I asked about this at the Colour selection/kitchen appointment and was told to talk to SS during construction...probably another thing Ill just fix later as I do prefer having the rangehood ducted outside and not just into the roof cavity.
Good news for us, I have finally received actual communication from our SS and he has confirmed excavation will be either today or tomorrow. The start was held up due to civil works that had to be completed under the footpath in front of our block which was completed on Christmas eve.
We do have an issue with Window supply so the roof will go on before the bricks. Hopefully that will be finished by End of Jan then windows and bricks first week of Feb.
Just need this rain to hold off and not get heavier.
