Building on a sloping block - what you need to know

While some people look at a sloping block and think of it as a challenge, we think you have an exciting opportunity to create a unique home with great views, natural light and interesting architecture.

At Preston Building, we’ve worked on plenty of sloping blocks and understand how to make them work for you and your home. Here’s a guide we’ve put together to help you understand what it means to build on a sloping block and how to make the most of your site.

Firstly, what is a sloping block?

Quite simply, it’s a piece of land where the ground isn’t flat – it can slope up, or down across the site. There are different gradients, from gentle to steep, both having a significant impact on the design of your home.

While flat blocks are often easier to build on, sloping blocks offer unique advantages, like better drainage, more privacy, and the chance to take advantage of views and natural light.

Why sloping blocks need a different approach

The main difference when building on a slope is that you can’t just put your house down anywhere. The slope affects:

  • Foundation design: Your builder will often need to design a stepped foundation or use retaining walls to create level building areas.
  • Site access: Construction equipment, deliveries, and even getting in and out of the house might need special consideration.
  • Drainage: Water naturally flows downhill, so managing rainwater and preventing erosion is crucial.
  • Cut and fill: This means cutting into the slope or filling in parts to create flat areas, which can impact costs and timelines.

Key things to think about when building on a sloping block

Here are some important things to keep in mind when planning your build:

  1. Split levels

Instead of fighting the slope, good designers use it to their advantage. Split-level homes, where different parts of the house sit at different heights, can create interesting and practical living spaces. It also reduces the need for excessive earthworks.

  1. Views and natural light

Often, sloping blocks have better views than flat blocks. Designing with large windows, balconies, or decks that face downhill can open up your home and bring the outdoors inside. South or north-facing slopes also impact how much sunlight your home receives, which in turn affects both heating and cooling.

  1. Retaining walls

Retaining walls aren’t just practical; they can look great too. They hold back soil, help create flat outdoor spaces, and improve drainage. As your builder, we can advise on materials and styles that suit your block and design.

  1. Access

Getting in and out of a sloping block can be tricky. It’s important to plan driveways and parking areas carefully, considering slope gradients and safety.

  1. Drainage and Waterproofing

It’s important to ensure your home stays dry, so you’ll need good drainage systems, waterproof membranes, and careful landscaping. If you ignore these things, it can lead to expensive repairs later.

The benefits of building on a sloping block

  • Better views: You can design your new home to capture the incredible view.
  • Privacy: A sloped site can give your home a more private feel.
  • Natural ventilation: Elevation can help with airflow and cooling.
  • Unique architecture: You can get creative with your home design.
