For a year and a bit I lived in a flat off the Walworth Road, and every morning and evening I would walk the half a mile between Elephant & Castle tube station and home. On one side was the “mugger’s paradise” Heygate Estate, on the other, the Carbuncle Cup-winning Strata SE1 . For many reasons, I always preferred the look of the former over the latter.
At the time I’d heard there were only seven people left living in flats there, and the mostly-derelict estate was probably mostly known to non-locals as a setting for films  like World War Z and Attack The Block, and the TV shows Luther and Spooks. Steel panels went up, over time, to stop the curious from taking walks around the abandoned buildings, or enjoying the views from the roofs. The Heygate may have still been a home for some, but the world outside treated it as a dead space. Photographers, explorers, and free runners loved it.
For everything that’s wrong with London’s housing and built environment, look to the Heygate Estate, and to what will replace it. Completed in 1974, its 1,200 homes housed more than 3,000 people in spacious, well-lit rooms with all the modern conveniences. Two decades later, its broken lifts, broken lights, piss-soaked corridors and violent crime came to signify everything wrong with the post-war approach to social housing and urban design.
Of course, the reality of what the Heygate was is more complicated than a concrete monstrosity taken over by the allegedly degenerate. Listen to Chris Wood’s “Heygate Heaven”, for example - the voices of residents drift in and out over the the ambient sounds of the estate and surrounding areas. Many of the residents mourn its destruction, even while admitting its flaws:
Adrian Glasspool is the last person living within the Heygate, and the Guardian dealt with his imminent eviction  this week:
Glasspool, a teacher, who remains inside his three-bedroom maisonette in Elephant and Castle amid a dispute about compensation, represents the last hurdle in a 15-year project which will see more than 1,200 primarily social-rented homes replaced with more than 2,300 flats and houses, the majority sold for prices currently reaching £380,000 for a one-bedroom flat.
Southwark council, masterminding the transformation with developers Lend Lease, says the scheme brings long-overdue regeneration to an area long blighted by poverty and post-war brutalist housing, and that money it generates will finance thousands of affordable homes.
None of these 284 homes, currently priced between £350,000 and £1.1m, will be offered at a discount. Instead, Lend Lease has given Southwark £3.5m to spend on social housing elsewhere and will contribute to a new leisure centre.
A report by council officers said Lend Lease baulked at providing social units as this would require a second lobby and lift shaft to separate the two types of resident, adding: "Not doing so would have significant implications on the values of the private residential properties.”
That last bit is particulalry horrible, as it reveals the base motivation for the project - maximising profits from the redevelopment, and doing so by keeping the riff-raff out. Developers across the city have been doing this, with gates within gates  to make the division especially clear.
The simplest way to get across how terrible a deal this is for everyone involved in the Heygate's regeneration is to simply quote the figures involved:
- Price paid by Lend Lease for 22-acre Heygate Estate site : £55m
- Price paid for nearby Oakmayne/Tribeca Square 1.5-acre site : £40m
- Expected total cost to Southwark Council for evicting residents : £65.5m
- Previous estimate of cost to refurbish Heygate Estate to modern standard: £35m
- Expected profit from sales for Lend Lease : £194m
- Expected profit from sales for Southwark Council : £0
- Average compensation given  to leaseholders of one bedroom flat: £95,480
- Average compensation given to leaseholders of four bedroom flats: £177,421
- Lowest price unit  in new development (one bedroom flat): £310,000
- Number of social-rented units in Heygate Estate : 1,200
- Number of social-rented units in new development : 79
What has happened here is that Southwark Council has lost money on evicting the Heygate Estate for the benefit of Lend Lease, with no prospect of getting anything in return for it. In the process, an established community has been scattered throughout the borough and beyond, while the Council obfuscated what was happening  and fought to keep key details secret  until it was too late to stop it.
There is a thriving microblogging community in Southwark, and it has documented every step. Sites and groups like 35 Percent , the Elephant & Castle Urban Forest , and Better Elephant  have been covering the cleansing of Southwark to no avail. 35 Percent has actually managed to create (thanks to FOI) a map of the Heygate diaspora :
The Heygate Estate occupied a large site next to a major transport interchange in an inner London borough, and its residents had the temerity to remain poor while the land they lived on became more valuable. When people talk about the "social cleansing" of London, this is it. The classism and snobbery directed towards brutalism (but only when occupied by certain groups - see: the Barbican) compounded the Heygate Estate's fate. Read through the stories from former residents, archived on Heygate Was Home , for proof that it wasn't always considered a slum, or an eyesore, by the people who mattered.
We're losing London to the forces you can see at work at the Heygate. Regeneration schemes that push the existing community out to neo-banlieues and replacing them with white collar professionals and students living in inferior-quality buildings; councils pleased to turn a blind eye so they have higher rate payers within their boroughs; developers getting given land at a fraction of its true value on the promise of future profits that mysteriously never arrive; a revolving door  between local authorities and regeneration consultancy and PR firms. The people affected by these phenomena are the last people to be given a say in, let alone be given control of, their lives. God forbid they should ever be given a way to choose how their city changes, too.
