My brother lives in Jaywick, in a road not unlike the one in the pic posted upthread. The bit where he lives (possibly called Brooklands, all the streets are named after car manufacturers) is like some sort of South African township, but full of white people.
The houses are of non-standard construction. They don't have foundations, they're sort of built on brick piers. After my brother's purchase completed, he found he didn't have any water. When he checked it out, robbing bastards had nicked all the copper pipe from underneath the house. He got a grant to improve the heating and stuff, and it included the provision of a warm air heat pump thingy. It was nicked from the wall of the house when he was in hospital. He won't stay away overnight now for fear of the place getting trashed.
The council can't do anything about the roads, because the roads haven't been adopted by the council and are still "owned" by whoever built the development. They can't find out who's responsible and don't have the resources to compulsorily purchase. The whole place is in some sort of legal lacuna and that's why attempts at regeneration keep failing. When my brother bought the place, his solicitor told him that if it burned down or collapsed, he wouldn't be allowed to rebuild because of some covenant or something.
While it's not all as bad as where he is, there's fuck all there apart from a beach, a chinese takeaway, a dodgy looking pub and a couple of convenience stores. There's a lot of crime, a lot drug problems and many owners lease the houses to the council, who use them as temporary accommodation for homeless people.
And there are concerns about flooding. The sea has overtopped the sea wall a few times, and started coming up the street.
I wouldn't move there if you paid me £140k to move. It's bad enough going there for a day now and again to see my bro.
Don't do it, OP.
