IRT KL Walter:  I agree with the part of your comment stating that single family urban sprawl cannot go on.  It may be the ultimate dream to own a single family home like your parents or grandparents have/had, but we need to understand that land on an island is obviously finite.  We cannot continue to build large single family subdivisions.  I know that sounds like we are headed for a Hong Kong like scenario, but unless we somehow curb population growth, we have to try to fit more people per square mile because we WILL run out of land at some point, and once single family homes are built, they generally aren't torn down to make way for high rises.
