This is one of several successful appeals we have handled following refusals of planning permission for dormer roof extensions. For advice on what to do after a refusal, see our guidance on refused planning permission for dormer roof extensions.
When Mr Jobanputra contacted us in late 2024, he had already been trying to secure permission for extensions to his house in Croydon for several years and had experienced a series of frustrating setbacks.
The most recent refusal related to a dormer roof extension. The council’s sole reason for refusal was an alleged impact on the neighbouring property at 1 Grimwade Avenue, citing visual intrusion and a loss of privacy.
That refusal was particularly difficult to accept. A similar dormer had been granted permission in 2018, the current proposal was significantly smaller than a scheme refused in 2022, and the case officer had actually recommended approval. Despite this, the planning committee voted to refuse the application.
Our appeal focused on the inconsistency of the council’s position and the lack of clear evidence to support its concerns.
A key part of the case was precedent. We highlighted the earlier approval for an almost identical dormer and pointed out that there had been no material change in planning policy since that decision. In planning, consistency matters. If a council departs from its earlier decisions, it needs to explain why. In this case, it had not done so.
We also emphasised that the proposal represented a clear reduction from the refused 2022 scheme and was very close in scale to the previously approved dormer. This improvement was not acknowledged in the refusal.
The main issue, however, was the alleged impact on neighbours. This is a familiar theme in householder appeals, particularly for dormer extensions, and it is often where councils rely on broad judgement rather than detailed analysis.
Our view was that the dormer and rooflights would not cause any unacceptable harm. Using satellite imagery and measured drawings, we showed that the new bedroom window would look primarily down our client’s own garden, with only limited and awkward oblique views towards the neighbouring property. We also demonstrated that the neighbouring house was designed with its main windows facing away from the appeal site and that an existing first-floor window was in fact closer to the neighbour than the proposed dormer window.
Concerns about visual impact were dealt with in a similar way. The dormer was set well in from the roof edges, positioned below the ridgeline and partially screened by mature boundary planting. In our view, it would read as a modest and subservient addition rather than an intrusive feature.
The inspector agreed.
The appeal was allowed in April 2025, with the inspector concluding:
“The proposal would not harm the living conditions of neighbouring occupiers with regard to privacy and outlook.”
The inspector went on to find that the bedroom window would result in only “oblique, rather than direct views”, that the massing and siting meant the dormer would not be “obtrusive, imposing or overbearing”, and that the extension would be of an appropriate scale to remain subservient to the host dwelling.
This case highlights how often refusals of dormer extensions turn on generalised concerns rather than demonstrable harm. Even where a planning committee overturns an officer recommendation, a carefully prepared appeal, supported by clear evidence, can succeed.
Although this was an appeal in Croydon, the same issues arise repeatedly in other boroughs. We deal with dormer appeals regularly as part of our wider planning appeals work in Croydon.
Our CEO, Martin Gaine, has written about some of our successes with dormer appeals in the Telegraph newspaper – the latest articles are here and here.
If you have been refused planning permission for a dormer roof extension, it is often worth taking advice before abandoning the proposal.
