How much will I pay for a Garage Conversion?

Want to transform your unused garage into a brand new living space, but unsure how much it’ll set you back? Read our handy guide to find out how much a building company will charge for a garage conversion.

What does a Garage Conversion involve? 

Let’s be honest, how many of us use our garages to store our vehicles? For most of us, garages are usually filled with junk, rendering them useless spaces. A garage conversion will turn your junk room into usable living space, increasing the value of your home at the same time.

Depending on the size of your garage and the layout of your home, there are various types of conversions you can undertake. For example, extending your kitchen or even creating a downstairs bedroom for elderly relatives or those with mobility issues. Other uses include a home office or a gym, making garage conversions extremely versatile. 

What is the average cost of a Garage Conversion? 

Garage conversions come in all shapes and sizes, and so do their costs! The price can be affected by the size, the finish of the project, and even location! 

To give you a general idea, here’s a breakdown of average costs based on local Australian professionals:

Type of garage conversionHighest average priceLowest average price
Small$10,000$5,000
Medium$15,000$6,000
Large$30,000$10,000

Garage conversions range in cost from $5,000 for the smallest and most basic finish up to $30,000 for large, high-spec conversions. As a ballpark figure, most homeowners will pay around $17,000 for their garage conversion, including external and internal works. 

Whether your project is on the lower or higher end of the scale, the advantages of a garage conversion are that it’s cheaper, not to mention less disruptive than an extension would be. Plus, it will add value to your home.

If you are converting the garage into an extra bedroom, it will also be cheaper and less hassle compared with moving house. 

Factors influencing cost 

Here are the main factors influencing the cost of a garage conversion: 

  • Other work involved 

  • Building regulation checks 

  • Your current garage space 

  • Usage types 

  • The value added to your home 

Other work involved

Even the most simple garage conversions involve quite a bit of work. On top of the actual building process, you’ll need to think about lighting, heating, power and insulation. The garage door will be removed and bricked up with a window added to the front. Towards the back, a door can be added or you can knock through to create one long extended space. 

In terms of cost, it depends on the size of the room as well as the spec of the finish you wish to aim for. New windows will set you back $450, and if they are aluminium or particularly high spec the cost could be higher.

Remember your quote will need to cover the building work itself, as well as the internal decoration. If you wish to hire an architect or interior designer the project will be more expensive.

Building regulation checks 

When it comes to getting a garage conversion, safety comes first. You’ll need to get building regulation checks carried out, costing you about $350 on average. This is necessary to ensure your garage conversion is fire regulated, energy-efficient, moisture-proof, structurally sound and that all the electrics are safe. 

Other considerations 

Knowing your garage would work better as a living space is the first step. But, you need to consider the space you have to work with, what you want to use the room for as well as the level of finish you want to achieve. 

Here are some additional factors to take into account when budgeting the overall cost of your garage conversion.  

  • Your current garage space 

  • Usage types 

  • The value added to your home 

Your current garage space

The first step is to consider your current garage space and crucially, the rooms it could potentially lead out onto. You’ll need to think about whether you want your room to be separate or attached to another room. Usually, a garage will have two access point options which sit to the side and rear of the room. 

Usage types

When it comes to different uses for a garage conversion, the sky’s the limit! Ideally, the extra space you will gain from the conversion should solve a problem you have. For example, needing an extra bedroom or a home office. 

If your garage is quite thin and narrow, it may not work as an individual room. Therefore, it won’t add as much value to your home. However, it can still come in handy as a utility room or even as a dining area if your kitchen is quite small. 

The usage type will have an impact on the type of internal work you’ll need to undertake, which will affect the completion time as well as the budget. 

The value added to your home

Although it might seem like an expensive project, a garage conversion could increase the value of your home by $60,000, especially if it’s a double garage or if an additional storey has been created. 

Of course, the true figure depends on your location, the scope of the work carried out and to what standard. Either way, given garage conversions are much cheaper than property extensions, it’s a much more affordable way to add value to your home. 

Getting a Garage Conversion - is it worth the cost? 

If you don’t use your garage to park your car, that space is going to waste. A garage conversion is worth the time and money because it will bring that space back into use. It can add a much-needed bedroom or dining space to your home, which ultimately will add value to your home. 

An additional perk of a garage conversion is that it increases your home’s curb appeal, especially if you carry out the work to a high spec. With a garage conversion, you can rest assured that you’ll add value and usage to your property.
