    The process of constructing the home of your dreams is an amazing adventure. After all, you are just at the threshold of a brand-new and fascinating phase of your life. It is in your best interest to become familiar with the eight steps involved in the process of building a house in Australia. Doing so will make the experience as exciting and trouble-free as is humanly feasible.

    In this way, you will be able to know what to expect and be ready to overcome any challenges that may come your way.

    It takes much more than simply four walls and a roof to make a house a home. If you want to be able to make educated decisions on the customization of your future house, then the best research and preparation you can do is to gain an understanding of the building process. In the end, it is preferable to err on the side of caution rather than regret.

    The good news is that we have done the research for you and have broken it down into nine parts, beginning with contacting construction agencies and initiating the process of putting your plans into motion and ending with building your home from the ground up.

    Fail To Plan, Plan To Fail

    You will need to finish the preliminary stages of planning and preparation before you can lay the first slab of concrete. This is absolutely necessary. Because there is just too much ground to cover in the design process, we are going to gloss over the technicalities.

    After you've settled on a location and bought the land on which you intend to build, the next step is to devise a spending plan and sketch out a floor plan for your future home (either chosen or customised). It is time to evaluate what it is that you genuinely require as well as what it is that you desire. For instance, if you want the room to expand in the future for a potential pool, double garage, or if you just like feeling the sun on your face in the mornings, you should be reflecting on this now rather than trying to retrofit it later on. Another example would be if you want to feel the sun on your face in the mornings.

    You will furthermore need to address the preparation of the site and the zoning control. Before beginning construction on your new home, check to see that the state's zoning regulations, which might vary from one jurisdiction to the next, will be adhered to.

    Excavation And Foundations

    The moment has come to start looking for some heavy movers to come in and begin sculpting the terrain. You can, however, skip this phase entirely if the land on which you plan to build already contains residences and you do not intend to make any alterations that are very important.

    As soon as all of the debris and dirt has been removed, you should be able to get a good look at the floor layout of the house. This process can take anywhere from one to four weeks to complete, but it is typically quite straightforward because it does not depend on the complexity of the house's plan or whether the building of one part hinders access to other areas.

    The footings, which function very similarly to guide rails for the floor design of the home, are installed at this point. It is the bedrock and functions similarly to the foundation of an underground wall.

    Concrete or another substance of a comparable consistency is poured into a mould that has been cut into the dirt within the footings. It is necessary that it be of a sufficient height to direct water away from the structure.

    After making holes in the concrete for any utilities or power lines that need to be installed, pipes are inserted and the concrete is then patched and sealed.

    According to the Building Code of Australia, foundations are essential components of a building, and their inclusion is mandated by law. They not only serve as a foundation for the house, but they also prevent it from warping and expanding in certain terrains. In order to prevent termites and moisture damage, foundations need to be professionally planned by structural engineers. Implementations of the foundations are also required in order to provide ventilation for sub-floor areas and waterproofing that extends approximately 100 mm beyond the height of the soil.

    Due to the fact that many walls are formed through the processes of excavation and backfill, waterproofing is an extremely critical stage. After work has begun, the surrounding soil will typically need to be refilled past a portion of the height of the foundation, which will undoubtedly cause it to sink below the level of the soil and water. When you apply a waterproofing membrane, you effectively seal the water below the surface as well as above it, which stops dampness from creeping up from the porous underbelly.

    Cosmofin and Wolfin are the names of the two different waterproofing options that this project provides, and both of them can be installed at the level of the foundational membrane. Both of these German-engineered waterproofing sheet membrane materials have a high durability and have met the Australian requirement for more than 20 years within the industry. In addition to this, they offer the best possible level of protection across the board for any and all waterproofing applications.

    Basements, Cellars And Garages

    In addition to this, it is important to remember that buried or partially submerged rooms may indicate that development is taking place below the water table (ground and rocks are saturated with water). In this instance, we make use of a technique known as "below ground tanking," in which we instal a number of pumps with the intention of draining the water to the surface while construction work is ongoing.

    This process is carried on beyond the step of laying the basic foundation and continues until the final stage of building, which is the enclosing of the area with walls. Following that, it produces an efficient envelope for the space that is located between the soil and the membrane. Therefore, once the pumps have been removed and the soil has been backfilled, the submerged areas are shielded from any chance of water leakage, allowing the membrane to reject any additional moisture that may be present.

    Other Preparations

    If there are any installations that need to be done within the house, the best time to begin the process of acquiring a utility line is right now. Installing utilities such as water, sewage, electricity, internet, gas, etc. takes time and requires approval. This will be taken care of by your builder or contractor; however, you should verify that they have obtained temporary electrical service before building begins.


    The frame of a house is typically the first image that comes to people's minds when they think of a house that is being built.

    If the foundations and footings of the house serve as the horizontal reference plan for the construction of the home, then the frames serve as the primary assistance in the construction of the vertical. The skeletons and outlines of timber walls that are built by a carpenter are referred to as framing. In addition, framing will initiate the process of laying the tracks for the floors, roof, doorways, and window openings.

    Spend a large amount of time researching and selecting your company if you decide not to have children (which is by far the option that is the easiest). Because your carpenter will be one of the most important contractors working on your house, you will want to hire somebody who has a good reputation, is worthwhile, and who you can consult and trust to work with on an ongoing basis.

    The procedure can start once you've determined who will accompany you on the trip.

    Following the basic rectangular outline of the walls, the floor timber will be lined across an area with a wall and then built upwards to imitate the walls.

    Each of the wooden skeletons is held in place firmly by metal strapping; they must be robust enough to hold the construction of the roof as well.

    After that, boarding is installed for both the doors and the windows.

    At this point, you won't be constructing the actual walls, but you will be able to move freely across the space and have a good sense of how it will ultimately look.

    The unfavourable weather that has plagued this portion of the building process has been the most major obstacle, but fortunately, this is the last time that it will be an issue. The stage known as "Drying In" is an important phase of the frame process. This stage is the point in the process at which building can proceed even if it is raining outside.

    Roof Framing

    At this point in the process, the basic timberwork frame for the roof slating will be put up. You will also be waterproofing the roof at the substrate level if you choose to go with a flat roof as opposed to a pitched one.

    The main procedure of waterproofing at the roof stage is not all that dissimilar to the process at the ground level. Nevertheless, it is necessary to discuss it in a manner that is distinct from the remainder of the process of framing.

    The waterproofing solutions provided by Projex Group are designed to allow many finishing effects to be applied after installation or can remain exposed because they are resistant to the effects of ultraviolet light. Both Wolfin and Cosmofin are offered for purchase as fully operational systems.

    The membrane itself as well as the factory-bonded PVC profiles, prepared internal and exterior corners, detailing strips, adhesives, and welding solvent are all included with the purchase of one, making it the "complete waterproofing solution."

    Slats And Sheathes

    Before beginning work on the interior, this is the last big item on the checklist to be completed. Oriented strand boards, often known as OSB, are inserted into the spaces between the timbers to serve as a basic wall covering. This not only protects the home from the elements, but also acts as a true backbone for both the interior and exterior walls.

    Your carpenter will typically instal your windows and doors at this stage for the sake of simplicity and ease during the construction process. Now that these have been erected, sealed, and finished, the home is effectively wind and weather-proof, and it is ready for the next phase of construction, which is the internal work.

    During this period, it is a good rule of thumb to begin purchasing items and preparing ahead for your internal projects. If you give your crew plenty of time to prepare cabinets, installations, utilities, and work surfaces well in advance of when they are needed, they will be able to start working with the real model specs and instantly slot them into construction.

    Presentational Exterior

    Now that the skeleton of the house is finished, you can start working on the exterior according to the style you have in mind. Again, your external siding, which may be brick or an outer stucco wall, will be laid here regardless of what material you ultimately decide to choose.

    Your house will start to take shape in a way that makes it appear as though it could be lived in once the exterior siding is finished being installed. On the other hand, there are a few finishing touches that still need to be completed on the exterior.

    The majority of it consists of a succession of straightforward additions like soffits, the covering of any architectural overhangs with tiles or slating, and any friezes that you would wish to display.

    In order to stop any more seepage or leaking, the roof must first be tiled or shingled, and then it must be flashed with sheet metal or lead. Both of these steps are necessary. Unless, of course, you opt to use our Wolfin or Cosmofin systems in conjunction with a flat roof.

    Make a plan for the placement of balconies and terraces all around the exterior of your home, and decide whether or not to include them. Before screeding to falls and tiling the balcony, waterproof membranes should be laid directly onto the substrate. This is true regardless of whether the balcony's substrate is concrete, timber, fibre-cement sheeting, steel, or another material.

    When your walls have taken on the appearance of walls and your roof has taken on the appearance of a roof, it is time to begin bulking up the interior.

    Interior Utilities

    Take note that, unless there are multiple extraordinary factors at play, you should be able to save time by performing the external work mentioned throughout step three simultaneously with step four and any other internal design. This is the case unless there are multiple extraordinary factors at play.

    Lines And Piping

    The first areas of the interior that you should now cover are those for which we laid the groundwork during the stage where we were responsible for laying the foundation. The outside and covering have been finished, and the drying-in process has come to an end, so there is no longer any danger from the elements of the environment or the weather.

    The following is a brief check list of the items that you should be considering for this stage (including aspects such as electricity that your builders should be subcontracting regardless):

    • Permanent electrical fixtures (separate from any temporary ones used during construction).
    • Phone lines.
    • TV Lines (if separate).
    • Internet wiring.
    • Plumbing and sewerage.
    • Any security systems you'd like to install.

    In the future, you will be able to set these up after you have completed a speedy (and mandatory) safety check. You are not actively connecting the wires to the various services and appliances; all you are doing is laying the framework, which takes the form of wires.

    Before any drywall or plasterboard can be laid, the spaces in between the wall framing will need to have insulation batts installed. You won't need a lot of time or specialised knowledge to do this task, but it's better to get it out of the way sooner rather than later.

    Don't forget that investing in insulation and ventilation for your roof might be a smart move for preventing leaks and cutting down on your monthly electricity expenditures.

    Presentational Interior


    Plasterboard, which is more commonly known as drywall in the United States, can be fastened into place once the insulation has been installed. If you are looking at tutorials, you can now begin this process.

    Plasterboard is what you would consider to be a true interior wall because it is bonded directly to the timber framework and makes up the bulk of the wall. When this is in place, the walls are finished from a practical standpoint; from this point on, the only things left to do are add aesthetic touches and complete the places that contain fixtures, such as the doors and windows.

    Next, it can be worth your while to prime your plasterboard now in order to get it ready for painting in the future, but this decision will depend on whether you are using a painted trim or a wooden trim.

    Doing this now rather than later is recommended because there are no other big surfaces that need to be concerned with.

    For instance, after taping up doors and windows, you may be a bit sloppy with your covering without having to worry about getting a primer on the floor trim. This is because after taping up doors and windows, you no longer need to worry about getting a primer on the floor trim.

    You will be able to see defects in the plasterboard through the dried primer, giving this the ideal time to fill them in if you prime at this time. This is an added benefit of priming at this stage.

    You can skip this step if the trim around your windows and doors does not need to be painted. Considering a new project? Then MJS Construction Group builders Melbourne is the answer.

    Interior Trim

    At this point, you should have already sourced any permanent utilities, work surfaces, and cabinets that are necessary. After these have been affixed to your floor design, you will be able to start erecting any further inside trimming that you have planned.

    At this point, you should also think about finishing any painting or other installation of trim as soon as possible; if it is allowed to go unmanaged for an extended period of time, it can lead to warping.

    Final Utilities


    Assuming that you have previously completed the main installation of fixtures and the flooring, you can now call a plumber to complete the piping for any sections that need it. In this area, you will put in your bathrooms as well as certain components of your kitchen and laundry facilities.


    When the plumber is through with the basic setup, the electrician will come in and provide electricity to whatever installations have taken place.

    After this, the electrician will provide power to any utilities that still need to be finalised, such as the air conditioning, the lighting, the powerpoints, and the appliances.

    Water Retention Facilities

    Waterproofing is essential if you plan to establish a water retention facility on your property, such as a water tank, because it will ensure that the facility performs its function effectively. Since the majority of tanks are made of concrete or concrete-filled blockwork, the waterproofing solutions offered by Wolfin and Cosmofin are ideal for quick installation.

    These solutions are pre-formed sheet membranes that are supplied in a roll shape; they offer a more effective means of protection and are an alternative choice for the long term.

    Wolfin and Cosmofin Sheet Membrane waterproofing solutions, in contrast to liquid membranes, are immediately ready for installation and do not require any curing before the water tank can be used. This makes them superior to liquid membranes. In addition, these products are suitable for use in permanent immersion because they do not re-emulsify when exposed to water.

    Tidy Up, Scrub Out

    At this point, the house's main structure is finished; please accept our compliments. It looks like a house that could be lived in, if not an actual home, and from this point forwards, the great bulk of the work that needs to be done can be done by either you or professional interior designer.

    As a consequence of the construction of a house, there will be a large amount of accumulated garbage that has to be carted away, soil that needs to be filled in, worn walks that need to be made lovely, and landscaping that needs to be completed.

    It is recommended that you do all of this before moving on to the next step, as the next steps in the process need you to start with a relatively blank slate. For instance, saying things like an indoor carpet is an important next step, but it can't be done if there's debris and dust everywhere from the installation process since it can't be done if there's debris and dust everywhere.

    The Final Construction

    There are still a few odd works to be done, but the construction project has definitely started to wind down.

    Because it is impossible to construct a driveway until the vast flow of construction equipment slows to a trickle, you will invariably start working on it now rather than earlier in the process.

    In addition to this, now is the perfect time to start working on the landscaping. Again, unless you are going to go with pre-grown plants and rolled-out grass, this procedure will take a considerable amount of time to get properly settled in. As a result, you should begin as soon as possible in order to save time in the long run.

    It is also a fantastic time to use any leftover money in your budget to purchase some luxuries for your newly finished house so that it may truly seem like a "home" for you and your family. For instance, creating an enjoyable outdoor extension to your home by installing additional features like a louvred or sliding roof on a balcony can add significant value to the property and make the balcony more usable.

    Residential Waterproofing

    Throughout the entirety of the construction process, we have been emphasising how critical it is to ensure that the structure is watertight. However, this does not negate the significance of reapplying waterproofing now that you are nearing the conclusion of the process.

    In order to keep your home in good working order and free of problems, it is vital to waterproof the interior in an acceptable manner and shield the exterior from the effects of the elements. You can protect your belongings, including your furniture and other assets, against water damage by using appropriate waterproofing techniques.

    Roofs, walls, balconies, foundation pillars, and other critical spaces including bathrooms, toilets, kitchens, and laundries are examples of key locations that need to have their surfaces waterproofed. Waterproofing is required in these and other key areas.

    Frequently Asked Questions About Building A House

    The average cost to build a house in Australia in 2018 was $313,800. However, depending on its location and other factors, the price of an average-sized house can range from $271,000 to $1,124,550.

    Usually, 20% of the full value of the house is a good amount to aim for as a deposit. You can still get a loan if you have a smaller deposit, but you may need to take out Lenders Mortgage Insurance (LMI) which adds an additional cost to your loan. It'll also take longer to pay off.

    The average cost to build a 4 bedroom house is $1,900 m2 to $3,900+ m2, depending on the level of finish, materials and labour. Builders and architects often use a per square metre (m2) figure to cost a project, including a 4 bedroom house like yours.

    All costs include stamp duty. The cost of building includes land purchase, and assumes a first home owner concession on stamp duty where applicable. According to our figures, Perth is the only major Australian city where buying could be cheaper than building.

    Yes, you can build your own home in Australia if you want to cut cost and save money. You'll have to do an owner builder course if you're working on a project which costs over $12,000. Owner builder duties include: Supervise other contractors working under you.
