By reason of its size, location and detailed design, the proposed extension would detract from the appearance of the building and its neighbours to the detriment of the character and appearance of the Oxford Gardens St. Quintin Conservation Area of which these premises form a part. Therefore, the development is considered to conflict with Council policy as stated in the Unitary Development Plan, notably Chapter 4 and Policies CD25, CD41, CD52 and CD53 and the Oxford Gardens St. Quintin Conservation Area Proposals Statement.
