One step away from Godwin's Law.... here comes the comment about H*tler....
There is nothing right with that block..did you ever visit the WCCP next door with concrete peeling the girders and more leak than roof?? God help us if we need to protect this lump there is nothing special or modern about it, next will be Burlington House listed
I beleive Brook House was riddled with dry rot, sinking in the river bed and beyond help.
