Striking stairs

Down the stone steps, past the bus stop to nowhere, before idyllic peace is shattered by traffic – heralded by passing through a gloomy passage in an unprepossessing block of flats – there are two striking staircases that I'd like to know more about. They are both, I believe, fire escapes for the St Peter's House flats. And while the flats themselves are nothing special to look at, I love the clean lines, bold design and chunky proportions of the stairs. Here's a picture taken on my phone, and a link to a rather better, dramatic photo by Derek Rigg.
