Why it was refused

The proposed development by virtue of the materiality of the replacement windows and design approach of the single storey rear extensions would result in less than substantial harm to the significance of the Grade II listed West Lodge. The public benefits do not outweigh this harm. This would be contrary to policy D3 of the Local Plan: Strategy and Sites 2015 - 2034, policies D18 and D19 of the Local Plan: Development Management Policies 2023, the National Planning Policy Framework (NPPF) and the requirements of Section 16(2) of the Planning (Listed Building and Conservation Areas) Act 1990.

From the council's decision notice.
