Back of a fag packet....
There is a quarter acre plot nearby that has outline planning permission and
is up for sale for a million - whether it will realise that amount remains to be seen, but it has a lot less baggage than the Kasssm.
The
whole plot sold to Kassam was 10 acres, but a fair bit of that is now taken up with hotels and the Ozone (with associated car parking), so there may only be 5-6 acres available for development and there would be considerable legal obstacles to overcome before any planning was granted.
On that basis, I think Kassam would be lucky to get £25m for the site and with Grenoble Road now a free hit for the likes of Taylor Wimpey, he's probably lost a bit off the top of that .....
