Appeal Decision
Site visit made on 21 May 2026
by David Cross BA(Hons) PgDip(Dist) TechIOA MRTPI
an Inspector appointed by the Secretary of State
Decision date: 12 June 2026
Appeal Ref: 6001348
145 Berry Hill Road, Mansfield, NG18 4RT
• 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 Miss Klaudia Dziak against the decision of Mansfield District Council.
• The application Ref is 2025/0482/HHA.
• The development proposed is: Single storey side extension with existing garage conversion. Two
storey rear extension, with loft conversion.
Decision
1. The appeal is dismissed.
Main Issues
2. The main issues are the effect of the proposal on the:
• Character and appearance of the host property and the area; and
• Living conditions of nearby residents with regards to privacy and outlook.
Reasons
Character and Appearance
3. The appeal site consists of a detached dwelling with a large garden located in a
pleasant suburban area. The site is a corner plot close to the junction with Berry
Hill Road and Berry Hill Lane. Due to this corner location, the appeal site is in a
prominent position in the streetscape, including views of the side and rear of the
property.
4. The appeal proposal includes a substantial 3-floor rear extension. This includes
full-height windows on the ground and first floor which do not respect the design of
the windows of the host dwelling. The arched features of the first floor windows are
also of an incongruous appearance compared to the windows of the host dwelling.
Although nearby dwellings include arched design features, these are most
commonly associated with entrances and do not establish a context for the
prominence and number of these features on the appeal proposal.
5. The proposal also includes a number of box-like additions at roof level which
would jar with the hipped roof design of the host dwelling. The level of the flat
roof/wrap-around balcony also projects above the eaves of the host dwelling,
which adds to the disjointed appearance of the proposal. The roof extensions
would also be of a significant scale and bulk which would dominate the roof of the
dwelling and would appear as disproportionate additions. The wrap-around

balcony at roof level would also be out of character for this area. Although the roof
extensions would not project above the highest ridge of the existing roof, this
would do little, if anything, to mitigate for their unacceptable design and scale.
6. The use of materials such as a rendered finish and standing seam cladding on an
extension of this scale would also contrast uncomfortably with the traditional
materials on the host building and the wider area. Although the use of contrasting
materials such as render may be acceptable in some circumstances, in this case
the materials add to the clumsy and disjointed appearance of the proposal.
7. The proposed extensions would overwhelm the vernacular design of the host
building, and would be visually incongruous compared to the traditional suburban
character of the area. This harm would be exacerbated due to the prominent
location of the site.
8. Drawing the above together, the design, scale and prominence of the proposal
would lead to significant harm to the character and appearance of the host
property and the area. The proposal would therefore be contrary to the character,
appearance and attractive development requirements of Policies P2 and P6 of the
Mansfield District Local Plan 2020 (the Local Plan). The proposal would also be
contrary to the National Planning Policy Framework (the Framework) regarding
achieving well-designed places.
Living Conditions
9. The proposal would include a balcony at the loft floor level extending around 3
sides of the rear extension. Due to the elevation of the balcony and the viewing
angles it would enable, this would lead to an intrusive degree of overlooking of the
rear gardens and windows of neighbouring properties on Berry Hill Road. Although
the balcony would be set back from the site boundary, this would not be sufficient
to overcome the intrusive degree of overlooking arising from the height of the
balcony and the extent of views it would provide.
10. It may be possible to erect a screen on the balcony to prevent overlooking. But this
would appear as an incongruous feature at roof level and would exacerbate the
harm arising to character and appearance.
11. Windows and glazed doors on a side elevation at the first and loft floor levels
would also enable intrusive overlooking of the rear gardens of neighbouring
properties. The appellant has submitted amended plans removing these features,
but this would not address the loss of privacy arising from the balcony.
12. The rear elevation of the host dwelling is set further beyond the main rear
elevations of the neighbouring dwellings, and the rear extension would project
significantly beyond this. The site also slopes down to the rear which would
exacerbate the prominence of the rear extension. When combined with the height
and bulk of the proposal, these factors would mean that the rear extension would
have an unacceptable overbearing impact on the outlook from the rear of
neighbouring dwellings. That would be the case even allowing for the setback of
the rear extension from the site boundary and the intervening existing garage.
13. The Council has not referred to overshadowing or loss of light in its reason for
refusal, and I have had regard to the Sun Study drawings submitted by the
appellant. However, a lack of objection in relation to light does not lead me to a
Appeal Decision 6001348

different conclusion in respect of the effect of the proposal on the outlook from
nearby properties.
14. For the reasons given above, I conclude that the proposal would lead to significant
harm to the privacy and outlook of nearby residents. The proposal would therefore
be contrary to the residential amenity requirements of Policies P6 and P7 of the
Local Plan. The proposal would also be contrary to the Framework which seeks to
achieve a high standard of amenity for existing and future users.
Other Matters
15. Reference has been made to a 2-storey side extension at 127 Berry Hill Lane
which is a similar corner plot opposite the appeal site, and which the appellant
contends is of a similar volume as the appeal proposal. However, although the
extension at No 127 is relatively large and has extensive areas of glazing at both
ground and first floor level, it is of an understated design compared to the appeal
proposal and is subordinate to the host building. The bulk and massing of the
extension at No 127 is also of a lesser degree compared to the appeal proposal.
Although there is extensive glazing on the extension at No 127, this is of an
understated appearance and is located so as to mitigate potential loss of privacy to
nearby properties. The circumstances of No 127 are therefore materially different to
the appeal before me. I have also been referred to other examples of buildings and
extensions, but it has not been demonstrated that the circumstances of those sites
are a direct parallel to the appeal proposal. In any event, I have determined this
appeal on its own merits.
16. The appellant sets out that the proposal would improve family accommodation,
reduce the need for relocation and would enhance the property’s longevity.
However, these benefits could be achieved by extensions of a more appropriate
design and in any event would not outweigh the significant harm I have identified.
17. I note the frustrations expressed by the appellant in relation to the advice from the
Council and the decision process leading up to this appeal. However, this is not a
matter for this appeal which I have determined on its planning merits.
Conclusion
18. For the reasons given above the appeal should be dismissed.
