The new terminal mentioned is the building which graced the covers of the proposed masterplan for the airport, a glass-fronted structure which would have been constructed alongside the current terminal. MAG unfortunately were not able to provide the necessary funding to go ahead with this major building work, so instead the airport is making do best with what it has, by adding extensions all over the place (I count; the low-cost airline check-in hall, the new pier and the new shopping mall by arrivals) and a major overhaul of the existing facilities which has been ongoing for a while. The entrance to the security queue will start at the old Ilkeston Co-Op Travel shop (currently being used by the Aviation Hobby Shop but will become Securicor offices) though I believe the provisions are for these to house both the queue to the security checkpoint & central search, so queues shouldn't extend into the check-in hall.
