Mini blue door in a big blue door

More in the lunch time exploration of Thomas Melco building... As I was opening yesterdays blue door I heard a door behind me and scurried off ... whilst I scurried I came across this blue door that looks like it has a mini blue door in it...

I am enjoying exploring and each lunch time I go a little further in, it is tricky as it is open during the day and people are working, I've just never seen people, only heard them.

The window is red and I love the contrast between the colours but the black and white really gives it the old industrial building feel...
