Description

Bronwydd is a two-storey house built from battered rock-faced red stone, with the upper floor rendered and whitewashed. It features slate roofs with axial and lateral stacks. The house is single room wide and has nine bedrooms, with the main reception rooms located at the southwest end and a narrower service wing aligned at the northeast. The lower gables create slight wings at each end of the main range, though they are asymmetrical.

The entrance has a panelled door with a suspended canopy, and there is a part-external stack for the dining room to the right. The windows are timber, paned, and placed irregularly, with those on the upper floor positioned close to the eaves. To the left of the entrance, there is a double transomed window leading to the stair. The dining room features a canted bay on the rear (southeast) side, with the roof extended to create a sheltered porch over French doors. Some windows are small-paned casements, with some including transoms. A two-storey square bay window with leaded glazing projects from the end elevation, providing light to the drawing room.

Inside, the entrance hall leads to a lateral dog-leg stair, with a smoking room located opposite. The dining room includes a tiled chimneypiece, and various joinery details such as chair rails and dados are preserved, along with patterned leadwork in the windows.

Bronwydd sits in one of the wettest parts of the UK, with an average of 1,210 mm of rain a year. This makes it wetter than 92% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 93% of listed buildings.

It experiences an average of 23 freeze-thaw cycles a year, fewer than 75% of listed buildings. Of these, 11 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.

Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
