As a child of 70s Britain, Brutalism was the future, or at least it was on Doctor Who and Blake’s Seven so I’ll always have a soft spot for a large blocks of looming concrete, particularly if juxtaposed with features of the natural landscape.
The deterioration concrete suffers from can be dealt with, the decline of the buildings from the 60s & 70s was down to the quality of the building and larger socio-economic factors, not the physical design or an insurmountable inherent fault of concrete itself - the world’s largest unreinforced concrete dome is doing fine almost two millennia after it’s construction after all.
