Home site costs are something that stumps a lot of people who are in the process of building their own home due to unknown home site costs. This leads to under-budgeting and related issues. To avoid any of that from happening, it is important to understand the scope of site work. There are five variables to consider. Here is a detailed breakdown of expenses to expect.
1. Bushfire Attack Level (BAL) rating
In Australia, a bushy location or a site that is near a national park may have a Bushfire Attack Level rating. If the property you are building sits on a declared bushfire area, you need to upgrade the house to BAL-12.5 (the minimum level), which will incur additional costs. This is to make sure that your building has the necessary adjustments to make it as safe as possible.
If you want to know the BAL assessment charges, it depends on where you are planning to build, such as a treed area. You may also need a Bushfire Management Overlay (BMO), so check first with your builder if all of these apply to you. If you want to avoid this home site cost, finding land away from bushfire-prone areas is your next option.
2. Block Sloping
If you’re building on a flawlessly flat location, you don’t need to spend on this cost. However, if there are slopes in your property, extra charges may apply. This will depend on the results of the contour test to be conducted by a surveyor. Front-to-back and side-by-side slopes have different costs, so there is no standard estimate. There are also building companies who won’t be able to build on a site that has a slope of more than 3 metres, so you may need to consider getting a custom builder. This, of course, is another cost to consider.
3. Soil QualityHaving a surveyor conduct a soil test in your area will incur charges, depending on your location. The good news is, if the results show that you are building a new home on a soil that has an M-classification, it will help you save money. Otherwise, you will have to spend for extra costs if your builders will find it hard to construct your house due to a rocky surface or poor soil quality.
