This polygon is that part of the 'Flower Estate' that won a Gold Medal for its design at the Yorkshire and North Midland Cottage Exhibition in 1907 (Harman and Minnis 2004). The earliest houses in the polygon are those on a grid iron pattern along Wincobank Avenue and Heather Road. These were built for Sheffield Corporation in 1903-4. The most distinctive part of the estate is its layout, which was conceived to produce gently curving streets round a central axis (Primrose Avenue) that focused the observer's line of sight towards a church on the triangle of land between Acacia Road and Primrose Avenue. This church was never built and instead the avenue now visually terminates on Hinde House Junior School. There are a variety of house designs around the estate, some of which were developed as basic types by the Corporation on the later estates such as Manor and Parsons Cross. The layout of this area on the 1851 OS shows large surveyed divisions indicating that enclosure here may have involved a high degree of planning. The nearby place name 'West Field' indicates possible open field agriculture in the late medieval period. This part of the Flower Estate is important in terms of architectural and social history. Little legibility of the previous surveyed enclosure.
