Outside London, there are masses of privately owned properties that are empty or derelict. Some have even been partially or completely demolished in preparation for planning permission which was never granted.
Factory buildings, hospitals, pubs, churches, flats, old shops and houses. Nothing is exempt.
Some are owned by property developers who may or may not live in the area, some are owned by private individuals who are unwilling or unable to sell on and some are council owned.
The sheer waste is just soul destroying.
Listed properties are being held hostage by developers who want to convert to profitable HMOs and the councils are happy to let swathes of their borough become derelict eyesores.
There's no need to develop green belt land outside of London, there's plenty of brown field sites going spare.
There are many causes of homelessness and simply putting thrm under a roof will not stop the problems.
Drugs, mental illness, personality disorders, lack of mental capacity, abuse, habitual criminality; you name it there are dozens of factors that have to be tackled, before some of the homeless can stay off the streets.
Simply compulsorily buying 10,000 homes and sticking rough sleepers and those in temporary accomodation into them is not enough. It will never be enough.
