This was a really interesting project. Not only did we need to show a pair of buildings being constructed over time, but we also had to demonstrate that the adjacent railway station would be unaffected during the construction phase.
Because there was so much informaton to convey, at 16 seconds we switched to a split screen to allow viewers to see the scheme from two different perspectives simultaneously.
You may notice that the Pixel Express runs to schedule throughout, possibly helped by the fact that it never stops to pick up any passengers! The eagle eyed among you may spot the people arriving on foot at the station!
