Experts say housebuilding has become so alarmingly bunged up for a number of reasons, some external and unavoidable and some entirely self-inflicted. Tim Craine, the founder and director of Molior London, said: “When it comes to London housebuilding, all the stars are aligned in exactly the wrong way. The cost of bricks and mortar is inflated, the costs of labour is inflated, interest rates are also inflated, there is all manner of inflation. When the costs are all stacked up like that there is nothing left in the margin to be divvied out.”
