Why it was refused

  1. The proposed increase in the depth of the rear infill extension, combined with the removal of the historic canted bay, would cause harm to the heritage significance of the property and the wider conservation area. The cumulative alterations would appear incongruous, unsympathetic, and over dominant in relation to the original building form. The applicant's justification is based on private internal functional improvements, which do not constitute public benefits capable of outweighing the identified less than substantial harm. In accordance with paragraphs 202-204 of the National Planning Policy Framework (NPPF), great weight must be given to the conservation of heritage assets, and any harm should be clearly justified and outweighed by public benefits. This has not been achieved in this instance. The proposal is therefore contrary to Policies Q5, Q11, and Q22 of the Lambeth Local Plan (2021) and the relevant provisions of the NPPF.
