Scourge of the Suburbs: Knock down and Rebuild

Goodbye houses with character and a decent front and back garden in the suburbs. Hello McMansions.

In Australia the average family size in 1966 was 3.5 people, now it's around 2.4. How come houses are getting bigger? Now people MUST have at least 4 bedrooms, home theatre/rumpus room, study, an outdoor room (because there's only a pocket handkerchief sized backyard) and a butler's pantry/second kitchen for Christ sake. More to heat, cool, clean and maintain. What will these McMansions look like in 50 years' time? 

Us working class baby-boomers lived in the family 3 bedroom house - all crowded around the black and white telly in the lounge ("the good room").

Established trees are chopped down. With no space for an established garden, our suburbs are becoming soulless, no longer homes for native wildlife and hotter in summer. 

New owners are either time-poor (too busy paying off the mortgage to devote time to gardening) or have no desire to keep up a garden.
