This polygon is dominated by terraced housing although other housing types exist within it. The terraces date to the early 20th century, first appearing on the 1905 OS map. Prior to this, a small number of detached houses had been developed in the area. The houses were built on the site of Garrow Tree Hill Colliery and Swallow Wood Pit. These are marked on the 1st Edition OS map of 1854 but Garrow Tree Hill Colliery is known to have been operating from at least 1758 (Munford 2003, 27). Coal and ironstone were mined from the pits for the Walker Brothers nearby ironworks. The Kimberworth pre-enclosure plan of 1796 marks the area as containing coal and locates it in the area of the former open fields. Legibility is fragmentary as the mining heritage is recalled in the street names 'Pitt Street' and 'North Pitt Street'.
