Torwood House, Torwoodhill Road, Rhu

Torwood House is an earlier 19th-century cottage that was extended in 1836 with further additions in 1845. It is a two-storey, asymmetrical, rectangular-plan, gabled villa with six bays. The exterior is white-painted harl with sandstone dressings and margins. The building features a base course, quoin strips, hoodmoulds, projecting eaves, and exposed rafters.

The south elevation has five asymmetrical bays. A broad, battlemented tower bay is on the outer left, with paired squat finials at the corners. It contains a quadripartite window at ground level, a single window at the first floor, and a lintel that interrupts the string course line of the jettied parapet. To the right, a lower two-bay entrance block is slightly advanced. A gabled sandstone porch provides access via a pair of wooden doors. A quadripartite window connects the porch and tower on the ground floor, with a lean-to slated roof, and there are symmetrically disposed gabled dormerheads on the first floor. A broad, gabled bay is slightly advanced to the right of the centre, featuring a projecting tripartite window at ground level and a bipartite window at the first floor, with a hoodmould. A lower, narrower gabled bay is on the outer right with a tripartite window at ground level, hoodmould, and a single window in the gablehead.

The west elevation features a two-bay main block with a battlemented design and a single-storey wing on the outer left. A full-height, sandstone canted window is on the outer right, with a sandstone decorative plaque above at the centre of the parapet. A canted oriel, corbelled and with a lead roof, is on the outer left. A narrow door is asymmetrically placed on the outer left, and a blank wall forms the single-storey block on the outer left.

The north (rear) elevation has five bays. There is an asymmetrical M-gable on the outer left; a broad two-bay gable is recessed to the right, abutting the tower. Single-storey outbuildings are at the ground level on the outer right.

The east elevation has three bays, with a broad bay on the outer left. Windows are symmetrically disposed to the left bay, with others situated on the first floor of the two bays to the right. A broad, boarded garage door is on the outer right, and a narrow door with a plate glass letterbox fanlight is immediately to the left. A narrow window and a broader window are to the left, and a broad window has been blocked with a modern timber window.

Windows are of four, eight, and six panes, with a four-pane over plate glass sash and case style for the bay to the left of the door. The roof is covered in grey slate, and there are tall, sandstone, corniced stacks topped with octagonal cans.
