Developers want to build on top of my flat and there’s nothing I can do to stop it

Your article on the National Leasehold Campaign highlighted the financial injustices of leasehold ownership, but there is another growing problem that deserves attention: rooftop development on occupied blocks, which was highlighted also by a letter published in response to the article.

I am a leaseholder in north London and planning permission has been granted for additional storeys to be built on top of our building. Like many leaseholders, I bought my flat believing that I had security in my home, only to discover that the roof above it could later be treated as a development opportunity over which I had virtually no control.
