I mean kinda.
But a _lot_ of council estates were well designed, but suffered from failed assumptions. The underground parking in the barbican for example was the same design that cause so many issues for estates elsewhere. They were hidden and that meant crime, unless there was tight access control.

Like most estates at the time, the three bed flats had an upstairs. Not only that, they were bright! Had a balcony.
The difference between the trellick and the barbican is the barbican had middle class people growing plants on the balcony. Until the hipsters moved in, the trellick just had shit.

I think the biggest thing to take away is that for a long while council housing _had_ to be better than private. It was partly slum clearance, partly vote winning, partly "you fought for this in the war" https://en.wikipedia.org/wiki/Parker_Morris_Committee has the general plan.
Separate kitchens, storage, decent square footage, working heating as a _minimum_ something which even 500k flats struggle to do now.
