The Dog House?

This is on the old Abbey National headquarters on Baker Street in London. I guess linking the notion of security to banking these days would be to invite raised eyebrows!
A few years ago the building behind the facade was demolished & converted to flats, which involved supporting the splendid art deco clocktower on girders high above the street as the building rose up again to meet it. Sadly I wasn't blipping then...
Baker Street's most famous resident was, of course, Sherlock Holmes. Fittingly, the flats are owned by Baskerville Estates!
