"I know that worthy people are deeply concerned over governance proprieties in relation to this matter but...."
You skip over the deeply concerning issue of the lack of transparency and democracy in a multi-million pound publicly funded project like it is a field of daisies.
Taste aside. It is a privately managed space at the expense of the public purse that will be of little benefit of the public footing the bill.
The questioning is from a diverse body of people, not only the miserablist Heatherwick haters and RIBA hypocrits, but from those who are commonly known as "citizens".
I'm glad you don't like stooges and dictatorships and I'm happy to hear that you had such a fantastic business trip in Dubai.
