Section 01

Development description

described as “first floor side extension and first floor rear extension”.

  1. Section 02

    Decision

    The appeal is dismissed.

  2. Section 03

    Main Issue

    The main issue is the effect of the proposal on the living conditions of the occupiers of [address] in respect of outlook.

  3. Section 04

    Reasons

    The proposed extension, whilst having a hipped roof design, would introduce a large expanse of built development within close proximity to windows in the first floor of [address] (No 250). [name] 250 is set at an angle to the proposed extension, given the size and bulk of the proposal and its location with regards to the first floor windows of No 250, it would appear as a dominating structure.

    The appellant argues that the first floor windows of No 250 are not into habitable rooms. However, no formal evidence or floor plans of No 250 has been provided to offer me certainty as to whether the rooms of these first floor rear windows can be considered habitable or not. Paragraph 6d of the appellants statement of case draws my attention to a section of the Council’s Officer Report from the approved development1 of No 250. My interpretation of this extract is that the reference to non-habitable rooms is relating to neighbouring properties and not the proposed extension of No 250 as the appellant appears to interpret it.

    In any event, the first floor rear windows of No 250 are not obscurely glazed and whether the rooms are considered habitable or not, the proximity of the proposed extension to these windows would severely reduce outlook from these rooms. 1 Local Planning Authority Reference: 13524/APP/2017/2198

    I have had regard to the appellants statement of case including figure 3 and comments that the first floor pair of windows to the rear of No 250 serves a single room. Nevertheless, due to the massing and positioning of the proposed extension, it would be an overbearing form of development that would compromise outlook from the pair of first floor windows that would adversely affect the living conditions of occupiers of No 250.

    The area surrounding the appeal site is a fairly densely populated area and it is noted that no objections were raised from neighbouring occupiers. These matters do not alter the harm that I have found that the proposal would have on the occupiers of No 250 with regards to outlook.

    Accordingly, the proposal would have a harmful effect on the living conditions of the occupiers of No 250 with regards to outlook. The proposal would be contrary to Policy BE1 of the Hillingdon Local Plan: [name] – [name] and [name] 11, DMHB 12 and DMHD 1 of the Hillingdon Local Plan: [name] – Development Management Policies which seeks development to protect the amenity of surrounding land and buildings, particularly residential properties, and ensure there is no unacceptable loss of outlook to neighbouring occupiers.

  4. Section 05

    Other Matters

    The proposal would not have an adverse effect on the character and appearance of the surrounding area, nor would it compromise the living conditions of neighbouring occupiers in respect of light. I attribute neutral weight to these matters.

    I also do not consider the approved extensions at No 250 are directly comparable to the proposed scheme particularly with regards to scale, location and orientation of development.

  5. Section 06

    Conclusion

    The proposal would not have a detrimental effect on the living conditions of neighbouring occupiers in respect of light and on the character and appearance of the area. However, these matters would not outweigh the harm I have identified with regards to the effects on the living conditions of occupiers of No 250 with regards to outlook.

    The proposal would conflict with the development plan as a whole and there are no other considerations, including the provisions of the National Planning Policy Framework, which outweigh this finding.

    Therefore, for the reasons given above, the appeal should be dismissed.
