Description
Sunnyside is a detached house built between 1846 and 1847 for the Chartist Co-operative Land Company. It is constructed of stuccoed brick and features a Welsh slate roof. The house has one storey and consists of three bays, with a slightly projecting pedimented center that includes a bay window addition and a rectangular panel on the bargeboards. The outer bays have sash windows set in reveals, and there is a plinth at the base. The return gables are adorned with rectangular panels that extend downwards, a design characteristic used throughout O'Connorville. The right end has a sash window, while a lean-to and a long low wing have been added to the left side. There are three stacks at the rear, now incorporated into a catslide roofed rear outshut addition. The interior has not been inspected. Sunnyside is considered one of the best surviving examples of houses in O'Connorville, which was founded by Feargus O'Connor, a leader of the Chartist movement. This settlement was the first established under his Land Plan and represents an important development following Chartism, as well as a precursor to Garden Cities. The settlement originally included a school and 35 cottages, each with two to four acres of land.
Local climate
Sunnyside sits in one of the driest parts of the UK, with an average of 700 mm of rain a year. This makes it drier than 91% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 88% of listed buildings.
It experiences an average of 28 freeze-thaw cycles a year, fewer than 69% of listed buildings. Of these, 13 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.
