You know what the problem is with a house of that magnitude? It has so many styles incorporated in it because of its size and abundance of rooms that are individually decorated without a central, classical and timeless theme such as colonial homes for example. Built in times where the interior architecture is still relevant to this day and attracts a certain large portion of the wealthy and upper middle class. Where as something like this needs to be constantly updated to meet that ever so rapidly changing decorative style.
But that's pretty much what it's all about nowadays anyway. Come up with a new and brilliant concept but market it in a way where it needs to be constantly updated with a particular & incremental time frame in mind.
That house is amazing, though, lol. Only $40 mill?
