Inspector’s Reasoning
Appeal Decision
Site visit made on 16 December 2025
by MG Garrard LLB (Hons), PGDip.LP, Solicitor
an Inspector appointed by the Secretary of State
Decision date: 22 January 2026
Appeal Ref: 6001624
3 Moorhill Road, Whitnash, Warwickshire CV31 2LG
• 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 Daljit Singh against the decision of Warwick District Council.
• The application Ref is W/25/0494 was refused by notice dated 10 October 2025.
• The development proposed is single storey rear extension.
Decision
1. The appeal is dismissed.
Main Issues
2. The main issues are the effect of the proposed development on:
• the living conditions of the occupiers of 5 Moorhill Road with regard to light
and outlook; and
• protected species.
Reasons
Living conditions
3. Paired with 5 Moorhill Road, the appeal site at 3 Moorhill Road comprises a two-
storey semi-detached house in a residential area which has an existing rear and
side extension and a conservatory to the rear. The proposed development would
replace the conservatory with a single storey extension.
4. The proposed extension would extend approximately 4 metres from the rear
elevation of the existing dwelling and would be single storey with a very shallow
pitched roof. The proposed extension would run across the width of the property
from the shared boundary with No 5 to the side wall of the existing side and rear
extension.
5. The Council’s Residential Design Supplementary Planning Document 2018 (SPD)
includes Figure 18 on the 45-degree rule for single storey extensions. It expects
that if a 45-degree line were drawn from the centre point of the nearest adjacent
ground floor window of a habitable room on the original rear wall of the
neighbouring property, the proposed extension would not infringe that line. The
SPD seeks to protect living conditions of neighbouring occupiers and as such,
development that does not comply may be considered to have an unreasonable
effect on them, but individual site circumstances should be considered.

6. The proposed extension would project beyond and include the footprint of the
existing conservatory. The existing conservatory breaches the 45-degree line, and
the proposed extension would also infringe the 45-degree line.
7. While the existing conservatory has significant amounts of glass it is nevertheless
a bulky structure. The roof of the proposed extension would be lower than the
existing conservatory’s roof at its highest point. The orientation of the properties is
such that the proposed extension would be on the northern elevation and therefore
any additional effect on either daylight or sunlight levels would be limited. With
regard to outlook, the proposed roof design and lower maximum height would limit
any effect. The existing conservatory is already close to the close boarded
boundary fence. Consequently, the proposed extension would not be of a scale
that would be overbearing or oppressive and would not result in a detrimental
effect on outlook.
8. Notwithstanding that the proposed development would not accord with the SPD, I
conclude that the proposed development would not cause harm to the living
conditions of the occupiers of 5 Moorhill Road with regard to light and outlook.
Therefore, it would not be contrary to Policy BE3 of the Warwick District Local Plan
(adopted 2017) (Local Plan) which seeks to avoid any unacceptable adverse
impact on the amenity of nearby uses and residents as a result of development.
Protected species
9. The Conservation of Habitats and Species Regulations 2017 (as amended)
impose a duty on me to consider whether protected species would be affected by
the development and if so whether associated mitigation measures would be
effective.
10. Requirements for surveys should be proportionate. Warwickshire Council
Ecological Services has advised that there are records of bats in the area, the
surrounding habitat provides roosting and foraging opportunities and potential
roosting features for bats are visible. While the proposed development would not
have a significantly greater footprint than the existing conservatory, the proposed
development would both remove the existing conservatory and abut the existing
building which would have the potential to have a detrimental effect on a protected
species at roof level.
11. Paragraph 99 of the Office of the Deputy Prime Minister Circular 06/2005 states it
is essential that the presence or otherwise of protected species, and the extent
they may be affected by a proposal, is established before planning permission is
granted. Surveys can be carried out under conditions attached to a planning
permission, but this should only be done in exceptional circumstances. No
preliminary ecological survey has been provided indicating the presence or
absence of bats and/or any appropriate mitigation measures. Furthermore, there is
no evidence before me suggesting there are exceptional circumstances in this
case.
12. Although the appellant has offered to commission a brief ecological appraisal, the
appeal process should not be used to evolve a scheme and there are no
provisions for amendments or further documents to be submitted. It is important
that what is considered at appeal is essentially the same scheme that was
considered by the Council and by interested parties at the application stage.

13. Therefore, it has not been demonstrated that the proposed development would not
have an adverse impact on protected species. As such there is conflict with Policy
NE2 of the Local Plan which seeks to ensure that development likely to impact
rare endangered or priority species will be subject to ecological assessment.
Additionally, this would be contrary to the precautionary approach set out in
Circular 06/2005, section 15 of the National Planning Policy Framework (the
Framework), and the Natural Environment and Rural Communities Act 2006. I give
this matter significant weight.
Other Matters
14. I note the appellant’s assertion that the proposed extension would replace the
existing conservatory with a high quality thermally efficient living space in a
sustainable way by using the existing developed footprint. This would be a benefit
of the proposed development, to which I have given moderate weight. The
appellant indicates that these benefits can be achieved without causing harm to
the occupiers of the neighbouring property, which I have found to be the case, but
this weighs neutrally in the planning balance.
Conclusion
15. In conclusion, notwithstanding my findings on living conditions and the benefits
outlined by the appellant, it has not been demonstrated that the proposed
development would not have an adverse effect on protected species. Accordingly,
the proposed development conflicts with the development plan as a whole and
there are no material considerations of sufficient weight to indicate that a decision
should be taken otherwise than in accordance with it. Therefore, the appeal is
dismissed.
