Section 01
Development description
a double storey side extension, single storey rear extension and porch extension.
Section 02
Decision
The appeal is dismissed.
Section 03
Background and Main Issue
The Council does not object to the ground floor elements of the proposal and following my site visit I see no reason to disagree. Therefore, the main issue is the effect of the proposed first-floor side extension on the living conditions of the occupiers of [address] (No 1) in respect of their outlook, overshadowing, and privacy.
Section 04
Reasons
The proposed first floor of the side extension would be substantially higher than the existing flat-roofed single-storey projection at the side of the appeal property. At first-floor level the extension would be significantly closer to the small rear garden and the kitchen and bedroom windows of No 1 than the existing main gable wall of the appeal property.
As a result of its mass, height and proximity to the common boundary between these properties, and due to the limited depth of the garden of No 1, the proposal would be an unduly dominant feature that would overshadow the garden and rear rooms of No 1 for much of the day. Further, because of its height and depth next to the common boundary, the first-floor extension would create a harmfully oppressive sense of enclosure and would be an overbearing feature when viewed from the rear garden and from the rear windows of No 1.
In addition, there would be direct views from the study window of the first-floor extension into the top corner of the neighbour’s rear garden and some oblique views over other parts of that garden. The overlooking of the rear garden at close proximity would be an unacceptable invasion of privacy of the occupiers of No 1 when using their back garden.
Therefore, I conclude that the proposed development would be harmful to the living conditions of the occupiers of [address] in respect of their outlook, overshadowing and privacy in conflict with Policy HC4 of the Local Plan for Sefton (April 2017) which seeks to safeguard appropriate levels of residential amenity. The proposal would also conflict with the [address] Extensions Supplementary Planning Document (June 2018) where it seeks to protect the outlook and privacy of residents and prevent unreasonable overshadowing.
Section 05
Conclusion
For the reasons given above, having had regard to the development plan as a whole, I conclude that the appeal should be dismissed.
