Officers considered the structures appropriately designed, sufficiently concealed, and unlikely to harm heritage assets, trees or neighbouring living conditions.

“/PP/25/04034:4 iWhether the proposed development would preserve or enhance the character, appearance and significance of the building and wider conservation area; iiWhether the proposal would safeguard the special historic or architectural interest of the designated heritage asset; and iiiWhether the proposal would continue to ensure good living conditions of neighbouring occupiers.”

“Glazing is proposed on the east and south elevation, which faces other flats in the main building at the subject site. The closest neighbouring window is measured at least 14m from the proposed garden room. This is considered sufficiently set back to reduce any unreasonable levels of light spill onto neighbouring flats. The proposal is therefore acceptable in accordance with policies GB10 and CD9 of the Local Plan.”
