"Dwelling approvals data which was released by the ABS earlier this week shows that developers are beginning to look to develop a much greater number of units than they have historically. Throughout 2012, 90,144 detached houses were approved for construction and 61,042 units were approved. In comparison to the number of approvals throughout 2011, house approvals have fallen by -4.4% whereas unit approvals are up by 6%."
