Sevenoaks District Council appeal findings
Sevenoaks design: roof form, frontage and fencing
The selected examples lean more toward dismissed appeals than the matched local set.
Counted against appeals
Roof form, comparable homes and fence harm
Pitched roof made the extension bulky
Meeting the side hip near its centre emphasised height and made the roof form look alien. Painted render or cladding did little to reduce the harm.
Previous approvals were not close matches
The cited properties differed: one was detached and another had a more horizontal, proportionate extension. The Inspector assessed this proposal on its own merits.
Fence harm is not explained
For the fence and gates, the Inspector concluded there would be unacceptable harm to the locality’s character and appearance.
Helped or needed
Frontage variation and matching house form
Form and materials followed the house
The extension would respect the dwelling’s form and use matching materials. The Inspector found the finished building well designed.
The frontage kept its variation
It would reach the southern boundary, but the adjoining building stood further forward, leaving variation along the frontage.
Your refusal notice
Check these details
- Does the refusal say the roof form makes the extension bulky?
- Are the cited approved extensions truly comparable in type and proportion?
- Would the proposal retain variation along the frontage beside neighbouring homes?
Detailed selected reasoning mainly covers extensions, and the fence conclusion offers no design detail. These decisions do not predict another result.

Development described in the decision
described in the application form as follows: “The proposal is for the erection of a two-story side extension extending out 2.7 meters to the side and a single-story infill between the house and garage proving an extended lounge and office, new utility room and bathroom on the ground floor and one bedroom and bathroom on the first floor. A porch is also proposed measuring 1.3 meters deep”.
Issue identified by the Inspector
The main issue to be determined in this appeal is the effect of the proposed development on the character and appearance of the host building and its surroundings.
Paragraph 3 · Source page 1
Reasoning from the decision
The proposed extension would respect the form of the existing dwelling, using materials to match. It would extend to the southern boundary of the plot but the adjoining building is sited forward of number 20 and there would still be some variation in the rhythm of the buildings along the frontage. In this case, I am convinced that the proposed extension does not need to be “subservient” to the original structure, in order to achieve a satisfying finished design. The finished building would be well designed architecturally, while interest would be maintained in the streetscene and the overall harmony of the townscape would be preserved. Although views towards trees at the back would be more limited, this concern does not justify a refusal of planning permission, in my opinion.

Development described in the decision
a first floor side extension.
Issue identified by the Inspector
The main issue is the effect of the proposal on the character and appearance of the area.
Paragraph 4 · Source page 1
Reasoning from the decision
The proposed pitched roof which would meet the existing dwelling’s side hip roughly towards its centre, emphasising the proposal’s height. The roof form would be alien to the dwelling, and surrounding properties on [address]. It would complicate the simple form of the existing building in a prominent location. This would result in a bulky addition that fails to integrate with the existing pattern of buildings, spaces and roof forms. This would cause harm to the character and appearance of the building and streetscene, for which the use of either painted render or cladding finishes would provide little mitigation.

13 January 2022 · Dismissed
Development described in the decision
for part single, part two storey, rear and side extensions.
Issue identified by the Inspector
The main issue is the effect of the proposal upon the character and appearance of the existing building and the surrounding area.
Paragraph 2 · Source page 1
Reasoning from the decision
I conclude therefore that the proposed development would have a detrimental effect on the character and appearance of the existing building and the surrounding area. Accordingly, I find conflict with Policy EN1 of the [name] and Development Management Plan Development Plan Document 2015, Policy SP1 of the Sevenoaks Local Development Framework Core Strategy (2011) and the Sevenoaks Residential Extensions Supplementary Planning Document 2009, all of which seek to ensure high quality design which does not harm the character or appearance of the area.

12 July 2022 · Dismissed
Development described in the decision
described as “first floor extension”.
Issue identified by the Inspector
The main issue raised is the effect of the proposal upon the character and appearance of the existing building and the surrounding area.
Paragraph 2 · Source page 1
Reasoning from the decision
I have also noted the reference to other properties in [address], that gained permission for an increase in ridge height, notably at Nos. 4 and 34. It is clear that the Council gave weight to retaining the existing form of the property when considering upward extensions and concluded that they would not harm the character and appearance of the area. However, the circumstances here are different. No. 4 is very different being detached, and thus is more proportionate to the size of the host property given this. No. 34 is similar, also being semi-detached, but the extension provides a more horizontal emphasis, which appears more proportionate to the existing building in that case. Furthermore, these examples do not provide an overriding influence over the style of dwellings, and I have considered this proposal on its merits in the context of the site.

1 April 2025 · Dismissed
Development described in the decision
the installation of boundary line fence and gates.
Issue identified by the Inspector
The main issue is the effect of the proposal on the character and appearance of the locality.
Paragraph 3 · Source page 1
Reasoning from the decision
For the reasons given above I conclude that the appeal proposal would have an unacceptable adverse effect on the character and appearance of the locality. Accordingly, the appeal is dismissed.
