Why it was refused

  1. The Local Planning Authority considers that the proposal, due to the positioning of the proposed rear extension in close proximity to the protected tree T2, would likely lead to significant harm to this protected tree, if not its likely future loss, to the detriment of its positive wider functions and the character and appearance of the Boston Spa Conservation Area (less than substantial harm that is not outweighed by public benefit). This is considered to be harmful to amenity and character, and wider climate change and air pollution objectives. The proposal is thus considered to be contrary to the wider aims and objectives of policies SP13, P10, P11, P12 of the Core Strategy, saved policies GP5, N19, N20 and LD1 of the Unitary Development Plan, policy LAND2 of the Natural Resources and Waste DPD, policy HDG1 of the Householder Design Guide SPD and guidance within the Council's Guideline Distances to Trees from Development Document, Merrion House 110 Merrion Centre Leeds LS2 8BB Town and Country Planning Act 1990 BS5837 Trees in Relation to Design, Demolition and Construction document, and the NPPF.

From the council's decision notice.
