Your last editorial had a number of good suggestions for increasing the rate of housebuilding. I have another – easier removal of covenants restricting development. I have a large site adjacent to my house that has planning permission for a detached house. My neighbours have a covenant that restricts each plot to a single house.

To remove this requires a lengthy legal process with no guarantee of success despite generous compensation. I would be interested to know how much development is prevented by such covenants and what increase in the rate of housebuilding would result from allowing planning permission to override them.
