What about these pools? Anyone fancy a swim?
Yes, exactly. There is a lot of physics involved when a building is designed, lots of equations and lots of rules at the design stage. Then at each stage the Building inspector has to make sure it's safe before the next level can be worked on.
I do not like heights but a building cannot be sold without safety checks. No idea about how Grenfel was so bad but many council blocks are not adequately maintained- and also with Grenfell the problem was the flammable but probably cosmetic coating that the council had added, rather than the structure of the building.
