Not sure if the plans are in the public domain but work has started today from 212 onwards, which will eventually see a large boarding lounge constructed at 212 for stand 213, 214 and 215 with covered walkways leading to them.
I've seen the plans, and it does look slightly chaotic but I'm sure MAG have thought it all through
