The proposed full width extension at lower ground floor level, by reason of its detailed design, materials and positioning would disrupt the rhythm of rear additions within the terrace that would have a detrimental impact on the character and appearance of the building, the terrace of which it forms part and the surrounding Oxford Gardens Conservation Area. As such the proposal is contrary to the 'saved' policies of the Unitary Development Plan 2002 (as amended September 2007), in particular Policy CD47 Extensions, CD48 Conservatories and CD63 (Views). The proposal is also considered contrary to the adopted Core Strategy, in particular Policies CL1, CL2, CL3 and CL6.

The applicant has failed to demonstrate, in particular by reason of a lack of information relating to existing and proposed boundary wall height to the adjoining property at No 113 Chesterton Road, that the proposed lower ground floor extension would not have a detrimental impact on the amenity of neighbouring properties, contrary to policies of the development plan, in particular Core Strategy policy CL5 and saved UDP policies CD47 and CD48.
