Both in Saltaire. And I can't decide which is the more attractive... the link with the past or the sight of nature asserting itself. I think I'm right in saying that the sliding metal plate is a coal-hole, through which they used to deliver coal into the coal-shed in the terraced property's back yard. As for the ferns, I remember being entranced as a youngster, learning about the mysterious life cycle of a fern. Often overlooked, I find them really pleasing plants, especially contrasted with the rough stone as they are here.
