Unequivocally, No. Having had detailed experience of the process for several years while on the Town Council, extensions normally get waved through unless they are seriously out of keeping with the street scene, or represent gargantuan over-development. I believe the LGA have confirmed this.
It is simply naive or disingenuous to pretend this will make a ha’peth of difference to the economy. As the LGA has said, there is a massive backlog of extensions which have been given permission already, but which the owners have not bothered to build yet (perhaps because they need money to do so).Tweet
