We also have to remember that the plans in the planning application and the artist impressions can change dramatically before and after the work has started.
The terminals new stick out frontage did not appear in any applications I saw as can be seen in this original artist impression of the terminal. This one was the first of three.
The second version was still with us after the work started.
This is what we are getting. With the new terminal extension to the front the canopy ended up a lot smaller.
