Ok just spoke to Saffron and here is the latest:
I have asked for more info with regards to the Developer but this is their first build so not much maybe available.
Planning permission is only verbal, nothing in writing.
They are getting back to me with regards to if the contract can be amended and certain words can be changed etc.. like "envisaging".
They are also getting back to me to see if they can issue me with something in black & white that states if the development does go "pear shaped" then we would get a full refund of monies so far paid without penalty.
Saffron are being very good about this i must say have i have no reason to doubt them at all, i would sign if the contract today was with them, but its not.
Must admit i am now even more uneasy i think oh the whole as its this developers first build..
