Construction and renovation

How do you build a house in Brisbane?

Work out the full budget, check the block, choose a builder and line up approvals and finance. Here's how the steps fit together, from your first quotes to moving in.

build-a-house-in-brisbane

Start by working out what you can spend on the finished home, including the land. Then check the block, choose a builder and design, and get the approvals and finance in place before construction starts. Some of these steps overlap: you can speak to a broker and builders while you're still looking for land.

The steps at a glance

  1. Set the full budget, including your repayments and costs while you wait.
  2. Check the block suits the home you want.
  3. Choose a builder and compare quotes for the same work.
  4. Arrange approvals and confirm the finance before work starts.
  5. Follow the build and payment stages, then inspect the home before handover.

Allow for the time before building starts as well as the construction itself. Ask for separate dates for design and approvals, the builder's available start and the expected finish. That is the schedule you need for rent, loan repayments and moving plans.

How much does it cost to build a house in Brisbane?

For a three-bedroom, single-storey brick-veneer project home on a level block, a rough planning range is about $2,400 to $3,000 per square metre including GST. This is our calculation from BMT's 2026 construction cost table, using its low-to-medium finish rates and Brisbane regional adjustments, checked on 1 October 2026.

At 180 square metres of gross floor area, that gives an approximate building estimate of $432,000 to $540,000. It is not a land-and-house package price or a quote for your block. BMT uses gross floor area, so check how garages and covered areas are counted when comparing plans. A sloping site, a different design or higher specifications can change the result.

Before deciding whether a build is affordable, add the land and everything needed to move in. These are the costs I would put beside the builder's quote:

  • Land and buying costs

    Contract price, duty where applicable, legal costs, searches and lender costs.

  • Building contract

    The work, allowances and inclusions written into the signed contract.

  • Costs outside the contract

    Site works, demolition, retaining, driveway, fencing, landscaping, window coverings, service connections or other exclusions.

  • Holding costs

    Rent or another mortgage, interest during construction, rates, insurance and moving costs.

  • Contingency

    Cash available for genuine changes or unknowns. Do not count the same money twice as the land deposit, buying costs and construction buffer.

This is an illustrative budget to show the calculation, not a client case, local land-price estimate or builder quote. Every amount below is an assumption. Replace each one with the price or allowance for your own project, and only add work separately if it is outside the building contract.

The $450,000 building contract becomes a $940,000 project in this example. The $15,000 buying-cost allowance is not a duty calculation; your solicitor needs to check the actual duty and concessions. The contingency is a budgeting assumption too. Check both the cash you need upfront and the repayments you can manage once the home is finished.

Queensland grants and duty

Queensland's $30,000 first home owner grant continues for eligible contracts from 1 July 2026. The home and land together must be valued under $750,000, and that includes any contract variations. For a building contract, the test uses the build price plus what the land is worth when you sign, not what you paid for the block. Other buyer, property and occupation rules apply. QRO: Grant eligibility.

Timing matters. If you apply through an approved bank or lender, a contract-to-build grant is generally paid with the first construction draw. If you apply directly to QRO, you generally wait until the home is finished and you've sent the required documents. Don't count on the grant for the land deposit. QRO: Payment and obligations.

For eligible agreements from 1 May 2025, the first home vacant land concession can cut duty on residential vacant land to nil, with no value cap. You need to build your first home on the land and move in within 2 years of settlement. For transactions from 1 August 2026, you also need to be an Australian citizen, permanent resident or specified foreign retiree. Duty still applies to any part of the land that isn't residential, and other conditions apply. Have your solicitor check the concession before you take duty out of your budget. QRO: First home vacant land concession.

Check the grant and duty concessions separately from your loan approval.

What should you check before buying the block?

Get a builder or designer to look at the block with your proposed home in mind. A block that fits the land budget can still need expensive excavation, retaining or drainage before the house will fit.

A cleared building site with foundation formwork marked out
  • Ask whether the home fits the frontage, slope, setbacks and access. Get soil and survey information before relying on a site-cost allowance.
  • Check flood information, planning overlays, easements and any building covenants. Ask what they mean for the design and the cost.
  • Confirm where water, sewer, power and stormwater connections will go, and which connection costs are included in the quote.

For a Brisbane City Council property, check new-house approvals and the FloodWise Property Report. Other councils have their own requirements. A soil classification does not establish whether land is contaminated; ask your solicitor which searches, such as the Environmental Management Register, and specialist reports the site needs.

Buying land, already owning it, or replacing a home?

If you're buying land now and building later, check whether you can afford both parts. A land approval does not guarantee a later construction approval. Income, expenses, rates, lender rules and valuations can change. My guide to buying land now and building later explains the finance options.

If you already own the block, the lender still needs to assess the proposed build, the land's value and any debt secured against it. If you're replacing an existing home, check the demolition restrictions and finance before booking the work. The knockdown rebuild guide covers that sequence.

Who checks what?

  • Builder or designer

    Whether the proposed home fits the block, access, slope and likely site requirements.

  • Solicitor

    The land contract, easements, covenants, disclosure, settlement dates and legal risk.

  • Relevant specialists

    Soil, survey, engineering, flood, bushfire, contamination or other site-specific matters where needed.

  • Hunter Galloway

    The land and construction loan, which lenders may accept the project, the valuation, your cash contribution and how progress payments will work.

How do you choose a builder and compare quotes?

Choose a builder with experience in the home and site you have in mind. Ask to see comparable completed work and speak with recent clients about communication, variations and how problems were handled.

Use QBCC's contractor checks to confirm the licence and history of the individual or company you would sign with. The name on the contract should match the licensed contractor. A trading name on a display home is not enough to identify who will do your work.

Ask two or three builders to price the same plans and specifications. YourHome's building guide recommends giving builders the design documents and asking for comprehensive quotes. A lower headline price tells you very little if one quote leaves out work the other includes.

  • Check the floor area, room sizes, fixtures and finish levels are comparable.
  • Compare site works, foundations, retaining, drainage and service connections.
  • Mark any allowances for items you have not selected or work the builder cannot fully price yet.
  • List exclusions such as driveways, fencing, landscaping, floor coverings or window coverings.
  • Confirm who arranges plans, engineering, approvals and the building certifier, and whether their fees are included.

Have your solicitor review the contract and explain the deposit, payment dates, variations and delay provisions before you sign. QBCC says a domestic building contract must be in writing and signed and dated by both parties.

For Queensland domestic building contracts of $20,000 or more, the usual maximum builder deposit is 5%, with a limited exception for substantial off-site work. That's a building-contract limit, not the lender's contribution requirement.

Check finance early, then line up the contract and lender requirements with your broker and solicitor. The bank may need the signed contract for its final assessment, so get advice on the commitments and dates before signing it.

What approvals do you need to build in Brisbane?

Planning approval and building approval are separate checks. Brisbane City Council says some houses can proceed as accepted development if they meet the relevant rules. Others need a development application, including proposals affected by certain overlays. Check the address and design before assuming approval is straightforward.

All new houses need building approval. A licensed building certifier assesses the building plans; Council says you will need detailed, scaled plans prepared by a draftsperson or architect. Put responsibility for engaging the certifier into the contract and ask who will organise the required inspections.

Your builder, designer or town planner can help establish which approvals your site needs. Get the expected time and fees into the budget. If your block is in Logan, Ipswich, Moreton Bay or another council area, use that council's planning rules.

How do you organise the land and construction loan?

Speak to a broker while you're setting the budget, then return with the property and building documents when you have them. The early conversation helps you work out a realistic price range. The later assessment checks the actual land, contract, finished value and your financial position.

The lender needs to be satisfied that the approved loan and your contribution can cover the project it agrees to fund. Check when your savings must be used and how the land settlement, builder deposit and first draw will line up. Keep enough cash for rent or an existing mortgage while the home is being built.

What should you have ready before applying?

  • land contract and settlement date
  • signed fixed-price building contract
  • plans, specifications, inclusions and exclusions
  • progress-payment schedule
  • quotes for essential work outside the contract
  • evidence of savings and where the rest of the contribution is coming from
  • current income, expenses, debts and credit-card limits
  • details of any rent or mortgage paid during the build
  • any existing land or finance approval

Lenders usually ask for a signed building contract, plans, specifications and a progress schedule. Include quotes for essential work outside the contract so the lender can assess the full project cost. Ask what is approved now and what the lender still needs before it will release money.

What if the bank values the finished home lower?

The lender usually values the finished home as a whole. It does not simply add the land price to the builder's invoices. Two valuers can reach different conclusions.

Two redacted valuation extracts showing finished values of $750,000 and $713,000, a difference of $37,000
Two valuers can reach different finished values for the same proposed home. That difference can change the cash you need.

Two valuers were $37k apart on the same proposed home

  • Higher finished valuation

    $750k
  • Lower finished valuation

    $713k

The valuation difference does not always equal the extra cash required. Your deposit, loan amount and the lender's assessment determine the final shortfall.

If the valuation is low, the answer may be a different valuer or lender, a smaller build, more cash, a changed contract or walking away before the deadline. The right choice depends on why the value is low and what the contracts allow.

The order of approval matters particularly when there is already a home on the land. This is why I would check the finance before committing to demolition.

A Queensland build I helped finance

One lender wanted the house knocked down before approving the rebuild

Aaron and Rebecca owned an older home worth about $685k with a $500k mortgage. Their plan was to demolish it and build a new family home.

The first lender wanted the existing house demolished before it would give formal construction approval. That would have left them with a vacant block and no certainty the build loan would be approved.

I compared another lender using the current land value and the $1.12m value expected when the new home was finished. The $810k total loan was approved before demolition started.

That order mattered. They could arrange demolition knowing the construction finance was already in place, instead of knocking down the bank's existing security and hoping the approval followed.

If you're replacing an existing home, my knockdown rebuild guide covers the full sequence.

What happens during construction?

Once the required approvals and finance are in place and the builder is ready to start, the job moves onto site. A typical build runs through site preparation and foundations, frame, enclosure, internal services and fit-out, then completion. These are a guide to the physical work. Your contract sets the payment stages.

Ask the builder to separate the time for design and approvals, the wait for a construction start and the time on site. Check the contract's completion period and provisions for delays. Weather, site problems, materials and changes can affect the programme, so leave room in your accommodation budget rather than booking a move against an optimistic finish date.

How construction payments work

A construction loan is normally released in stages as work is completed. The builder sends an invoice, you check it, and the lender may require its own form or inspection before releasing money.

Workers levelling concrete within foundation formwork
The completed work needs to match the payment stage described in your contract.

The stage names, percentages and timing come from the signed building contract and the lender's process. There is no universal 5-stage or 6-stage schedule that applies to every build.

Hunter Galloway videoWatch: the stages of building a home

My guide to construction loan progress payments covers what to check before each builder invoice.

During construction, interest is generally charged on the amount already drawn rather than the whole approved facility. Your exact repayment setup depends on the loan.

QBCC warns that paying a progress claim early, or paying more than the contract allows, reduces your protection under the Queensland Home Warranty Scheme. If the work or invoice is disputed, speak with the builder and get advice before authorising the payment. An independent building inspector can advise on completed work and defects.

Before agreeing to a variation, check the new total and whether the lender will fund it. A builder agreeing to extra work does not mean the loan has increased. If the remaining money will not cover completion, use the guide to construction cost overruns and contact the broker or lender managing the loan.

What happens at handover?

Arrange a practical completion inspection with the builder and consider having an independent building inspector attend. QBCC explains that practical completion can include minor defects or omissions. Record any agreed outstanding items and how they will be dealt with.

Handover has separate steps: practical completion, the bank's final payment and fixing defects. A minor defect doesn't automatically let you hold back the whole payment.

  • Check the home against the contract, plans and agreed variations, and document any defects or missing items.
  • Confirm what inspections, certificates and other documents are required before the lender releases its final payment.
  • Agree the handover arrangements, collect keys and warranties, and check when your home insurance needs to start.
  • Keep the contract, approvals, payment records and defects list together. Ask how to report anything you discover after moving in.

If you think the home has not reached practical completion, tell the builder in writing and get advice on your contract and payment obligations. Avoid treating the bank's inspection as a substitute for your own building inspection.
