I mean the common podium design with a garage at the bottom works well and the space is not desirable in condo design. Larger high rises are the same as higher is more sought. Your not really losing housing as the parking is cheaper than fully done residentail for the square feet and taking much less square feet overall. I know a 3 over one that gives two spaces so a 6 over one should be able to do one easy enough and since lower sizes should be able to get the same out of even four flats as it just needs one additional story.
