In 1984 according to the Bureau the average new NSW house was around 159 per square metres, giving each of the people in it around 60 square metres of personal space.

It may also be an international record.
The latest US figures show the size of new American homes sliding... shrinking from 212 square metres before the financial crisis to 202 square metres in September.

The figures lend weight to concerns expressed by senior Reserve Bank officials that we are investing in houses rather than housing.
Deputy Governor Ric Battellino told a Melbourne conference in November that almost half of the $250 billion spent on housing each year went on alterations and additions with 1 in every 7 new houses "simply replacing existing houses that have been demolished."
Governor Glenn Stevens spoke on the Seven Sunrise program this week about the importance of increasing the stock of houses rather than increasing their value saying his children "within not too many more years are going to want somewhere of their own to live."
He has told a business audience he would regard what happened to house prices as a measure of his success saying "if all we end up with is higher prices and not many more dwellings then it will be very disappointing, indeed quite disturbing."
The ABS finds new new Tasmanian houses the smallest in Australia at 196 square metres, and notes that in recent years they have been getting smaller.
