So exciting! We did our house twice - when we first bought it in 2009, we renovated only (didn't extend). And in late 2011/early 2012, we extended it to go from a single storey 2 bedroom place to a 2 storey, 4 bed and 2 car garage place. The only advice I have is to not get handleless cabinetry because it's a freaking pain in the ass. And if you are carpeting, invest in a great vacuum and a carpet cleaner.
