I have fewer problems with 5 over 1s because they’re not tall office buildings and fire crew ladders will reach top floors easily. They are easy to evacuate and easy (comparatively) to do rescue in.

I watched Grenfell happen and everyone in London had to see its covered up remains every single day for years. I don’t want to see it happen again.

And Grenfell WAS designed with residential standards, each apartment a unit that fire could not escape from, only cladding caused its spread via the exterior of the building. My big concern with interior walls is that they won’t put up proper units that are designed to contain the fire, and that the floor/ceiling aren’t able or designed to contain the fire in apartment units either. My feeling is that they’ll just put up paper thin divider walls and call it a day.
