old window

I've had my eye on this window at work for a long time as it seems so different to most of the shiny new buildings. I needed a quick blip tonight as I left work late and am on call, so took this in the dark using a flash , then used an HDR filter (although its only one exposure). I'd like to take it again in the day and get someone inside to press their face or a hand against the window. There is a  handy chair   the other side of the window that I've blipped before which could be stood on if required as long as it isn't moved.
