Most of the bigger builders' contracts are not fixed priced. Meaning that the build contract price will most likely be added onto during the build, due to extra site costs and extra Basix or Council requirements that are not covered in the contract.
A common example is rock, alot of blocks have rock that needs to be removed when the builder is cutting the block. The builder needs to dig it out, which is costly and time consuming, the rock has to be loaded onto trucks and the rock needs to be disposed of. Most of the big builders have a rock clause in their contracts stating that they are not responsible for this cost , this can mean an extra bill of around $20,000....and remember it is not only when they are digging for the slab that they can strike rock, but also when the plumber is digging to connect the drainage that they can encounter this problem.
Another example is fill, either the import or export of soil is needed to level the land for your slab. This is another clause in bigger builder contracts that can cost up to $3,000 extra
A further example is piering, the majority of builders will set the amount of piering allowance. Piering is drilling down to solid ground so the slab can be stabilised. The majority of times the piering allowance is not enough and it is not uncommon to see a bill for $1000 extra.
In regards to Turn-key-it means that the builder provides everything inside and out, the client does not need to organise any trades to pour the driveway ,or put up a retaining wall, it is all completed.
Again most of the big builders do not provide this service, at the end of the build the client is left with a lovely house but they have to move a big pile of dirt from the front yard and have sheets at the window because the builder did not provide blinds.
The price of Landscaping without retaining and a driveway is around $20,000 and retaining walls could be anywhere from $3000-$5000 depending on what is needed. A big cost if your block has over 1 metre of slope.
Just ask the question when you receive the build quote from the big builder who is offering a huge discount, what isn't included in the build price?...and if you have an extras bill of around $50,000 at the end of the build ,how will you pay for that? Are you on a strict budget?
You may be surprised at how affordable a fixed priced and turn-key builder is, they may not have the gorgeous display homes to look through but their pricing is honest and genuine with no hidden surprises..it's worth thinking about!
