Braehouse, 15-21 Manse Brae, Rhu

Braehouse is a block of flatted council houses constructed in 1938 for Joseph Weekes, situated on a hillside in Rhu. The building is a two-story, eleven-bay, U-shaped range, designed with stylistic references to 17th-century Scottish architecture. It is painted grey harl with sandstone dressings, a raised cill line, and a base course.

The main, south-east elevation is a long, asymmetrical range with two entrance towers flanking the four central bays. There are three bays to the left of the southwest tower and two bays to the right of the northeast tower. An angled entrance is situated at the outer left corner, corbelled to create an upper element, with a modern door. A widely-spaced bay to the right has an aluminium ground floor door with a narrow arrowslit window above; another ground floor window is located to the right, and a long bipartite window (with replacement glass) sits directly under the eaves. The roofline rises to a gable in the bay to the right of the tower, incorporating a narrow arrowslit in the gable. A ground-floor entrance leads to a rear court and the flats themselves. An advanced, round tower is positioned to the right, with a door on the southwest side connecting to a yard entrance via a flat, semi-circular masonry canopy. Another ground-floor door is on the northeast side of the tower, accompanied by three narrow windows symmetrically arranged under the eaves. A four-bay block is situated to the right of the tower, featuring windows disposed nearly symmetrically in the two bays immediately to its right; the first-floor window to the right is a large tripartite window with timber mullions. A bay to the right rises to a gable, accommodating a ground floor window, two first-floor windows (replacement uPVC hopper windows), and a dormerhead breaking the eaves. Against the tower, a bay has a ground-floor window, a dormerhead above, and a door on the northeast side and another on the southwest side, both united with the yard entrance by a semi-circular masonry canopy. Two bays to the right have windows symmetrically disposed at ground and first floor, with the first-floor window on the outer right being a wide and shallow tripartite with timber mullions.

The northwest (rear) elevation forms a rear court defined by the southwest and northeast jambs, with varying levels and window openings. The southwest elevation consists of four bays with symmetrically disposed windows. The northeast elevation is asymmetrical, featuring an advanced gable on the outer right and windows disposed variously at ground and eaves level; an angled entrance is corbelled to create an upper element.

The windows are generally 12-pane sash and case, with progressively narrower windows towards the northeast; some have been replaced with uPVC windows. The roof is grey slate with triangular tile ridge coping, conical roofs to the towers, and slightly projecting eaves. Squat, broad, coped rendered ridge stacks are present. The interior was not inspected in 1992.

A low, rubble boundary wall, slightly battered and with semi-circular coping, encloses the flats to the east. Small, rendered dividing walls with triangular coping also mark the boundaries.
