    I am looking to build my first house for owner occupier and no knowledge of construction costs or how to go about it so appreciate some insights. There are 2 lots I am considering.

    1. Slightly sloping towards the back but 75k more expensive than #2.

    2. Sloping twice as much as #1 and the slope is to the front of the house, however the slope is still not drastic.

    Both lots are just 100m apart so not much impact in price due to location.

    My question is, should I go for #1 as the site costs are reduced because of gentle slope though I pay $75K higher in price (and known upfront) or should I go for #2 as the front slope could be used to make it garage at lower level and level out the back with additional soil? So spend less on the land purchase cost? Thanks.

    Have you chosen a builder yet?

    If so, ask them about the effect of the slope on what you can build and how much it will cost.

    This is a good idea - the variance is going to be very site specific so they'd be best placed to help. General rule is the less slope the better but it'll depend on all sorts of variables like stormwater etc.

    Thanks. Should I be identifying a builder before choosing a site? Also, it would take longer to shortlist a builder and the land may get sold while I am identifying a builder- how do you normally go about it?

    A separate question would be how do you go about identifying the right builder and check their prior work? For e.g., I was thinking of the big brand names like Rawson or Coral homes.

    If I were in your position I'd want to at least have an idea on what rough numbers a build is going to cost before committing to a purchase. Appreciate you're doing it for an owner occupier and not as a profit making exercise but it would still be prudent to make sure you're not over-committing yourself.

    You can ask the builder for a list of completed projects and WIP (some you may be able to inspect), as well as reviews and customer references. With those big guys you'd want to make sure you've got everything agreed in terms of finishes etc and minimize any variations.

    I've built on a few slopey blocks, some very slopey. Site costs really depends on a case by case basis but if you have a good design and engineering that works with the slopage, your site costs can be greatly reduced. I'd be very hesitant to pay extra 75k for lot 1 unless the slopage is a significant issue affecting SW etc. Best to get a builder or estimator to the site to give you cost ideas.

    Its another one of those how long is a piece of string question. There are so many factors that can affect the build cost, and the first question is what construction method are we talking about as that can significantly fluctuate the PPSM. Other things that can affect is slope degree which can significantly increase scaffolding and access/handling etc. SW issues as you pointed sloping to rear which may come with additional statutory costs and requirements etc.

    Are both lots the same size and shape? If so the 75k sounds like a fair hike in price, I would check the contract to make sure the cheaper site doesnt have easements/sewer/water mains running through the block.
