Well looks like I will join your race too! If you dont mind.
We have been advised of site start 16th November dependent on weather and slab on 25th November also dependent on weather.
Our house is 1 story so it might not take that long-but i am thinking they will finish around mid April. I have started a blog so if you want to can check on the progress on there - http://hordefamilyhome.blogspot.com/
Good luck all keep posting updates
