Appeal Decision
Site visit made on 6 January 2025
by Nicola Davies BA DipTP MRTPI
an Inspector appointed by the Secretary of State
Decision date: 20 January 2025
Appeal Ref: APP/D1590/D/24/3350728
6 The Gables, Leigh-on-Sea, Essex SS9 4DU
• The appeal is made under section 78 of the Town and Country Planning Act 1990 (as amended)
against a refusal to grant planning permission.
• The appeal is made by Mr Ryan Hamilton against the decision of Southend on Sea Borough Council.
• The application Ref is 24/00629/FULH.
• The development proposed is a single storey rear extension.
Decision
1. The appeal is allowed and planning permission is granted for a single storey rear
extension at 6 The Gables, Leigh-on-Sea, Essex SS9 4DU in accordance with the
terms of the application, Ref 24/00629/FULH, subject to the following conditions: -
1) The development hereby permitted shall begin no later than 3 years from the
date of this decision.
2) The development hereby permitted shall be carried out in accordance with
the following approved plans: 4065-12-1 Rev B, 4064-12-2 Revision B and
4065-12-3 Revision C.
3) The materials to be used in the construction of the external surfaces of the
development hereby permitted shall match those used in the existing
building.
4) The roof of the development hereby approved shall not be used as a
balcony, roof garden or terrace or for any other purpose at any time.
Application for costs
2. An application for costs was made by Mr Ryan Hamilton against Southend on Sea
Borough Council and that will be the subject of a separate decision.
Preliminary Matters
3. The planning application form indicates that the development has been started but
has not yet been completed. The officer’s report indicates that the proposal has
been sought retrospectively. The Council officer’s report also advises the height of
the extension to be 3.5m. This has been informed by the annotation on the plans
that support the planning application. Indeed, the annotations of the proposals plan
shows the height of the parapet side walls to be 3.56m.
4. Subsequent to this the height of the rear extension has been re-measured and
advised to be 3.16m in height. A supplementary report circulated ahead of the
Appeal Decision APP/D1590/D/24/3350728
2
Planning Committee meeting advised members of this amended measurement.
Notwithstanding this, the application details have not been revised. The plans as
submitted are what was before members of the planning committee for
consideration, and which are now the subject of this appeal.
5. In the interests of clarity, I have considered the proposal as a stand-alone
development, on the basis of the information illustrated on the planning application
plans as submitted to and determined by the Council and not what I saw on site.
6. A revised version of the National Planning Policy Framework (the Framework) has
been published since the planning application was determined by the Council. I
have had regard to the revised Framework in reaching my decision.
Main Issue
7. The main issue raised by this appeal is the effect of the proposed development on
the living conditions of the occupiers of the adjoining property, 5 The Gables, in
respect of daylight and sunlight.
Reasons
8. The rear extension would run along the common boundary with No.5 with the
extension sited in close proximity to the side wall of that property. At ground level
No.5 hosts a partly obscure glazed door in the flank elevation that is understood to
serve a kitchen. This is not the sole source of light for this room as there is a
window in the rear elevation of the property that provides light and outlook for the
kitchen. Taking into account the orientation of the sun, the proposal would not cast
substantial overshadowing of the flank elevation for a significant portion of the day.
Whilst the extension would be sited close to the kitchen door, I do not find that the
occupiers of No.5 would experience harmful loss of daylight and/or sunlight as a
result of the rear extension.
9. For these reasons, I conclude that the proposed development would not harm the
living conditions of the occupiers of the adjoining property, 5 The Gables, in respect
of daylight and sunlight. As such, the proposed development would not conflict
with Policies KP2 and CP4 of the Southend-on-Sea Core Strategy 2007, Policies
DM1 and DM3 of the Southend-on-Sea Development Management Document
2015, the Southend-on-Sea Design and Townscape Guide 2009, the National
Design Guide 2021 and the provisions of the Framework. These policies and the
Framework seek, amongst other matters, to ensure that development protects the
amenities of immediate neighbours.
Conditions
10. I have considered the planning conditions put forward by the Council in light of
paragraph 56 of the Framework and the Planning Practice Guidance. In addition to
the standard time limit condition and in the interests of certainty it is appropriate
that there is a condition requiring the development be carried out in accordance
with the approved plans. In the visual interests of the locality matching materials of
the extension is necessary. In the interests of neighbouring living conditions, a
condition is necessary to prevent the roof of the extension being used as a balcony,
roof garden or terrace.

Conclusion
11. For the reasons set out above, and subject to the conditions listed, this appeal
should be allowed.

Costs Decision
Site visit made on 6 January 2025
by Nicola Davies BA DipTP MRTPI
an Inspector appointed by the Secretary of State
Decision date: 20 January 2025
Costs application in relation to Appeal Ref: APP/D1590/D/24/3350728
6 The Gables, Leigh-on-Sea, Essex SS9 4DU
• The application is made under the Town and Country Planning Act 1990 (as amended), sections 78,
322 and Schedule 6, and the Local Government Act 1972, section 250(5).
• The application is made by Mr Ryan Hamilton for a full award of costs against Southend on Sea
Borough Council.
• The appeal was against the refusal of planning permission for a single storey rear extension .
Decision
1. The application for an award of costs is refused.
Reasons
2. The Planning Practice Guidance advises that costs may be awarded against a
party who has behaved unreasonably and thereby caused the party applying for
costs to incur unnecessary or wasted expense in the appeal process.
3. On two occasions ahead of the committee meeting the appellant advised the
planning officer that the height of the extension is 3.16m and not 3.5m (3.56m as
annotated on the plans) as set out on the submitted plans. A note to this effect was
included in the supplementary report circulated ahead of the committee meeting
held on 26 June 2024. Notwithstanding this, it is alleged that the Council members
referred to the incorrect height during the course of discussion and votes by
members. Without this influence it is suggested that members would likely to have
been more inclined to grant planning permission noting the fact that there would be
no substantial difference in the proposal plans and that other plans submitted that
were confirmed did not require prior approval (a fallback position).
4. It is also considered that a particular ward Councillor should not have been
participating in and influencing the discussion and voting at the committee meeting
as he had spoken with the residents of No.5 The Gables and visited the property to
make an assessment. It is contested that this would have affected his impartiality.
Without this procedural unreasonableness the appeal may have been avoided.
5. Members did not give due weight to the fact there was a previous rear conservatory
addition and trees along the common boundary that would have blocked sunlight
and limited daylight to the side kitchen door at No.5 The Gables. Furthermore, the
prior approval fallback was not considered. The obscure glazing within the door is
a secondary source of light into a non-habitable room. The Council’s Design and
Townscape Guide Supplementary Planning Document (SPD) supports the
Costs Decision APP/D1590/D/24/3350728

application position with respect to potential loss of light caused by extension. The
appeal could have been avoided had these factors been considered.
6. Further to the above, a previous planning submission had been made to regularise
the ground floor extension and erect a first storey extension. The proposal was
refused on the basis of the combined impact of the extensions on the character and
appearance of the site. It was not refused on the basis of harm to the living
conditions of No.5 The Gables. Given that proposal was to regularise the single
storey rear extension, it is not considered that members approached this appealed
proposal in a consistent manner.
7. For these reason the applicant considers that the Council has acted unreasonably
procedurally and substantively. As such, the applicant has incurred the
unnecessary time and associated cost of the appeal process as the applicant has
had to obtain professional assistance and submit an appeal.
8. The Council contends that the applicant did not provide further specific evidence,
such as photographic evidence showing measurements on site, to support the
revised height measurement. Furthermore, the applicant did not seek to amend the
submitted plans or withdraw the application from the committee agenda. The
planning application was therefore assessed on the basis of the submitted plans
that annotated the height of the single storey rear extension to be 3.56m. Members
had the benefit of this information within the officer report to committee, which also
contained photographs of the extension as built and photographs demonstrating
the relationship with neighbouring dwellings.
9. With regard to the conduct of a ward Councillor, that member declared a non-
pecuniary interest at the start of the meeting. The Council’s legal team were
satisfied that the declaration of interest was appropriate and the meeting could
proceed. The Council consider it carried out its responsibilities in assessing the
application giving due weight to material considerations finding the development to
be not policy compliant.
10. Plans showing the development and the site prior to the unauthorised extension
being erected and photographs of the site were made available to members in the
agenda and committee presentation. Members were aware of the circumstances
on site prior to the erection of the extension and were able to take these into
account in the decision-making process.
11. The Council contends that the committee report outlined the key issue and
identified areas where judgement could be applied. Therefore, the Council is of the
opinion that members, in applying their judgement, could come to a different
conclusion on the individual merits of those considerations to that of its officers.
12. I am satisfied that members of the Council’s Planning Committee had sufficient
information before them to allow them to make a reasoned assessment of the
proposal and its merits. It is open for the Councillors to make their own judgement
on the evidence that is before them and come to a different conclusion to that of an
officer. This is not a failure to exercise the development management functions
properly. If there is concern, the Council has advised that the conduct of an elected
member can be reported to the monitoring officer and this is a process separate to
planning.
Costs Decision APP/D1590/D/24/3350728

13. With regard to the potential false claims made by a ward Councillor who is said to
have visited the site and measured the extension, the plans and officer report that
were before members annotated the extension’s height. The plans that
accompanied the planning application were available to members and this is what
was before members for consideration. Irrespective of the corrected measurement
provided within the supplementary report circulated ahead of the committee
meeting and whether the Councillors measurement was correct or not, the details
pertaining to the proposal submission were not amended.
14. On the evidence before me there is no clear indication that members ignored or did
not have regard to the guidance contained within the Design and Townscape Guide
SPD regarding loss of light caused by extensions. Similarly, I do not find that any
assessment made in respect of the previous applications were clearly ignored or
disregarded.
15. With regard to pre-existing circumstances the existing trees could be removed
without requiring any permission or approval. The pre-existing circumstances were
set out in the officer report. It may be that members may have come to a different
view on the proposal had the planning application been amended to reflect the re-
measured height of the proposed rear extension, if that was indeed the proposal
that was actually being sought planning permission. However, the plans were not
revised and the height as set out within the supplementary report was not before
members for consideration. The fact that I have come to a different view to the
proposal to that of the committee members does not, of itself, show that the Council
has behaved unreasonably.
Conclusion
16. I therefore find that unreasonable behaviour resulting in unnecessary or wasted
expense, as described in the Planning Practice Guidance, has not been
demonstrated.
