There are other applications to use the lower parts for retail purposes
but those lower areas are BRB residuary's responsibility, rather than
Network Rail.

This has led to previous media articles suggesting that whole
international 'station' would be turned over to retail, which TTBOMK
has never been a possibility...

If you demolished the check-in gates and security area (I expect they've
been robbed of all their equipment by now) you'd have quite a big area,
and extending into the original departure lounge if you wanted to.
What's going on "upstairs wouldn't be relevant.
