Brits are somewhat opposed to "tower blocks" because they were a poorly-planned top-down social engineering experiment in the postwar years to deal with rehousing the residents of slums and other deprived areas. Modern "high-end living" flats in much taller, aesthetically pleasing, and most importantly: safer, structures are being built, but not at a sufficient pace.
A reasons there hasn't been a total crash yet is because lovely, lower-density houses (think: 3 and 4 story spacious townhouses, not working-class 2-up/2-down terrace houses) are bought up for millions then internally gutted and remodelled into individual, modestly-sized flats to rent - sometimes barely larger than the size of a living room.
