What planet have you been on, this was one of Steves babies.
It was Steve's idea. In actual fact he wanted to spend MORE on different flooring structure. Tim veto'd it otherwise it would have been billions more (and no I'm not exaggerating).
Either way, the actual design was done by Fosters, the same people who built the MTC: http://en.wikipedia.org/wiki/McLaren_Technology_Centre

That's where the design idea started out.
Correct me if I'm wrong, but didn't Steve pitch this entire idea?
Not sure if joking or serious. . .
Steve I think wanted more money spent on this and some of it was scaled back.
You are wrong.
