The Stages of Building a House in Australia: From Slab to Handover

Building your dream home is as exciting as it is daunting, and understanding what happens every step of the process can relieve a lot of the stress that can come with building your own home. Each stage of construction is unique, and every step has its own requirements, inspections and milestones, with work progressing in a planned sequence from the very beginning all the way until the end.

If you're planning to build in Australia, knowing the typical stages of building a house can help you understand what your builder is doing, when progress payments may be due and what to expect before moving in.

At Second2None Constructions, we aim to help new homeowners bring their plans to life with a considered approach to the new home building process, whether you’re choosing to owner build or work with a licensed builder.

1. Site Preparation and Slab

Typical timeframe: Several weeks, depending on site conditions and weather

Before the main construction work can actually begin, the building site needs to be prepared with a slab being laid. There are a number of things that happen in this step, including clearing plants, removing unsuitable material, levelling the ground and completing excavation. 

Once the site is ready, the builder arranges the foundations in accordance with the approved plans and engineering specifications. For homes built on a concrete slab, this typically involves installing plumbing and other required services underneath the slab, preparing the ground, placing reinforcement and pouring the concrete.

The slab provides the foundation for the rest of the home, so the preparation and installation work must meet the relevant engineering and building requirements.

Progress payment: The slab stage generally represents the first major construction milestone for a slab-on-ground home. The payment you will need to make is linked to the work completed and the payment schedule in your building contract.

2. Frame Stage

Typical timeframe: Several weeks.

With the foundations in place, construction can move into the next stage: the frame stage. This is when the structure of your home starts to take shape, making it easier to see the layout and proportions of each of your individual rooms, it’s also when you begin to really visualise your home. 

The builder installs the structural framework, including walls, roof framing and other structural elements specified in the plans and depending on your design, your frame may be made of either timber or steel. 

The frame must be installed in accordance with the approved plans and relevant structural requirements and an inspection is normally needed before construction progresses to the next stage.

Progress payment: The frame stage is typically associated with the completion of the home's structural framework. Your contract will specify when the payment becomes due and what work must be completed first.

3. Lock-Up Stage

Typical timeframe: Several weeks, depending on the design and materials.

The lock-up stage is when the home starts to become more like a functioning house, in the sense that it can now be shut up and protected from the weather. External walls, windows and doors are put in, while the roof covering and other external parts of the house also move towards being finished. 

The exact definition of lock-up depends on the building contract, but it generally means the home can be secured that it is enclosed enough to protect from the elements. 

This is a key milestone as it means other tradespeople can begin working on the interior of your home, without risk of their work getting damaged by vandals or by the weather. 

Progress payment: A lock-up progress payment is generally linked to the completion of the contractually defined lock-up milestone but you will need to check your contract to confirm exactly which work is included.

4. Fixing Stage

Typical timeframe: Several weeks to a few months.

The fixing stage focuses on the home's internal finishes and fittings and is the stage that your house really becomes a home. Your house is officially enclosed and the work externally  is complete, at this point, trades can begin installing the features that make the house functional and personalised.

This stage often involves several trades working in sequence, so the timeframe can vary according to the size of the home, the complexity of the design and the availability of materials and tradespeople.

Progress payment: The fixing payment is generally associated with completion of the internal fixing work specified in the contract

5. Completion and Final Checks

Typical timeframe: Several weeks, depending on outstanding work and inspection requirements.

As construction comes to a close, the attention shifts to finishing outstanding work, testing everything is in proper working order and ensuring the home is ready for handover.

The builder coordinates any remaining trades, arranges relevant inspections and addresses items that need correction. External works, connections, site clean-up and landscaping may also be completed at this stage, depending on what is included in the contract.

A pre-handover inspection is an opportunity to review your finished home against your agreed plans, specifications and contract. At this stage, you should be checking doors, windows, cabinetry, fixtures, finishes and the operation of installed services.

Progress payment: The final payment arrangements depend on your specific contract but before making the final payment, you should make sure everything is in order and that you have the proper documentation that you may need.

6. Handover & Collecting Your Keys

Typical timeframe: As soon as contractual completion and handover requirements have been satisfied.

Handover is the milestone that homeowners look forward to most once everything is completed and signed off, you can pick up the keys and prepare to move into your brand new home.

Handover does not necessarily mean every minor defect has been fixed and it’s important to know your rights and the process for addressing outstanding items. You can typically find this information within your specific contract. 

How Do Progress Payments Work When Building a House?

Progress payments are instalments made as construction reaches specified milestones rather than paying the entire building cost upfront, you typically pay according to the schedule set out in your building contract.

The stages commonly include the slab, frame, lock-up, fixing and final completion, however the exact milestones, payment amounts and requirements vary according to your specific contract.

How Long Does It Take to Build a House in Australia?

There is no single timeframe that applies to every new home. Construction can take several months or sometimes even longer depending on the project's size, design and how difficult the project will be to complete.

Factors that can affect the schedule include:

• Site conditions: Difficult access, excavation, soil conditions and drainage requirements can add time.
• Weather: Heavy rain and extreme conditions may delay foundations, roofing and external work.
• Difficult designs: Custom layouts and special materials can require additional time for your build.
• Trade availability: Construction relies on multiple trades completing their work in the right order, and within specific timeframes.
• Material supply: Delays in receiving particular building materials can impact the time it takes for your build.
• Approvals and inspections: The timing of required approvals, inspections and certificates can influence when work proceeds.

When you start thinking about building your new home, your builder should provide a project-specific schedule and make sure you are aware as soon as possible of any changes that affect expected completion.
