Well, I can't say I'd be put off if they did fill them with flats. I take the bus up that way home from work, and I'm amazed at the sheer amount of unused space there is so central to London. What with all the complaints of housing crisis, they could house at least 10,000 people there I'd think, there's acres and acres of it! And once the rail link is complete all those temporary offices can be scrapped, as well, leaving even more room.
I'd agree with this. The scale of the derelict land and buildings around there is astonishing.

if people like you ruled we would have any internal and external public amenity space!
