My SS said that the work would be able to complete in 3 weeks time hence we was ok with the scheduled date for the PCI..
I will fix the independent inspection prior to that as I can forward the defect list to my SS at the PCI.
Regarding the underlay, I have upgraded to Cat 4 & it costs me approximately $730.
This is excluding the tile areas in a 35 sqm house
I would love to see pics of your build. The Wembley is a lovely house. I was thinking of building it but ended up going for the Waldorf.
