For years we looked at the crazy modernist building at the end of our street and said "What a fucking dump!" (It's not exactly Nikolaus Pevsner, I know.) It was either sheltered accomodation or an athletes village for a joint East German/British Olympic bid in 1972. A few people lived in the crazy modernist building – walking past at night you'd hear crackly garage radio blaring out from an open window, or shouting coming from another window. But nobody ever went in or out.    A few weeks ago the crazy modernist building began gushing water like an incontinent cow. Then a wooden wall was put up around it, which usually means demolition time. I asked a hard-hat bloke what was going up in its place.    "Dunno mate. I only started today."    So, looks like there will soon be a crazy free improvised building at the end of our street.
