corner of brock street and hampstead road., regent's place being reflected by offices opposite

That's it, SL. the reflection is in the offices on the corner of Hampstead Rd/Euston Rd. The yellow and blue on the left is that bird mural on the new flats by Sainsburys.

it was the bird that gave it away, gloss paint on sheets of aluminium by some turner prize type artist, the sort of nursery "art" that office building property developers use as meaninglessly bland fig leaves for their unspeakably boring buildings. or is it deeply ironic ? bet it cost a fortune. . . .
