I think there are a couple of issues. One is a laudable desire to
provide some nicely designed "different" buildings

Why is this laudable

This is meant to be a convenient transpoprt interchange, not a Tracy Emin-style
work of art.

This is fine
provided you don't spend huge sums achieving it

Yes, the fare-payers' and tax payers' money!

As usual, all form and no substance - but in this case eventhe form is
doubtful!
