Sorry but the OP makes a good point. She is I thikn trying to point out that it is a complex problem and not just a "build more houses" situation.
The housing crisis is real in terms of the individual - Family A needs a house in the area they live in and there is neither social housing availble nor affordable accommodation (rented or properties to buy).
That situation has been exploited by government and big business to allow HUGE developments in swathes of countryside and "pop-up" dwellings in gardens and garages for people. STill nothing affordable for poorer people though - great for "investors".
I live in London and every square inch is being built on. What were garages, roof spaces, gardesn, small businesses, railway embankments, sports pitches - you name it - it ihas been built on. There are not enough school places or road space, GPs or dentists - and yet they keep building and people keep buying.
According to the BBC yesterday the net immigration to the UK was 318,000 in 2014. - All need a home. We cannot build another 318,000 houses here - and the same in 2015. Also foreign investors are actively encouraged to buy land in the UK - and never live here - expecially in London.
Yet this is not discussed in the context of housing. (It makes you a racist to mention it)
In the meantime there are houses that are empty in areas other than the South East and the major cities which would be affordable if there were jobs.
That does not mean that there is not a crisis for individual families - there is - myself included - but there is not a national shortage - it is an excuse to misdirect people.
