The development would be below the threshold for BNG, and therefore, would be exempt.”

“Issues and balancing 6.6The proposed replacement windows and doors, given their design, scale and materials would have acceptable impact on the neighbouring properties and would preserve the character, appearance and significance of the building and wider conservation area. Overall, the proposal would comply with the relevant policies in the development plan, as well as complying with the statutory requirements for development within a conservation area.”
