Why it was refused

  1. The replacement door to the front elevation, by reason of its design, appearance and materials used results in a development which is out of keeping with the character and appearance of the dwelling and streetscene of Dickinson Square, which fails to preserve or enhance the character and appearance of the Conservation Area. The development leads to less than substantial harm to the Dickinson Square Conservation Area, however no public benefits have been demonstrated which would outweigh the harm. The development is contrary to Policies CP1 and CP12 of the Core Strategy (adopted October 2011), Policies DM1, DM3 and Appendix 2 of the Development Management Policies LDD (adopted July 2013), The Dickinson Square Conservation Area Appraisal (2014) and NPPF (2024).

From the council's decision notice.
