Appeal 3354680

The appeal is dismissed.

The appeal form indicates that it was agreed to change the description of the proposed development. I have therefore used the amended description within the banner heading.

Appeal APP/L5240/D/24/3354678 is for a similar extension at [address] (No 9). The appellant indicates that the developments proposed in both this appeal and at No 9 would be carried out simultaneously. Nonetheless, I have not been presented with a completed planning obligation to ensure both appeal developments would be carried out as a single scheme. As such, I have determined the appeal on this basis.

The main issues are the effect of the proposal on the: • Character and appearance of the area; and • Living conditions of the occupiers of No 9 with particular regard to outlook.

The appeal property is typical of the dwellings along the northern section of this part of [address] which comprise well-proportioned pairs of two-storey semi-detached dwellings generously set back from the highway. These pairs are predominantly similar in their form and design, giving the street scene a pleasing rhythm. Their hipped roofs and appreciable gap between the side elevations above ground floor level creates an openness between the majority of the pairs of dwellings, giving the street scene a spacious character.

The appeal property appears relatively unaltered above ground floor level with hipped roof and sizable gap between the first-floor side elevation and that of No 9, contributing to the characteristic spaciousness of the street scene. The adjoining dwelling has been extended to the side, unbalancing the symmetry of the pair. Nevertheless, the generous setback of the first-floor of the extension and use of a hipped roof allow it to remain subservient to the host dwelling and reflective of the character of the host property and the locality.

The proposed side extension would intrude on the existing gap between the appeal dwelling and No 9, with the use of a barn hipped roof further increasing its visual bulk. As such, the proposed side extension would erode the existing spacious relationship with No 9, harming its contribution to the openness of the street scene. Further, the use of a barn hipped roof would appear out of character with the hipped roofs of the majority of the surrounding dwellings that form a strong feature of the area.

The degree of setback of the front elevations from first-floor extensions varies within the area. The ridge line of the proposal would be stepped down slightly below that of the host dwelling with the first-floor front elevation set back minimally. When this minor setback is combined with the additional visual bulk of the barn hipped roof, the proposal would appear dominant, disrupting the proportions of the host dwelling. This bulk is exacerbated to the rear elevation by the proposed two-storey projection.

The appellant cites examples of barn hipped roofs, narrow gaps between dwellings, and dwellings that vary in style. Nonetheless, these are some distance from the appeal site. These do not therefore form the predominant character of the area surrounding the appeal site which I have identified above, and in which the appeal proposal would be viewed.

For these reasons, therefore, the development would be harmful to the character and appearance of the area. Consequently, in this regard, it would conflict with the relevant provisions of Policies SP4, DM10.1 and DM10.7 of the Croydon Local Plan (2018) (Local Plan). When read together these policies require development to respect local character including in its layout and massing, its roof form to be sympathetic with its local context, and for extensions to be subservient.

The appeal site and No 9 have a similar rear building line at first-floor level and are generously spaced. As such the existing relationship between the dwellings affords the occupiers of No 9 an open outlook from the rear windows and garden area.

The proposed extension would extend close to the shared boundary with No 9. The proposal would project at two-storey level notably beyond the existing first-floor rear elevation of No 9 with a large and prominent blank wall facing this boundary. The close relationship to the boundary combined with the scale of the rear projection would cause the proposal to appear dominant and overbearing when viewed from the rear garden area and rear windows of No 9, unacceptably harming the outlook of its occupiers.

For these reasons, therefore, the development would be harmful to the outlook of the occupiers of No 9. Consequently, in this regard, it would conflict with the relevant provisions of Policies SP4 and DM10.6. When read together, these policies require new development to enhance well-being and protect the living conditions of adjoining occupiers.

No objections from interested parties were received with one in support, and the proposal is not located within a conservation area. Nonetheless, these do not justify the above identified harm to the character and appearance of the area and neighbouring occupiers.

The appellant has raised concerns regarding the time it took the Council to validate and determine the original application. However, this is a procedural matter and not something I can consider as part of this appeal.

For the reasons given above the appeal should be dismissed.
