Brutal

The Shell Centre, South Bank, River Thames, London.

Undergoing refurbishment. It's pretty brutal but there are actually some lovely features – I'm waiting to see if they survive – including the layout of the public space around it.

The bronze window frames and Portland Stone cladding were apparently criticised when it was new, for being backward-looking. In fact, I think they've helped it age rather better than a lot of its (1961) contemporaries.
