battlemented parapet and a segmental, eyelet window; a similar window is found in the outer left bay. A hay loft breaks the eaves at the centre, with a red sandstone cill. The motor house has multi-paned casement windows, a grey slate roof with triangulated terracotta ridge tiles, cast-iron finials, projecting eaves, and exposed rafters.

A cottage, located to the northeast of the house, is a later replacement for a former white-painted harl and half-timbered cottage, occupying a similar footprint.

The gates and gatepiers consist of rubble and harl circular drum piers with ashlar, pyramidal caps. Geometric cast-iron gates complete the ensemble.
