At first glance it is a bit ostentatious, having your Maserati in your living room and a car elevator to get it there, but in some ways it makes sense. Underground parking is expensive to build and inefficient, with about 125 square feet of circulation and ramping for every 200 square feet of parking. With a car elevator there is no extra floor space at all, just the area of the elevator shaft and the extra wall enclosing it.
The developer explains to Reuters that these apartments are for those who have been around the block a few times.
"These buyers are very discerning, they have seen a lot. They are well exposed in the world, so they are looking for something that is unique and different."
I wonder if it couldn't have been more efficient; with only two units per floor, could they not have put the car elevator in between the two. Even so, it would be interesting to see the numbers on this, whether it is actually more expensive to build this way than it is to go down and have ramps. Less concrete, less excavation, one might even call it green.
