Just because money was spent it doesn't mean it wasn't austerity. It could have been that to have the building to a safe standard it would have cost £12m but only £9m was approved due to austerity for example.
practically everything could have 'more money spent on it' to make it 'safer' the guidelines for the acceptable standard are the building regs in this case. Money supply is in practice finite and choices have to be made ....and is not then only consideration people want a nice comfortable environment as well
