What now for the former HQ? The building is T shaped so is bigger than it first looks with what looks like a flight simulator building attached at the bottom of the T.
Easyjet converted one of H89 aircraft bays for more office accommodation a few years back so I doubt that Monarch’s HQ is big enough for them.
Seeing that Flight Safety Boeing’s former European HQ was turned into a hotel this would be a much easier project if this building met the same feat.
