Since my last update, we have completed our electrical plan, signed off on the kitchen, laundry and bathroom plans and also added and finalised a bunch of "extras" we originally decided against during the tender stage. :-)
We also discovered that we actually have a window in our kitchen behind the stove. This was pointed out to us by the kitchen people when I questioned why the glass splashback didn't go across the whole wall - duh! This was a Basix/Council requirement so we didn't really have a choice in the matter anyway). It's right there in the plans but we never noticed it!
The Construction Certificate was also issued a few days ago so we are almost ready to start!
On a sour note, as we are one the last to build in our estate, our block of land has become somewhat of a storage facility and rubbish tip for all the other builders around. We even have a nice set of tyre tracks from a cement truck which went up the curb a few days ago and then dump its leftover concrete on our land.
