Building Your Wanaka Home on a Sloping Section

by | Jun 1, 2021

Building your dream home on a sloping section has its own challenges and it may even appear daunting, especially for first time home builders in Wanaka. However, it will be well worth the effort if your building company can utilise the sloping nature of the terrain to its advantage.

Challenges of Building on a Sloping Section in Wanaka

The main problems you face building on a sloping section in Wanaka, are the additional costs and the longer construction time. Building on sloped land requires complex foundation systems which could increase construction costs by as much as 50% of what is required to build on flat land. More concrete is required, and special excavation equipment will be necessary to dig deeper. The septic and drainage systems will need more complex solutions. The use of additional materials and labour will result in higher costs and longer lead times to complete the project.

Overcoming These Challenges

Fortunately, it is possible to overcome these challenges with the cut and fill method. This involves removing soil from the slope (cutting) or bringing in additional soil to fill the land (filling) in order to level out the ground for the foundation.

Benefits of Building on a Sloping Section

Building on sloped land provides an opportunity to have a breath-taking view of the surrounding landscape here in Central Otago. For some, this is the main attraction. It is often possible to carve out extra basement space which can serve as an additional floor. If you enjoy living in a secluded area where you can have some privacy, building on a sloping section is worth considering.

Factors to Consider

There are two things you need to consider when building on a sloping section.

1. The first is the gradient of the slope. The gradient rating is the percentage inclination of the land to flat surface. If the land is less than 10% inclined, building on it is less likely to present many problems during construction, but it becomes increasingly problematic as the gradient rating goes higher. Construction costs increase significantly above 15% rating because the work becomes more difficult and riskier.

2. The second consideration is whether the land is sloping upwards or downwards. Generally, an upslope land is more challenging to build on because it usually requires more amount of cutting. Transporting debris and soil to a safe disposal point will also be challenging.
