Choosing the right block of land is one of the most important steps in building your dream home or investment property. At SMG Construction, we know from experience that the block you choose can have a major impact on the design, cost, and overall success of your construction project. Whether you’re a first-time buyer or a seasoned investor, this guide will walk you through the key factors to consider when buying a block in Perth or anywhere in Australia.

1. Location, Location, Location

The old real estate saying still rings true: location is everything. When looking for a block, think beyond the present and consider long-term livability and value. Ask yourself:

  • Is the land close to schools, shops, public transport, and medical facilities?
  • What is the future development potential in the area?
  • Is the neighbourhood family-friendly or more suited to retirees or professionals?
  • Are there parks or green spaces nearby?

A well-located block will not only support your lifestyle needs but also improve the resale value of your property in the future.

2. Block Orientation and Sunlight

In Australia’s climate, the orientation of your block plays a big role in energy efficiency and comfort. A north-facing backyard is generally considered ideal because it allows your home to receive plenty of natural sunlight during the day. This can reduce heating costs in winter and make outdoor areas more enjoyable year-round.

Take note of where the sun rises and sets on the block, and how shadows from surrounding buildings, trees, or slopes might affect your home design. These are important tips for finding a perfect block that will support both comfort and functionality.

3. Land Size and Shape

Not all land is created equal. The size and shape of a block will influence your floor plan options, backyard size, and even how close you can build to the boundary lines.

  • A wider frontage can allow for a grander facade or side access.
  • A narrow block may require a two-storey design.
  • Sloping blocks might offer great views, but they also come with higher construction and excavation costs.

If you’re unsure how to choose the right block, consult a land or building professional early in the process to ensure your dream home fits your desired footprint.

4. Soil Quality and Site Conditions

One of the most overlooked – yet crucial – aspects of buying a block is the soil classification and overall site condition. Soil testing (also known as a geotechnical survey) will determine the soil type – such as Class A, S, M, or H – which affects how your foundation will be built.

Poor soil conditions or reactive clay can lead to higher foundation costs, so it’s best to know upfront what you’re dealing with. Also, check for:

  • Rock or fill materials
  • Flood zones or water drainage issues
  • Bushfire risk zones (BAL ratings)
  • Easements or restrictions

These site factors can have significant cost implications down the line.

5. Council Regulations and Zoning

Before you commit to a purchase, make sure the block is zoned appropriately for your intended use. Zoning regulations vary by council and can dictate:

  • The type of dwelling allowed (single, duplex, granny flat)
  • Maximum building height and setback distances
  • Heritage or environmental overlays
  • Easements and right-of-way access

This is one of the most important things to consider before buying a block. We recommend reviewing the Local Environmental Plan (LEP) or consulting your local council or builder, like SMG Construction, before proceeding.

6. Access to Services and Infrastructure

A block may look like a great deal on paper, but if it lacks access to essential services, you could be in for some unexpected costs. Always confirm:

  • Is the land connected to water, electricity, gas, and NBN?
  • Are sewer and stormwater systems in place?
  • What’s the condition of the road access – sealed or unsealed?

If these services aren’t yet available, you’ll need to factor in the cost and time involved in connecting them.

7. Slope and Site Levels

A sloping block can offer beautiful views and unique design potential, but it also comes with extra complexity. Steep blocks often require:

  • Retaining walls
  • Custom-designed slab or split-level construction
  • Additional drainage considerations

Flat blocks are typically easier and cheaper to build on, so always weigh up the benefits versus costs when considering a sloped site. Finding the perfect block means understanding these trade-offs early.

8. Future Development in the Area

It’s not just the current state of the neighbourhood that matters – it’s what’s planned for the future. Before buying, research:

  • Planned infrastructure projects (highways, train lines, schools)
  • Commercial or industrial development nearby
  • Subdivision potential or rezoning

These factors can increase land value over time – or reduce your quality of life if you end up next to a noisy main road or industrial park. This is a critical part of how to choose the right block with future-proof value in mind.

9. Building Restrictions and Covenants

Some land developments, especially in new estates, come with covenants or design guidelines that restrict what you can build. This may include:

  • Minimum house size
  • Roof colours and materials
  • Fence heights or front landscaping requirements

At SMG Construction, we always recommend reviewing these documents carefully with your builder or conveyancer to avoid surprises down the track.

10. Budget and Hidden Costs

Lastly, your budget is more than just the sticker price of the block. Be sure to account for:

  • Stamp duty
  • Site preparation costs (cut and fill, soil removal)
  • Connection fees
  • Bushfire or flood zone compliance
  • Council fees and permits

A seemingly affordable block could end up costing much more once all expenses are considered. This is why choosing the right block of land includes evaluating total site costs—not just land price.
