Section 01

Development description

rear extension on to an existing 3m extension, making the total length 5m out.

  1. Section 02

    Decision

    The appeal is allowed and prior approval is granted under the provisions of Article 3(1) and Schedule 2, Part 1, Class A, paragraph A.4 of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended) for rear extension on to an existing 3m extension, making the total length 5m out at [site address] in accordance with the application P/3155/21/PRIOR, dated 27 July 2021, and the details submitted with it including plan no 104 and site plan, pursuant to Article 3(1) and Schedule 2, Part 1, Class A, paragraph A.4(2) and subject to the following

  2. Section 03

    condition:

    Notwithstanding the provisions of the Town and Country Planning (General Permitted Development) (England) Order 2015 (or any order revoking and re-enacting that order with or without modification), no windows or doors shall be installed in the side elevations of the development hereby permitted.

  3. Section 04

    Preliminary Matters

    Under Article 3(1) and Schedule 2, Part 1, Class A of the Town and Country Planning (General Permitted Development) (England) Order 2015 as amended (the GPDO), planning permission is granted for the enlargement of a dwellinghouse subject to limitations and conditions.

    Where an application is made for a determination as to whether prior approval is required for development which exceeds the limits in paragraph A.1(f) but is allowed by paragraph A.1(g) to Part 1, paragraph A.4(7) to Part 1 requires the local planning authority to assess the impact of the proposed development on the amenity of any adjoining premises, where any owner or occupier of any adjoining premises objects to the proposed development.

  4. Section 05

    Main Issue

    The main issue in this appeal is the impact of the proposed development on the amenity of adjoining premises with particular regard to light and outlook at [address].

  5. Section 06

    Reasons

    There is an existing 3m long single storey extension along the boundary between no. 15 and 17. The proposed development would increase this to a 5m single storey extension. There is a main window to a living room to the ground floor rear elevation of [address].

    Taking into account the proposed height of the extension along with the existing relationship between the rear ground floor windows at no. 17 and the built form at no. 15, the proposed development would be unlikely to result in an inappropriately harmful loss of light to the occupiers of [address].

    The main outlook from the rear ground floor windows at no. 17 is across the rear garden. Although the proposed extension would be visible in peripheral views, and given the existing extension in a similar location, the main outlook would not significantly alter.

    Considering the temporary nature and limited scale of any noise and disturbance during building work, this would not result in unacceptable harm to the living conditions of nearby occupiers.

    I have taken into account Policy DM1 of the Harrow Council Development Management Policies July 2013 insofar as it relates to this matter. This sets out that all proposals detrimental to the privacy and amenity of neighbouring occupiers will be resisted. For the reasons set out above, I find that the proposed development complies with this policy. Albeit that the principle of development is established through the grant of permission by the GPDO.

    Consequently, the proposed development would have an acceptable impact on the amenity of adjoining premises, with particular regard to light and outlook at [address].

  6. Section 07

    Conditions

    The development is required to comply with the conditions, limitations and restrictions set out in the Order. In addition, the extension would be adjacent to neighbouring gardens and replace existing boundary treatment. Therefore, windows in the flank walls would be harmful to the privacy of the neighbouring occupiers. Consequently, a condition is required to ensure windows would not be inserted in these side elevations in the future, in the interests of the living conditions of neighbouring occupiers.

  7. Section 08

    Conclusion

    For the reasons given above, I conclude that the appeal should be allowed and prior approval should be granted.
