Comment from an old reddit post:

Ashfield Valley estate in Rochdale. It was completed in 1969 and while it was initially popular, like many housing estates at the time, it quickly declined and by the 1980s was a haven for drug users, glue sniffers and squatters as well as being home to a large number of families, OAP’s and single people. In January 1987, frozen water pipes cracked, flooding 15 of the 26 blocks. Many of the tenants were evacuated, with some having to sleep in a local church. 23 blocks were demolished in 1992.
