Appeal against an enforcement notice for a rear dormer roof extension
Receiving an enforcement notice requiring the demolition of a newly built extension is one of the most stressful situations a homeowner can face.
In this case, our clients were served with an enforcement notice requiring the complete removal of a rear dormer roof extension that had already been built, at significant cost, and which they believed was lawful.
The background
The homeowners had constructed a rear dormer roof extension to their house. This is a very common form of development and, in many cases, does not require planning permission because it is permitted development.
However, permitted development rights are subject to detailed conditions. One of those conditions is that a dormer must not exceed the height of the existing ridge line.
During construction, the ridge height of the roof was raised slightly — by only a small amount — as a result of the insulation build-up and finishing materials. This change was not intentional and was not something the homeowners were aware of at the time.
Although the difference was barely perceptible from the street, the council took the view that the development was no longer permitted development and served an enforcement notice.
The enforcement notice
The enforcement notice alleged that the rear dormer and modest increase in ridge height harmed the appearance of the house and the wider street scene.
Rather than requiring a limited alteration, the notice demanded that the entire dormer be removed and the roof rebuilt to its former profile.
This came as a huge shock to the homeowners. They had spent their savings on the extension, had not set out to breach planning control, and simply could not afford to demolish the works and start again.
The enforcement appeal
We appealed the enforcement notice on the homeowners’ behalf.
The appeal focused on the fact that the change to the ridge height was very modest, difficult to perceive from public viewpoints, and caused no harm to the character or appearance of the street.
We explained that the street already stepped up and down naturally because of the slope of the land and that small variations in ridge height were a common and established feature.
We also pointed out that rear dormer roof extensions were widespread in the surrounding area and that the development sat comfortably within that context.
Crucially, we demonstrated that requiring the complete demolition of the dormer was wholly disproportionate to the very minor planning issue identified.
The decision
The planning inspector agreed.
The appeal was allowed, the enforcement notice was quashed, and planning permission was granted for the dormer roof extension as built. The homeowners were able to keep their extension and avoid demolition entirely.
This outcome saved them from significant financial loss and brought a deeply distressing situation to an end.
Why this case matters
This case illustrates how easily homeowners can find themselves facing enforcement action after making what appears to be a very minor and technical mistake.
It also shows that enforcement notices — even those requiring demolition — can often be successfully challenged where the alleged harm is overstated or where the council’s response is excessive.
If you have received an enforcement notice relating to a dormer roof extension, early specialist advice is critical.
