conversion of existing garage into additional living space. Replace external garage door with window to match existing.

  1. Section 02

    Decision

    The appeal is dismissed.

  2. Section 03

    Preliminary Matters

    Outline planning permission was granted by the Council under its Ref: C2014/68760 for the redevelopment the former [name] for a residential led, mixed use development, with a number of subsequent permitted amendments and approval of details. I am advised that permitted development rights under [name] of the General Permitted Development Order 2015 were restricted under Condition 6 of the Reserved Matters Application C2016/73672/ARM.

    The Officer’s report by the Council lists an extensive number of previous planning applications under Site History, as well as a number of enforcement related complaints, but the majority of these relate to the previous use of the site and surrounding area as a trading estate. Most of these are not therefore relevant to the current proposal before me.

  3. Section 04

    Main Issue

    The main issue in this appeal is the effect of the proposed development on the character and appearance of the existing property and on the local area.

  4. Section 05

    Reasons

    The appeal property is an end of terrace residential property on the west side of [address], and forms part of a recent residential led development, comprising predominantly short terraces and small development blocks. There is a very strong uniform character and appearance to the residential development, including the scale and massing of the individual terraces, as well as the treatment of fenestration and materials used. The regularity of the design approach to the terraces is a defining characteristic feature of the immediate context to the appeal property.

    The proposal would replace the existing garage door with a window, associated with the proposed use of the internal space as an additional living space. The proposed window would match the style of the existing windows in the existing property and the terrace.

    As set out above, the character and appearance of the terrace and indeed the wider estate is defined by the very strong uniformity of the design approach. I did not see on my site visit and my attention has not been drawn to any other similar changes to the one proposed under this appeal, which have been permitted or undertaken in the immediate vicinity. Although the proposal, in itself, would be small scale and the fenestration would match the other fenestration used on the front façade, the change from a garage door to a window would be disruptive to the pattern of the development in the terrace and the wider development. It would result in a visually obtrusive amendment that would be seen as a marked and harmful change to the uniform character and appearance of the wider terrace and street scene.

    I therefore conclude that the proposal would unacceptably harm the character and appearance of the local area. This would conflict with Policy 28 of the Sutton Local Plan 2018 and the National Planning Policy Framework, and particularly Section 12, both of which amongst other matters, seek a high quality of design which respects the local context.

  5. Section 06

    Conclusion

    For the reasons given above and having regard to all other matters raised, I conclude that this appeal should be dismissed.
