When it comes to building a home, not all blocks of land are created equal. Some sites present steep slopes, tricky soil conditions, limited access, or bushfire and flood zones – and these challenging sites can quickly become costly if not handled properly. At Prescom Constructions, we specialise in tackling the kinds of projects other builders might shy away from, so we’ve seen firsthand the common mistakes homeowners make when building on difficult blocks.
Here are 10 costly mistakes to avoid when building on a challenging site:
Many homeowners underestimate just how important a proper site assessment is. Soil type, slope, drainage, and accessibility all affect the design and cost of your build. Without this step, you risk unexpected problems (and budget blowouts) down the line.
Not every builder has experience working on steep or complex sites. Choosing a volume builder who’s not equipped for the job often leads to delays, costly variations, or designs that simply don’t work. You need a specialist builder who thrives on these challenges – like Prescom.
Challenging sites usually require advanced structural solutions – retaining walls, deep foundations, or piers. Cutting corners on engineering, or working with someone inexperienced, can compromise safety and cost you more later to fix.
Narrow streets, limited parking, or no crane access can blow out timelines and budgets. A well-planned approach to site logistics is critical to keep things running smoothly.
Steep or uneven land often causes water run-off problems. Without proper drainage solutions in place, you risk flooding, soil erosion, or even damage to your home.
Challenging sites are often located in sensitive areas. If your land is in a bushfire-prone or flood-affected zone, you’ll need extra compliance measures – and ignoring these upfront can cause approval delays and major cost increases.
Trying to force a “standard” home design onto a complex block rarely works. Your home should be tailored to the site’s unique conditions, maximising views, natural light, and stability.
Challenging builds often require specialist equipment and trades. Without a realistic budget (including contingencies), homeowners can find themselves halfway through the project and running out of funds.
Difficult sites often face stricter council approvals. Not engaging with your local council early can delay your project significantly. Working with an experienced builder who knows the process is invaluable.
Trying to cut costs by managing a complex build yourself is one of the biggest mistakes. Challenging sites demand expert coordination, compliance knowledge, and problem-solving – skills that come with experience.
At Prescom Constructions, we believe challenging sites shouldn’t mean giving up on your dream home. Our Avalon and Como projects are perfect examples of how smart design and expert construction can transform steep, difficult blocks into stunning, functional homes.
When you work with us, you’re choosing a builder who understands how to navigate the complexities, avoid costly mistakes, and deliver a home that’s tailored to your land – no matter how challenging.

Prime Costs (PC) and Provisional Sums (PS) are essential terms in construction quotes. Prime Costs cover allowances for materials like fixtures or appliances that haven't been selected yet, offering flexibility but potentially leading to additional costs if more expensive options are chosen. Provisional Sums are estimates for work not fully defined when quoting, like excavation or retaining walls, and may change due to unforeseen circumstances. Understanding the distinction helps homeowners manage budgets and avoid surprises during the building process.

A pre-handover inspection is crucial when taking possession of a new home to ensure any issues or defects are addressed before the final settlement. Key areas to check include the structural integrity (e.g., walls, floors), fittings and fixtures (e.g., taps, doors, windows), kitchen appliances, bathroom tiles and plumbing, electrical systems, and finishes like paintwork and flooring. By thoroughly inspecting these aspects, homeowners can prevent costly repairs later and ensure a smooth transition into their new home.
