Why it was refused
- The proposed development by reason of the width, height and siting of the first floor side extension together with the uncharacteristic proposed external material finish, would appear prominent and incongruous within the street scene, contrasting with the established spacing and material finish of the surrounding area, and therefore harming the verdant character of the surrounding area. This harm is exacerbated by reason of the prominent siting of the dwelling, the surrounding woodland context and the stark appearance of the external material finish. It would therefore be contrary to policy DM9 of the Surrey Heath Core Strategy and Development Management Policies 2012, DH1 of the Emerging Local Plan 2019-2038, the Residential Design Guide Supplementary Planning Document 2017 and policy WNP2.1 of the Windlesham Neighbourhood Plan 2017.
- In the absence of the submission of a detailed Arboricultural Impact Assessment and Arboricultural Method Statement, it has not been adequately demonstrated that the proposed development would not have an adverse impact on the long term health and retention of on-site mature and/or protected trees. These trees make a significant and positive contribution to the character and visual amenity of the area, and their reduction or loss would be harmful to the verdant character and amenity of the area. As such, it has not been adequately demonstrated that the proposal complies with the National Planning Policy Framework, policy DM9 of the Surrey Heath Core Strategy and Development Management Policies 2012 and policy DH1 of the emerging Local Plan 2019-2038.
