There is a huge amount of building going on in my area, the infuriating thing about it seems to be that its all "luxury" apartments, and even then the builders seem to have been able to get out of building the original number of affordable rent places.
It would be good if the Government would do some house building to make up for the massive under supply over the last 30 odd years, and that of course is the position we are in. Housing is so exepnsive because since right to buy the supply of housing has been in the hands of the private sector, which is risk averse so won't build as much as is needed in order to maximise profits. Successive governments are to blame, and there needs to be a solution.
The issue with it will be, that if supply is increased many people will see the value of their properties fall and be in negative equity, so no political party will do it.
The knock on effects of this under supply are amazing, lower levels of consumer spending (as more is spent on rent/mortgages), causing less investment from firms and the concequent knock on.
Housing becoming an investment business, buy to let, buy to leave, etc etc. More and more money borrowed to invest in this market rather than into other business oportunities.
Rents rising causing the HB bill to rise, causing jealousy over the amount people recieve in benefits. Increased ghettoisation of areas.
Its very interesting, housing has been at the heart of British policy for over 100 years. We are still getting it wrong.
