Mixed development developed piecemeal on the older settlement at Blacker. The earlier phase of development was mostly in place by 1855 maps with some expansion by 1893. These properties may have included nail making workshops which were common in the Mapplewell area from the 18th century (see Taylor 1994 for overview of nail making in the area). This area had been enclosed by 1775 (Jefferys 1775) but the large areas of common in the surrounding area suggest that this was enclosed from common. There is no legibility of these landscapes or the earlier housing.
