You’ve probably heard of the 56,000-square foot Spelling Manor that just sold to billionaire heiress Petra Ecclestone or the 43,000 square-foot Fair Field estate belonging to billionaire industrialist Ira Rennert. You may even be familiar with the palatial pads that some real estate developers have built in the hopes of finding wealthy buyers like Alpine, N.J.’s $68 million Stone Mansion or England’s Updown Court (which now faces foreclosure).
