The Kersley Road and Church Street corner
This house had three storeys originally but a fourth storey has been added behind a slate Mansard Roof. These roofs are built of timber and slate and are light in weight. A brick extension would have been heavy, perhaps causing problems with the foundations, expensive, and would have taken much longer to build. Today the slates are backed with heat insulation of some sort. When Mansard invented the design for King Louis the Fourteenth, the wind whistled through the slates. As only the servant lived up there, it did not matter to Louis.
