I’m looking forward to our exhibition Futures Found: The Real and Imagined Cityscapes of Post-War Britain which opens at the RA on Saturday. Meanwhile, I have been enjoying the book Lost Futures which accompanies it. It’s written by Owen Hopkins, formerly of the RA, now of the Soane Museum, about post-war buildings which have been demolished. I can’t mourn the loss of the Freemasons Estate in Newham which contained Ronan Point, where a small explosion in the kitchen of a cake decorator led to a collapse in the side of the building and loss of life (but not of the cake decorator, who survived). Nor do I miss the Stifford Estate, which occupied the site of Stepney Green Park, now being excavated for Crossrail. The big losses look to be Robin Hood Gardens, still there, but only just, due apparently to be demolished at the end of this month; and Gillespie, Kidd & Coia’s Seminary at Cardross which is now due to be preserved as a dramatic ruin, like The Grange.
