I may sound like a nutter here and i know it would mainly depend on funds, but i came up with an idea to improve various suburbs/new housing areas being built in Liverpool.
The idea is to build 'hotel ish' flat blocks but affordable for working class residents, Not exactly like the one imaged below but very similar in design. Various areas in liverpool which are run down etc can be flattened or rebuilt with these apartment blocks. They will also feature a small park area and a car park.
As said, it would cost money and work but at the end of the day will be a big improvement to liverpool. Even some modern flat blocks in eastern europe are designed like this and thought we should have somthing like this in merseyside. If they can manage to develop areas like that, why dont we?
