Description

Bronheulog is a large, two-storey gentry house dating back to the 18th century, with a central nine-bay section flanked by advanced two-bay wings. The house is constructed of rubble stone on a battered base and has slate roofs, with hipped sides and tiled ridges featuring terracotta finials on the flanking wings. Four large gabled chimneys add to the appearance, with two at the rear and one projecting from each wing. Modern skylights have been added to the front and rear of the roofs.

The main entrance is through a modern single-storey, slated porch, leading to a part-glazed door. The central section features 18th-century unhorned, recessed 12-pane sash windows, characterised by thick glazing bars and simple window frames. The left wing has larger, slightly recessed 12-pane sashes of the later 18th or early 19th century. The first-floor windows of the right wing are similar, though the ground-floor windows there have been replaced with uPVC.

The rear and sides are rendered and have irregular openings. The rear elevation includes four first-floor 12-pane sashes, alongside a modern door with a canopy porch on the right, with a 20th-century 8-pane staircase window positioned above and to the right of the door. A lower, two-storey 19th-century service wing extends at a right angle to the left, featuring a lean-to slated projection and a continuous canopy porch over the entrance on the right. A wide, single-storey canted bay with a flat roof, dating from the early 20th century, is located to the right of this entrance, with eight-pane sashes. The service wing includes an entrance on its eastern side, with 12-pane sashes on each floor to the right and a 6-pane 19th-century sash on the first floor and a 20th-century window below on the west face.

Adjacent to the right wing is a low, single-storey extension from the later 19th century, constructed in a similar style. It incorporates a late 19th-century 12-pane sliding sash and a contemporary 12-pane casement in the upper gable, with modern replacements elsewhere.

Inside, a fine early 18th-century dog-leg staircase rises beneath an arch with a moulded wooden architrave and projecting key. Flanking this are two two-panel doors with simple architraves. The staircase features turned balusters, flat-capped square newels, panelled sides, and a plain rail, rising to an attic, formerly a dormer floor, terminating in a short gallery with flat-shaped balusters. A similar arch at the first-floor landing provides access to the upper flight via a later boarded door. Ground-floor windows incorporate panelled reveals with raised and fielded panels.
