How Do You Know If a Block of Land Is Worth Building On
When you’re looking at blocks of land, it’s easy to get caught up in the price, the view, or the location. But not every block is a smart choice when it comes to building. Before you sign anything, it’s crucial to understand whether the land you’re eyeing is actually suitable for a new build, both practically and financially.
Check the Land’s Zoning and Restrictions
Every block is subject to zoning laws set by the local council. These determine what you can and can’t do on the land.
- Residential zoning: This is what you want for a typical home build.
- R-Code regulations: These affect setbacks, height limits, density, and more.
- Building covenants or estate guidelines: Some new estates have specific design requirements.
If the land has restrictions that don’t match your building goals, it may not be worth it.
Understand the Slope and Soil Type
A block that looks perfect on paper could come with unexpected building challenges.
- Sloping land often requires retaining walls or split-level designs, which can increase costs.
- Soil classification affects the type of foundations needed. For example, highly reactive clay soils can require more expensive footing systems.
Look at Access and Services
You’ll want to confirm what infrastructure is available or needs to be installed:
- Power, water, sewerage, NBN, gas
- Road access for construction vehicles
- Easements that might affect where you can build
If key services aren’t already connected, this can add thousands to your build budget.
Check for Bushfire or Flood Risk
In parts of WA, land may sit in a Bushfire Attack Level (BAL) zone or flood-prone area, which can affect your build cost and design.
- Higher BAL ratings may require fire-resistant materials and sprinklers.
- Flood overlays might limit house positioning or require raised foundations.
Get a Contour and Feature Survey
This detailed survey shows the land’s slope, trees, boundaries, and any features like existing fences or manholes. It helps your builder design a home that suits the block’s natural conditions.
Review Title and Encumbrances
A land title might reveal:
- Easements (for powerlines, drainage, etc.)
- Caveats or mortgages on the land
- Covenants that restrict design or usage
These legal details can significantly impact your future build.
Compare Similar Sales in the Area
Make sure you’re not overpaying. Even if a block looks great, it needs to be priced in line with the local market.
Speak to a Builder Before You Buy
Many buyers make the mistake of buying land before speaking to a builder. This can lead to surprises, like realising your dream home won’t fit or requires expensive modifications.
A cheap block isn’t always a good deal, and an expensive one isn’t always overpriced. It all comes down to whether the land can support the home you want, within your budget.
Before making a purchase, take the time to assess every aspect of the block, from the soil to the services, from the legal paperwork to the slope. And most importantly, talk to an experienced builder who understands Perth conditions.
