This 6,800 square foot Gold Coast duplex is one for the gajillionaires out there. Not only does it have every luxury amenity imaginable, this place takes it up a notch and even includes a 1,400 square foot terrace and a freakin' private dog run. This opulent pad has three large bedrooms, four bathrooms, a library, a custom spiraling staircase and five fireplaces. There's more than enough room for a pool table and its new owner's stacks of cash, which will be needed to cover the $6,500 monthly HOA dues and steep property taxes. For $7.9M, this ridiculously opulent pad could be all yours.
