Site Costs

Site Costs explained in detail

Additional costs required to prepare your block for construction. These can include site cut, fill, retaining walls, rock removal, soil treatment, service connections, and tree removal. Site costs vary dramatically between blocks and can range from relatively modest for a flat, serviced block through to very substantial amounts for challenging sites with slope, rock, or poor soil. In Adelaide, the biggest site cost factors are soil classification (reactive clay is common in parts of the northern and southern suburbs), slope, and existing trees. Site costs are almost always listed as a provisional sum in building contracts, which means the final amount can change. Getting an independent soil test before choosing your block or signing with a builder is a common way to reduce surprises.
