Avoiding Unexpected Site Costs: Understanding the True Cost of Preparing Your Block of Land
If you're building a new home in Australia, you'll want to avoid any unexpected site costs that can blow your budget. Understanding what site costs are and how they're determined can help you prepare for the actual costs of building on your block of land. Here's what you need to know:
Soil Type Matters
The type of soil on your block of land determines the level of engineering required for your home's slab. Slabs aren't just a slab of concrete; they're highly engineered to ensure they suit the environment in which they'll be situated. Factors like rock, clay, sand, and soil content can influence ground movement, which impacts the necessary type of slab and the associated site costs. To ensure accurate estimates from builders, get your land's soil type tested by a surveyor before any quoting. This guarantees that you obtain a quote that doesn't underquote you for site costs and avoids disappointment later when the final cost may be significantly higher.
Soil Classes Help Determine Footing And Slab Design
Australia categorizes soil classes that range from non-reactive to highly reactive. Generally:
Class A soils (rock and sand sites) require the least amount of engineering.
Class S and Class M soils require low-to-moderate engineering.
Class H1 and Class H2 soils are clay-based and require high-to-very high engineering.
Class E soils need extreme engineering.
Class P soils are complex and can include fills like clay, silts, or loose sands, among others, and require a site-specific solution.
Consider Site Preparation Costs
Some of the site preparation work may have been completed before your block of land is offered for sale. Excavation costs can be high, so it's important to have the right advice early. Sometimes, developers may contribute or include site leveling costs in the purchase price. If site costs represent a significant hurdle for you, negotiate with the developer, or turn to a land buyer's advocate to do it on your behalf. Understanding these site costs will help you better prepare for the actual cost of building on your block of land. With careful planning, you can avoid unexpected expenses and create the home of your dreams.
