Cost of home extension

home extensions Adelaide Depending on the size of the extension, the cost of a home extension can range from $1,400 to $1,800 per square meter. The range will be different depending on the quality of finish and design. Still, it will include the essential elements of the build, such as walls and foundation, adding a subfloor and providing basic electrical wiring. Adding finishing elements and plumbing will cost extra. There are many costs to consider when calculating the cost of a home extension.

Most builders will not break down expenses by individual rooms. The groundwork cost is typically only 15 to 25 percent of the overall cost of the extension. Homeowners often agree to pay tradespeople only after all below-ground elements are complete. Some people will employ the services of an architect or architectural technician to design and plan the extension, while others will do D-I-Y (do-it-yourself) tasks.

While there are various types of house extensions, the cost of a second-storey extension will be considerably higher. A second-storey extension, for example, will require the demolition of the existing roof, installation of a new sub-floor, exterior walls, and a new roof. These expenses can add up quickly. So make sure you have enough money to pay for a second-storey extension before you start.

Materials to use

While choosing which materials to use in your home extension is a personal decision, you should remember that it is also practical. The suitable building material will ensure a harmonious flow with the new addition. For example, you can choose a modern product such as Scyon Walls’ Matrix(tm) cladding, which matches existing building materials like brick or stone. Another good option is Axon(tm) weatherboard, which is highly functional and will integrate seamlessly with existing materials. You can even use the same paint colour as the exterior – the only difference is the colour!

While brick is the standard choice, you should also consider other materials. Copper, glass, and wood are alternatives that can create different visual effects and suit different budgets. Copper, for example, will complement the brick of the original building and make the extension look modern and attractive. On the other hand, while glass looks fantastic, it can be more difficult to achieve energy efficiency standards and may not be as cost-effective as stone or brick.

Bricks are a popular choice for home extensions because they are affordable, durable, and look great. They’re also widely used; you can find brick fireplaces in most neighbourhoods. Another modern alternative is glass, which is relatively inexpensive compared to other materials. It can also create a sense of spaciousness and openness. Choosing a glass home extension is a good option if you don’t want to spend a lot of money but still want to achieve a modern aesthetic.

Before you begin your home extension, check with local building regulations. Generally, you’ll need to apply for a construction permit if your plan involves construction work. You’ll need to pay a construction permit fee based on the total cost of the construction work. Once you have this, you can proceed with your project. If you can’t obtain a building permit, you may have to spend considerable money on additional materials.


Depending on the size of the home extensions Adelaide, the timescale can vary from seven to fifteen months. The process could take as little as two weeks to complete for more minor extensions, but it will still involve several site visits and draft drawings. More complicated projects can take longer. The project’s initial phase involves preparing the site, digging out footings and foundations, and laying a damp course. Once this is complete, the extension process can start. Next, the homeowner must obtain planning permission, which can take a week to three months.

Before you start work, you should clearly know how long you can expect the project to take. It is crucial to avoid any unexpected delays and to ensure that everything is completed on time. Ensure that the contractor you hire provides an accurate timescale and communicates this to you beforehand. It would be best if you discussed any time constraints with the builder to complete the project within the desired timeline. The contractor should also be aware of any other building plans you have so that they can make appropriate plans and schedules.

Return on investment

Depending on the type of project, you can get a better investment return by making lower-cost improvements. For example, you can insulate your attic for $1,268 and add one hundred and twenty percent value to the house. The top five more profitable renovations regarding ROI are kitchens, baths, family rooms, and primary suite add-ons. Conversely, the worst-performing projects cost more than $40,000 and will add just six percent to the house’s value when selling.

Different home areas can add value, so consider adding an extra bathroom or large kitchen. Adding a garage can also add value to a family-sized house. Garages can also increase the value of a home, especially if it is in an urban area. In either case, the first step is to choose the right architect. It can be a minefield, but it is crucial to choose the right one.

Whether the ROI will be high or low will depend on the type of project and the trends in the housing market. If the ROI is low, it could be due to sentimental reasons or an unavoidable situation. An investment calculator can give you the insight to decide which home improvement is the right one for you. In addition, you can get a free quote from a professional if you’re unsure.
