The London Borough of Islington has fined a landlord £280,000 for defying orders to rip down insubstantial housing built without permission in an outbuilding. 

It's good to see a London council getting tough on landlords who flout planning law to the detriment of their tenants. Too often we see local authorities not taking action when there is a breach of planning law, or being thwarted by the four-year dwelling rule which exempts the landlord if the dwelling has been continuously occupied for four years.

Islington Council has shown that you can forcefully take on those who are ignoring planning regulations with the right political will. This is as much an issue of ensuring that tenants live in decent, spacious and well-kept properties as it is simply a planning dispute and Islington has recognised this in the work it is doing in the private rented sector.

And that colossal fine could go towards building some real houses.
