The answer seems obvious but, as thermal efficiency expert Fergus Nicol says, once global warming and energy conservation are factored in, the solution to the housing crisis is more complicated.
The shortage of housing, particularly for people on low incomes, is a major issue. The extent of the shortage is made visible by the number of homeless people forced to sleep rough on the streets. According to research by the housing charity Shelter, at least 320,000 people are homeless in Britain, with more than 4,000 of these sleeping rough. The need for council housing vastly outstrips supply, with around 1.24 million UK households on local authority waiting lists.
