Planning threat to grandparents - Telegraph The minister, who is regarded as close to David Cameron and George Osborne, added that it was simply "immoral" that young people had to wait for so long to save a large enough deposit to buy a home. In his speech, Mr Boles will say: "I am afraid that we have a simple choice. We can decide to ignore the misery of young families forced to grow up in tiny flats with no outside space. We can pass by on the other side while working men and men in their twenties and thirties have to live with their parents or share bedrooms with friends. We can turn a blind eye while Margaret Thatcher's dream of a property-owning democracy shrivels. And shrug our shoulders as home ownership reverts to what it was in the 19th century: a privilege, the exclusive preserve of people with large incomes or wealthy parents. Mr Boles will claim that the inflation in house prices in recent decades has been unacceptable and was caused by artificial restrictions on building. He will highlight figures showing that if the price of food had risen in line with housing over the past 30 years, a chicken would cost £47 and a jar of coffee £20. "In the 1990s, the average person setting aside five per cent of their income each week could save up a deposit on a house after eight years," he will say. Today it would take the same person 47 years. The planning minister will add that the public must accept that more building is required on greenfield sites, saying: "We've got plenty of undeveloped land to spare." He told this newspaper: "We need to build more, not all of it can be satisfied by empty homes and 'brownfield" sites, so we will need to build quite a lot on currently undeveloped land. He added: "I am not a critic of Nimbys. My job is to create a system that persuades them not to object but to get involved. We have comprehensively failed to persuade people to embrace the level of house building that is required. So the cost of building becomes completely unaffordable, so people build c--p. Under plans to be announced on Thursday, local people would keep up to 25 per cent of revenues from a Community Infrastructure Levy which builders pay to win planning permission to spend on community projects, such as a village hall. "Work out what you want, where you want it, what you want it to look like, the money that enables you to reopen the municipal pool," he Mr Boles said. He insisted that he understood opposition to development and had personal experience of fighting it: his father was the head of the National Trust. "I was a Nimby once, and my entire family were," he added. Last year, The Daily Telegraph led a campaign called Hands Off Our Land urging the Government not to weaken protections for greenfield land amid proposals to "simplify" the planning system. Ministers later agreed to a compromise.
