pier 7
I just searched google for pier 7 Gatwick and there's a bit of info about a new pier possibly being built where cargo is / was. Apparently it's a low cost pier accomodating 4 A380's. Low cost certainly doesn't even come close to £1BN, even with a new pier 1 and all the other work they're doing. Maybe lot's more colourful bus lanes and a car park might do it.
