Hi, I am looking to build a duplex in Sydney and keen to get everyone's feedback on the below quote I got from a custom builder. Few things to note about the duplex - 5 bedroom, 3 bathroom, - Total land 700m2 so 350m2 per duplex - Internal area maximised per council regulation - Builder margin quoted 15% which i believe is quite standard around my area - Full design and engineering report to be completed and the below has been quoted based on DA approved plans which doesn't have exact measurements. - I have been advised to proceed with the design and CC application and engineer design totalling $12k to firm up the below quote. Sorry for the poor format. I am building this based on high end finish with the aim for selling one side and living in the other. Keen to get a view if anything stands out as ridiculous or understated?

I can't speak to each line item but based on the total and the size you are assuming it will cost around $1600 per sqm which I don't believe would get you high end finishes in Sydney but your idea of high end and mine may differ 2 line items seem a bit skinny 1. lighting - I assume this is feature lights and all downlights and exterior lights. I can spend $500 just on my island bench light so this needs to be increased a lot 2. bathroom PC items - I'm assuming this is toilets, baths, tapware and as each house has 3 bathrooms the $5000 is not going to go far
