Best laid plans

Yesterday I was meant to take my Aunt to a Gallery and then we would visit Grays Antique market were I would um and arr about whether I should buy £15 costume earrings and then be sad I couldn't buy a Bakelite broach. Instead the dog became sick (trip to vet) and the adaptor gave up the ghost; so went to a Computer Fair, at a campus building(off Tottenham Court Road. My big day out!
And we saw this unusual and ugly building, this is the side view, the front looks like some perspex box.
