^^^ i agree, if the market can't sustain the per sqf cost it doesn't make sense to build the building at all, not to say well 450 ft is profitable but 500 ft isn't. Generally once projects get started and theres no turning back they want to go higher because it is more profitable to have more units if they have already determined a market exists for the product, even if they might take longer to sell. I agree with the posters above that the sole reason for the building heights not being increased is the imposed height limit, and if that weren't in existance some of these projects would certainly be higher
