So, you’ve been a proud homeowner for some time now but your family living space needs have changed? You’re probably thinking about making some major shifts, regarding your property. Should you move to a much larger house? Or would it be better if you renovated or extended your home?
On that note, many Australians, who are faced with such a dilemma, choose to remodel their houses, in order to accommodate their need for extra space.
If you’re on that path yourself, wondering and researching how much a house extension or conversion costs, keep on reading.
Let’s say, you’re done with the brainstorming of what you want to gain in terms of additional living space, be it a guest room, a granny flat, a conservatory-like living room or another bedroom.
You’ve come up with a rough budget to the extent of ‘I won’t go over such and such amount’. The next logical step is to approach a building or home improvement company in the hope to get a comparative and reliable price on their house extension project.
And this is where all sorts of quote-related pitfalls could gradually spring up. From missing to include any demolition work to forgetting to budget for any building cost overruns, you could easily get an estimate that is only seemingly matching the limit of what you’re prepared to pay.
No house remodelling company can give you a realistic price quote unless you complete a series of steps beforehand. You’ll need to contact all the professionals or private experts who can provide you with the required preliminary surveys and all necessary reports.
Getting an accurate cost estimation you need a detailed land survey by a registered land surveyor, a soil report by a geotechnical engineer, a concept design and a structural survey.
Only then an experienced quantity or building surveyor can offer you a cost estimate, based on the above, as well as on the present floor area rates for the type of extension you intend to have (same-ground, two-storey, etc.).
The building surveyor will include other costs, as well, such as the builder’s markup, GST and more.
After completing the exploratory project works stage, you can get an insight on what to budget for your dream house extension and start looking for a specialist to draw your plans.
You will need the plans to present to a builder, along with every other piece of document, you’ve gathered, and a list of all the materials, fixtures and fittings, in order to get a quote for the actual work.
Below, we list various possible fees and costs that you may need to budget for, depending on the specificity of your house extension project.
Not all of them will apply for your situation, especially if the home redesign work is on a small scale or, say, it involves conversion of an existing structure.
Project estimates, based on sq. m. rates alone, are never reliable. Still, they are used when approximate costs need be calculated.
The rates vary by location and are interrelated to the type of work, you intend to have done.
Just as a guide, you can expect to pay anything from $1,300 to $2,200 per sq.m. for a single-storey extension. For a two-storey house extension, the price rises often by 50%. Converting your loft into a usable space will cost you from $1,600 to $2,600 per sq.m., depending on the scope of work and the various fittings you want to be installed.
A garage conversion is probably one of the cheapest ways to create extra space that you can utilise for something more than keeping your clutter or occasionally store your car. You’re equally likely to get a quote of $7,000 or $ 32,000, depending on what you’re going to make out of your garage.
Estimating the cost of the building work is hard, as many factors play in the process. For instance, labour for some jobs will be charged per hour (around $70 per hour), whereas with other types of renovation jobs – tradesmen work per sq. m. (plastering, tiling, painting, etc.).
There are various project expenses, which may comprise the final cost of your house extension or renovation work. They’re unique for each house renovation, but here are the general ones.
Let’s look into some home extension ideas that can inspire you and even help you save some money in the long run.
A conversion of an existing room, structure or a separate building is often cheaper than building a brand new storey or an additional room on the same floor. So, you can get that needed extra bedroom out of converting your loft.
Incorporate a smart, passive design in your new extension to save on heating and contribute to the environment. You can take advantage of heaps of information on the matter from Australia’s guide to environmentally sustainable homes.
Be it through an easy-to-install decking, which won’t cost you that much, or by connecting two existing structures and enclosing the space in between entirely with glass – you can enjoy your garden in rain or shine, either way.
This is more or less a type of conservatory but done simply out of timber and glass. Whether you’ll turn it into a living room or a kitchen, it’s entirely up to you.
You can embrace a difficult landscape and erect a veranda-like structure that can be turned into an additional room and still continue to garden the area underneath it.
Working mostly from home? Then, why not design your office with better productivity and comfort in mind? It doesn’t matter if you’re planning to use your garage for your home office conversion project or you’ll create a quiet, ergonomic workspace under the stairs that lead to the upper floor.
Adding a second bathroom may prove a relatively costly venture but no doubt that it will be worth it! It’ll not only make life easier if you have a large family but it will also boost the resale value of your house.
