Browse Forums Building A New House Re: Building - Fixed costs 5Dec 08, 2016 10:17 pm I'm an estimator for a Perth building company, working on a single storey 2 bathroom house as its easier there are a lot of costs that stays the same between a 100m2 house and a 300m2. Going from the start of the building process excluding shire fees I will do a brief rundown. Engineering and surveying fees are exactly the same, so is energy rating, indemnity insurance or how I think it's called in the eastern states is very similar in price, you would have exactly the same amount of deliveries for suppliers which doesn't seem like much but does add up. Plumbing is very similar as well, maybe $1000 difference between the 2, your main electrical items that cost the most stays the same as well, whitegoods don't change neither does waterproofing costs (this would probably be different on the east coast) the commission a sales rep makes is probably the same. The highest cost in WA is probably plumbing and commission to the sales rep which would be very similar to both houses, hope this helps Thank you so much everyone. This all makes a lot of sense. I guess when you talk to a builder who butters up everything to look very polished, you get to start believing… 7 17518 So AFAIk the outcomes of the BAL ratings form part of a clause that allows them to pass these costs on to you. However the more relevant detail is how did it go from 19… 1 9142 I am not sure whether Perth has its own way of doing things in regards to this. Most of Perth has class A (sandy soil), except for some areas near rivers or hills. 2 13063 |
