In 1840 an area of about 750 acres of land in Cwmafan was leased for 99 years to John Vigurs and subsequently passed to Wright, Butler & Co. Ltd, then to Baldwins Ltd. The terraces of houses built on this land were sublet in 1897 and 1898 for the remainder of the term of this lease, but many were declared unfit for habitation in the 1930s, and demolished.
