I have a theory. Call it rubbish if you like, I don't particularly care.
The demographics of the area are changing. It's becoming more gentrified and house prices have rocketed. There has also been a recession so demand for state education has increased as fewer could afford to go private.
However, the economy is improving. Newcomers to the area are those that afford 500k+ for a family home. They need a sizeable deposit and salary.
Families who can afford to invest a million pounds to buy a semi-detached home in suburbia can also afford to invest in their children's education.
So whilst short-term demand for state secondary education has increased due to the recession, long-term demand may decrease as these new families arrive.
Perhaps LBRUT realise this and are planning to put the school in Heathfield to meet this long-term demand. I'm talking decades not just the next few years.
Perhaps LBRUT got together with Turing House and agreed a 50:50 split a year ago when they knew about the permanent site. The Council may have offered this site on the condition that the admissions policy is changed. Maybe then they propose a consultation to make it look like a democratic process and not to upset certain characters.
If millions are spent building a school, then no-one wants that money invested foolishly by building it in a location that suits short-term needs only. How long does a school building last? 50, 100, 200 years - more?
What happens if, in two years time, new councillors are elected, get-together and decide to sell the golf-course land in Fulwell. Who will buy it? This new government task-force? Doubt it as the school won't be needed then.
I definitely think like muminLondon2 that proposals for free schools should be put forward only once a site has been secured. It is nothing but chaos otherwise.
