Description

Tanybryn is a pair of two-storey cottages designed for quarry workers, built in a rectangular plan and aligned roughly north-south, with the northern cottage being slightly larger than the southern one. The cottages are constructed from roughly coursed rubblestone and topped with a slate roof. Each cottage features recessed four-paned sash windows with slate cills on both floors, and they are flanked by recessed boarded doors that are sheltered by shallow flat-roofed porches made of slate slabwork, which have a simple moulded entablature. There are four chimneys in total, with two integrated into the gable ends and two located on the ridge. The interior was not inspected during the survey.

Local climate

Tanybryn sits in one of the wettest parts of the UK, with an average of 1,360 mm of rain a year. This makes it wetter than 96% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 95% of listed buildings.

It experiences an average of 40 freeze-thaw cycles a year, more than 78% of listed buildings. Of these, 22 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.
