I finally plucked up the courage to ask if I could take photos in this building. It wasn't easy as I had to speak to four different people. When I approached the security guard to ask if I could taken photos, he initially said yes, but then I told him I wasn't using my iPhone but my big camera so he called his head of security who came down to see me. The head of security then asked the man at the staff barriers if it was okay, then the man at the staff barriers said to ask the lady at reception and so I went with the head of security to ask the lady at reception and she said...no problem. Phew. Thought I'd have to walk out with my tail between my legs. It was definitely worth the wait. This building is so cool.
