Choosing a block of land in Brisbane can start at a lot plan in a new estate, where the first two numbers you see are price and area. Both matter, but neither tells you which house designs will fit the block, how much site preparation it may need, or which rooms will get the winter sun.
Illustrative example: two lots in the same estate have the same area. One is wide, with the back yard facing north; the other is narrower, deeper and slopes towards the street. They can lead to different house designs, different site costs and a different feel inside the finished home.
This article covers four checks on a block of land that you can work through with the builder before you sign: orientation, frontage width, slope and site costs, and where the lot sits within the estate. The contract and title documents for the lot belong with a solicitor, and the article shows where that step fits.
In short: choosing a block of land in Brisbane comes down to four checks beyond price and area: orientation to north, frontage width, slope and the site costs it can bring, and the lot’s position within the estate. Each one can affect which house designs suit the lot and what the build may cost. The contract and title documents for the lot should be read and explained by a solicitor; Nextstar Realty does not provide legal advice.
What is different about buying a block of land in Australia
Start with the sun. Which way a house should face depends on where the sun sits, and a rule of thumb learned in another country may not carry over to Brisbane. Check 1 below sets out what the Australian Government’s Your Home guide says.
Two other differences are worth knowing before you compare lots:
- The block shapes the house design. Builders generally sell from a range of designs, and each design needs a minimum lot width once the setbacks from the boundaries are applied. A narrow block of land can rule out part of a builder’s range.
- Timing depends on the estate. In a new estate, a lot may be sold before the plan of subdivision is registered and the lot has its own title. In that case, the settlement date in the contract may be an estimate.
If you are buying the land as part of a package, choosing the block is one step inside that process. The two-contract structure is explained in how house and land packages work in Brisbane.
Check 1: orientation, and why north is the sunny side
The Australian Government’s Your Home guide explains the principle. Because the path of the sun in Australia is to the north, orientation is usually about whether the living areas of a home face north. North-facing rooms receive sun for the longest period of the day in winter and are easily shaded by the eaves of the roof in summer.
Under its heading on building a new home, Your Home suggests:
- locating living areas on the north side of the home for winter sun, with openings placed to catch cooling summer breezes and proper shading;
- using smaller, well-shaded windows to the south, east and west to increase cross-ventilation;
- avoiding west-facing bedrooms, for sleeping comfort;
- locating utility areas such as laundries, bathrooms and garages on the south or west side, where possible.
There is a climate layer as well. Your Home describes identifying your climate zone, as defined by the National Construction Code, as the first step in designing for climate, and notes that warm humid climates, meaning coastal locations above the Tropic of Capricorn, are the exception: there, orientation is about access to cooling breezes and shade. Brisbane lies south of the Tropic of Capricorn. Which climate zone applies to a particular block, and how it shapes a design, is a question for your builder or designer.
Your Home also notes that true (solar) north is not the same as magnetic north, and that the difference can be significant depending on where you live. When you compare one block of land with another, ask the builder to show each design on a siting plan with the north point marked, so you can see which rooms face the sun. The north arrow and other markings on a plan are explained in our guide to reading a floor plan, written in Vietnamese.
Check 2: frontage width decides which house designs fit
A narrower frontage often means a shorter list of designs. Builders generally design each plan for a band of lot widths, and the side setbacks take a slice out of that width. Two blocks with the same area but different proportions can produce two different lists of designs.
| Frontage | What it often means for the design |
|---|---|
| Narrower | Single garage, rooms arranged front to back, fewer side windows |
| Medium | Double garage, more layout options |
| Wider | Single-storey designs that spread sideways, more usable side yard |
The table shows a general pattern, not a rule. The builder’s range and the setbacks that apply to the lot decide the actual list.
Before you commit to a lot, ask the builder for the designs that fit that specific block of land and for a siting plan showing the house on it. It is easier to change your choice of lot at that point than to change the design later.
Check 3: slope on a block of land and the site costs it brings
The steeper the block of land, the more site preparation it may need: cut and fill, retaining walls and drainage. Those items sit in the site costs of a build contract, and they depend on the individual lot as well as on the design placed on it.
This article deliberately does not put a figure on site costs. Builders generally work site costs out for a specific block of land, using its contour survey and soil test results once they are available, so a general rate would say little about the lot in front of you.
The practical step is to ask rather than to estimate. Questions worth putting to the builder before you sign:
- Has a contour survey been done for this lot, and can I see it?
- Has the soil been tested yet, or are the site costs an estimate until it is?
- For this block and this design, which site preparation items are outside the standard price?
- If the soil test result changes the footing design, how does the contract deal with the difference?
The last question is also one for your solicitor. A sloping block of land can suit a split-level design and open up a view. What helps is knowing the likely scope of site works while you are still comparing lots.
The kinds of line item on a house and land quote, including site costs, provisional sums and prime cost items, are explained in our guide to site costs on a house and land quote, written in Vietnamese.
Check 4: where the lot sits within the estate
Within the same estate, the position of a block of land changes how a house can sit on it. The table below describes what is physically different about common lot types, and a question to take to the builder for each.
| Lot type | What is different about it | Question for the builder |
|---|---|---|
| Corner lot | Two street frontages, which can mean more open sides, more options for where the driveway goes, and more fencing | How setbacks and fencing apply to both frontages, and which designs fit |
| Cul-de-sac lot | Can have an irregular, wedge-shaped boundary | How much of the lot is usable for the house once setbacks apply |
| Lot facing a park | Open space next to or across from the lot instead of another house | How the design can face the outlook while keeping living areas to the north |
| Mid-block lot | Neighbours on both sides | Which designs fit the width between the two side boundaries |
A lot plan is flat, and a house on it is not. Looking at finished homes on similar lots, in the same estate or at a builder’s display village, can make the plan easier to picture.
Position also interacts with the first two checks. A corner lot with the street to the north, for example, puts the question of north-facing living areas and the question of two frontages on the same siting plan, so ask to see both answered together.
Before you sign: the contract, the land and the builder
Choosing the block of land is only part of the decision. Before you sign, three steps sit with other people.
- The contract and title documents. The contract for the lot, and the documents that come with it, should be read and explained by a solicitor. Nextstar Realty does not provide legal advice. The Queensland Government strongly recommends getting independent legal advice before you buy a home, and suggests asking your solicitor to check the sale contract before you sign.
- Where the land is up to. Ask the seller whether the lot already has its own title or is still waiting on registration of the estate plan, and ask your solicitor what that means for the settlement date in your contract.
- The builder’s licence. In Queensland, the QBCC licensee register lets you look up a builder by licence number or name, and QBCC says the register provides a complete licence history. The search is covered step by step in how to check a builder’s QBCC licence.
If you are buying a house and land package, the land contract and the build contract are separate documents, even when they are presented together. What happens after the land contract, from approvals to handover, is set out in the new build construction process in Australia.
The four checks on a block of land, and the step before signing
| Check | What to look at | Who to ask |
|---|---|---|
| Orientation | Which rooms face north on the siting plan | Builder or designer |
| Frontage width | Which designs fit the lot once setbacks apply | Builder |
| Slope and site costs | Contour survey, soil test, items outside the standard price | Builder; solicitor for the contract wording |
| Lot position | Street frontages, shape, usable area | Builder |
| Before signing | The contract and title documents for the lot | Solicitor |
Frequently asked questions
Which way should a block of land face in Australia?
According to the Australian Government’s Your Home guide, orientation is usually about whether the living areas of a home face north, because the path of the sun in Australia is to the north. North-facing rooms receive sun for the longest period of the day in winter and can be shaded by the eaves in summer. Your Home describes warm humid climates, coastal locations above the Tropic of Capricorn, as the exception, where orientation is about cooling breezes and shade.
Can you build on a sloping block?
Often, yes. A slope can suit a split-level design, and it can also add site preparation such as retaining walls and drainage. Whether a particular design suits a particular block, and what the site works may involve, is for the builder to confirm from the contour survey and soil test for that lot, so ask for both before you sign.
How wide does a block of land need to be?
There is no single number, because each builder’s range has different width requirements. A practical way to settle it is to shortlist the designs you like, then ask the builder the minimum lot width each design needs on the lot you are looking at, once setbacks are applied.
Does a bigger block of land mean a bigger house?
Not necessarily. Area is one factor, but frontage width and the setbacks that apply decide how much of the block you can build on. A deep, narrow lot can fit a smaller footprint than a squarer lot of similar area, so compare the designs that fit rather than the area alone.
Is the price of the lot the full cost of getting it ready to build?
Not always. Site preparation depends on the terrain and soil of the individual block, and some items may sit outside the builder’s standard price. Ask the builder which site costs apply to your lot and design, and have your solicitor explain how the contract deals with any estimates.
Next steps
Choosing a block of land is one of the harder decisions in the process to reverse: a house design can change, the block cannot. The four checks above can be worked through with the builder while you are still comparing lots, and the documents can go to your solicitor before you sign.
