Very revealing. Four floors of retail, then ticket hall below that
and the platforms below that.

I was wondering why they needed such a long building if the trains
were below the surface. RETAIL!

Maybe they wouldn't be allowed to have platforms below water.

They are below water, just like the Jubilee line station.

The Jubilee Line station looks like it's entirely below ex-water to me.
