Currently in multiple light industrial and commercial occupancy as a industrial estate, the majority of these buildings once formed part of the massive Newton Chambers & Co's Thorncliffe Works. This company (founded in 1793) dominated Chapeltown and High Green for nearly 200 years before being sold off in the 1970s. The buildings within this polygon are first depicted on the 1905 25 inch OS sheet as 'Thorncliffe Iron Works'.
