At the time of the "regeneration" (2000s) it was a toss up between a number of estates and the heygate. However because of its size and location the heygate was chosen
My estate was turned around, and I was lucky enough to live in the estate, not on it. I got to know some of the original residents(and still do).
There are two important things to note, Council housing is almost exclusively of a very high standard (bigger than new builds by ~10+ sqm) Compared to the slums described so vividly in the road to wigan pier, a paradise. (running toilets, windows, heating plaster, enough bedrooms for each kid)
Until a rule change in the late 70s, you had to have a job to be eligible for council housing. There were (and still are, more or less) residents associations that look after the running of the estate. Caretakers lived on site, towers had 24 hour concierges, and ne'dowells were evicted.
However, that was all taken away in favour of dumping problem families, outsourcing cleaning and upkeep (In some cases, one cleaner 2 hours a day costs something line £80k annually.)
In short, there is nothing wrong with the estate fabric (of the surviving estates) but how they are looked after, and who lives there. Grenfell is a shining example, a solid block that was subdivided and halfarsedly put in new gas mains.
Asking as someone mostly ignorant of estate housing: what does this distinction imply/represent?
When it came to regeneration/improvements, we were the one consulted, not the private renters.
If I missunderstood your question, here is some waffle:
An estate is a logical collection of dwellings, normally flats (but can be houses) that were commissioned and built by local governement for the express purpose of housing the employed working classes.
for example my estate was made up of four blocks of about 180 flats. Each block encloses a shared garden, with childrens play equipment.
as to what they look like:

On one hand, I'm sure I would hate living in a city where everything looked like the Barbican. Yet, every time I'm there I'm awed by its strange beauty. It has such a strong identity.. it feels like walking inside a sculpture.
I think that different kind of "organic" is why I love Barbican. There aren't many places that make me feel like a child exploring a new area, but Barbican is the best at that.
