The $12.2 billion home is confirmed to be a fake. A number of sources around the web including reputed design blogs and business blogs(those of the likes of Wall Street Journal and Business Insider) are picking up syndicated feeds and reporting a false story to be true.

We are keeping the quote and the images just for chuckles. :) -------------------------------
