Entire Floor Condo

Maybe this is more of a WIBNI idea and perhaps this has already been baked but I see a number of abandoned tower-type apartment buildings and office buildings that would make great mega-sized condos if each floor was converted into an entire unit. In many average sized towers, this would be 8000 to 9000 sq. feet of living space. Essentially you would have the space of a mini-mansion with all of the amenities of a condo. The parking outside could be re-divided into separate outdoor sections dedicated to each owner who has a floor in the building. This area would be where the owner can park the car, have outdoor activities, or even plant a garden. If there are typically 12 to 15 units per floor (depending on the size of the building), every owner could could have the equivalent of 20 parking spaces. That would be bigger than the back yards of many single famly homes.
