Building a home: What are the hidden costs?
Building a home can be an enticing option for many Australians, but there are plenty of unforeseen costs that can come into play. What comes included in a contract for one builder might be an optional extra for another, and there’s always the chance the overall price ends up several thousand dollars more than expected. Below are just a few things to keep in mind when drawing up your budget.
Soil and contour tests
Before building on a piece of land - in fact, before even planning to build - you’ll have to conduct a soil test. This will tell you how reactive the soil is (how likely it is to move, expand or contract with moisture), which you’ll need to know to determine how much weight it can support.
If it turns out the site you’re building on has sub-optimal soil - that is, it’s prone to above average levels of ground movement - a lot more work will need to be done to secure your home’s foundation, which will drive the overall cost up.
Another pre-build requirement is the contour test, which determines the slope of the land. Generally speaking, a sloping site is much harder to build on than a flat one (drop edge beams will be needed to prop up the floor slabs, and in some cases a specialist might need to be called in) so the cost will be greater.
Site preparation
Besides soil and contour tests, there are a few more costs involved in preparing the site for construction. These include connecting utilities (gas, water, electricity, and a sewer system), building retaining walls, and temporarily closing off roads if necessary. If you’re building in an area that’s prone to bushfires or flooding, this will also require more work.
Temporary site requirements
If you’ve walked past a house mid-build, chances are it was surrounded by temporary fencing and contained some combination of bins, portable toilets and other equipment. These will need to be hired by the building company, so make sure to ask if they’re included in the quote.
Modifications
To avoid paying more than you have to, try to stick to the plan as drawn up in your contract. While builders provide a reliable estimate of the cost of materials and labour required to build your home, any modifications made midway through construction will throw a spanner in the works.
The team at WA Country Builders recommend having a clear idea of how much you want to spend on upgrades from the get-go and discussing any changes you want to make with your builder before the construction phase.
“Before you sign up, and just at that pre-start stage, it’s very easy to make changes to a plan and it won’t cost a lot, unless you’re adding things in. If you’re taking things out, you’re getting money back,” they said.
“If you then get to a point where you start making these changes whilst you’re out on site, the builder will charge you for it because it’s disrupting the progress, and we’ll have to stop trades, we’ll have to order materials.”
It also pays to remember that some things are much easier to add later on than others. For example, cosmetic changes, such as replacing a bench top you’re not too happy with, are a lot easier to make than reconfiguring plumbing and electricity after they’ve already been installed.
Driveways and landscaping
It’s not uncommon for building contracts to exclude anything outside the building, which means you might need to organise to have the driveway poured and landscaping done once construction of your home is complete. Alternatively, you can hire specialists who can liaise with the builders throughout the construction process and commence work at a later date.
In the end, it’s in your best interests to chat with your builder and find out which services are included in the quoted price and which aren’t. If it turns out you’ll have to pay extra for certain features, find out the cost upfront so you can fit it into your budget.
