Building on a sloping block

Building a new home or an extension already involves big costs, but these costs can go much higher if you plan to build on a sloping block. Calculating just how much more that will be is essential to knowing if the added costs will be worth it. There are lots of factors involved, and much depends on the individual block and its position.

Why does building on a sloping block cost more?

A number of reasons can explain why building costs for sloping blocks are higher. For one, steep sloping blocks can make access to the site more difficult which means extra expenses to transport the materials. Also, challenging engineering issues are common on sloping blocks. You may need to hire a structural engineer to help with both design and construction of the home, and you may also need a detailed land survey. Most sloping blocks need some excavation work done before the building starts, so that’s another specific contractor added to your expenses. The surface might have to be levelled, so expect to pay for extra foundation work as well. Lastly, there are also extra problems involved in landscaping a sloping block, such as retaining walls, drainage and erosion issues.

Are the added costs worth it?

There are certainly some advantages to building on a sloping block that can outweigh the extra costs. An amazing view usually makes it worth it. Natural ventilation is another plus for an elevated home built on a sloping block. Eco-designed homes situated appropriately can take advantage of prevailing breezes and offer a cost-effective alternative to air conditioning.

A further advantage is maximising investment returns. Homes on sloping blocks may cost more to build, but there’s a limited supply and high demand. People who make an income through professional home renovation often actively seek out homes on sloping blocks as they often fetch a good price when sold.

Any other useful information?

Quality design and construction are essential for successfully building on a sloping block. A high-quality, appropriate design can ensure a stylish home that not only has an amazing view, but can be a notable feature of the landscape and command a higher price from potential buyers. High-quality construction is also crucial to address the challenges of building on sloping blocks effectively.

Aim to get a builder who has solid experience in construction on a sloping building site. These builders will be more aware of potential problems expected on such projects and are likely to already have contacts with the relevant professionals and tradespeople needed, such as land surveyors, engineers and excavators. Their experience could minimise problems, delays, and costs.
