This wonderful streamline Art Deco entrance belongs to a large block of flats in Worthing, in the south of England.
No doubt it once had a flagpole as can be seen in the entrance to the commercial part of the building around the corner.
I don't know what business originally occupied that part of the building but as you can see back in 2000 it was a Blockbuster Video store and as far as I know it still is.
The raw concrete and upper floors of the flats have been painted white since I was there as can be seen in Alan Cooper's 2006 photo on http://www.geograph.org.uk.
There would be a nice sense of irony if this had once been a cinema, now a Blockbuster Entertainment store but it looks more like a showroom with lots of glass on both floors.
