I had this with put into my PPOR build contract, however most builders will tally up any and all excuses. My 2-storey PPOR was a 24 week build period and they scraped in at 23.57 weeks. They still had rain days and non-working days up their sleeve ( Xmas period ).
Just out of interest, what contract period did you sign them up to - just wondering how long a build like this takes from the construction certificate being issued.
38 weeks. I have another development which they will most likely get so I want to build a relationship where I pitch em' and they smash em'.
