I'm not an architect, or familiar with construction practices, etc. My theory is however that because the demand for high end, luxury rental apartments, or even just apartments in general, is so high in some places right now that contractors/investors know that despite short-cuts and things like sound insulation, they know they can still fill the complex and meet/beat their ROI goals. The problem with that, I believe, is the demand will come and go and these buildings 10-20 years from now might have a hard time keeping the needed occupancy rate. So many things can affect that, i.e., young couples/families actually may not mind living in urban apartments, however; If a large number of complexes are terrible with noise pollution, they may opt to move to a stand alone house in the suburbs. And many other societal trends, etc. I think we are cutting corners on many new buildings right now that may create low occupancy areas later on. All the growth and development of today will be for nothing. It's the mentality of, "I don't care about this neighborhood or what it will be like in 10 years+, I can make my money now and move on, who cares". How do we make the large capital investment world care and stay interested long-term (10+ years).
