Just read about this one today…

I guess my main point in mentioning it was that the author of the TimesOnline stated, “A flat in central London has become the most expensive HOME in the world, with a price understood to exceed £115m.” With that said, it really depends on how one defines “home.”

and thanks making the edit clarifying the largest occupied…

There could be a large post on the topic of expensive or large single family homes, similar to other “World’s Most…” posts featuring numerous locations. I certainly don’t have the time though

@nova72 - In the article you linked to it states that the £115m building that was sold “is to be carved out of a seven-storey 1930s office block, which will be used to create a total of six extravagant apartments.” - so I’m afraid it doesn’t count, as we’re talking about 1 single home.

Here’s a forbes.com article about the world’s most expensive homes in 2007, which puts the most expensive sale at $165 million dollars.

(Giving me justification to stand by my statement that Fairfield is “estimated to be the world’s most expensive home.”)

However this is the crux of the matter - although it has been repeatedly claimed to be the world’s most expensive home, nobody could be sure unless Mr Rennert actually chose to sell it, which I don’t suppose he has any plans to.

As for largest and most expensive private homes: My guess is they’ll all be dwarfed by Buckingham Palace … which is technically the monarch’s property. It has a whopping 77,000 square metres floor-space and who knows what possible value. Of course it’s hardly likely to come onto the market any time soon
