The story of the Strutt family and that of modern Belper,
which they more or less created, are intertwined. They built the mills and the workers’ housing (to a very high standard for the period) and over several generations endowed the town with numerous benisons, leaving the built environment the better for it; today it is a settlement with, for its size, an extraordinary number of listed buildings. Some, however, failed to survive to be listed, or at least to benefit from the 1968 planning act. This obliged listed buildings to be put through a series of evaluations, resulting in consent or otherwise to demolish or alter them. Prior to 1st January 1969 one had merely to notify the local authority and the Royal Commission on Historic Monuments (so they could record the building) before doing anything drastic.
