(Bath Abbey Cemetery, Histon Road Cemetery, Cambridge, and Southampton Old Cemetery where the design was rejected) but his writing was a major influence on other designers and architects of the period. An unusual creation by Loudon is the memorial to his parents, which stands in the grounds of St John the Baptist, Pinner's parish church. It is in the form of a stone wedge, with a fake stone sarcophagus within. It has been Grade II listed since 1983. Loudon thought that public improvements should be undertaken in a democratic fashion and in a comprehensive and reasonable manner, not sporadically by the benevolence of the wealthy. In 1839, he was commissioned to design the Arboretum at Derby. In his commissions, Loudon displayed the principles that he advocated in his writings; he took into account the general public, aiming to create a space where the classes could mingle easily as well as creating community pride. Plantings were labelled extensively. Loudon's design for the Derby Arboretum paralleled the Loddiges arboretum at Abney Park and served as inspiration for the Royal Botanical Gardens at Kew.
