The MASSIVE SHED outside the LHR CH

Just heading out of the LHR CH (lovely as ever: big fan of the new roast padrón peppers) for the VS1.

Does anyone have any further info on the massive 'shed' which now blocks out so much of the view from the CH?

I've had different explanations from various CH staff: transit lounge; offices; temporary; permanent...

Any ideas?

I've also heard it's some kind of temporary transfer centre-type thing.

It's a 'temporary' T3 flight connections building.

Will be there for a while, but it is designed to be dismantled.
