I really think that the national pastime of Australians is renovating and the the holy grail is the house extension. We all have dreams of taking a small, pokey period property and blowing out the back to create an open plan inside/outside family relaxation and entertaining space that doubles our floor space and exponentially explodes our enjoyment of home life.
