Stansted Airport holding a Supplier Engagement Day next month as part of the approved Stansted Phase 2 development itself costing £300 to £400m.

Projected up to £230m to remodel the main existing terminal into a dedicated departure building.
With that costing for the already existing terminal that indicates some extensive re-modelling both landside & airside particularly bearing in mind that MAG also remodelled it with the original TTP after acquisition & in 3 stages over a couple of years 2014/16.
