Another aspect of Australian suburbia is that the suburbs tend to have a combination of both upper middle class and middle class housing in the same neighbourhood. In Melbourne, for instance, one early observer noted that "a poor house stands side by side with a good house." This is somewhat less common today, with home renovations, gentrification and the teardown ("knock down, rebuild") method becoming more and more common in affluent suburbs, giving a broader distinction between wealthy and lower class areas. However, the teardown technique has led to home buyers purchasing land or older homes in poorer metropolitan areas and building extravagant homes on the land, which look out of place and excessive, failing to match with the remaining houses in the street.
