Why choose it? A pioneering building that showed what is possible. It was a nicer place to be than other supermarkets. It was refused listing and controversially demolished in 2016. The building raises lots of questions. Does it make sense to deny a building listing just because it is too young? Would it have been OK to demolish St Paul’s cathedral 15 years after its completion? Was there a lack of commitment from big business? Or does the fact that it’s now gone prove that it wasn’t a good building anyway? Whatever your view, the building moved the debate about sustainability on in this country and is still referred to.
