I once suggested this in jest

Yet Ireland will do it for real:

About 1,850 housing developments, unfinished after the bubble burst in 2008, pockmark the Irish landscape, according to government figures. This week, Ireland’s National Asset Management Agency, the state agency set up in 2009 to purge banks of their most toxic commercial property loans, started the destruction of an apartment block for the first time.

“There’ll be some places where the most sensible decision that can be made will be to demolish,” Housing Minister Jan O’Sullivan said in an interview in her Dublin office on July 10. “If nobody wants to live in them, then the most practical thing to do possibly will be to demolish what is there.”

In part it is a safety issue.
