<H5>Oxford Street North Side on the Corner of Hanway Place</H5>

What do you make of this Oxford Street building? I find it a jewel of restrained modernist design. It's No. 52, on the corner of Oxford Street and Hanway Place, and if you can throw any light on its architectural origins I'd be grateful. It's presently home to a perfectly nice Noodle Oodle on the ground floor.

The side elevation shows the design in more detail. The paint is relatively recent: the original surface is shiny black highly polished stone.
