On searching for the K8's, I came across this one....
A post office in a phone box. Who would have thought there would be room apart from Dr.Who
That's a thing of beauty, never seen one of those in the flesh before, the K1s with the perforated tops were the forerunners of the K2 and designed by the same architect but we're only put in London. We should start an "Architectural Curios" forum on here for people to post the weird stuff they find on their travels....
