How to Build a Granny Flat from Bunnings – Step-by-Step, with a Shopping List
As well as having a frame and truss department, Bunnings also sells so many other things you need to build your granny flat.
Effectively, you can buy everything you need from the hardware store, to build your granny flat.
Below is a step-by-step guide of how you can plan this build, buying everything that you need with several trips to Bunnings along the way.
You can read “Energy Efficient Granny Flats – Save money and the Environment” for a list of great materials to build a granny flat that is energy-efficient .
“Bearers and Joists for Granny Flats – How to Do It Right” talks you through how to lay these.
- Lay your flooring – A standard type of flooring used is particleboard sheet flooring, but you can speak to your designer about this.
- Put the frame that you ordered up – By now, the frame that you pre-ordered should be delivered, so you can put it up, so all the walls of your granny flat are installed.
- Put your rafters or trusses in – Again, these can be purchased from Bunnings Frame and Truss department. If you have a skillion roof, you will need to fit rafters, if you have a pitched roof, you will need to fit trusses.
- Put the roof on – Typical choices for a roof material are Colorbond or tiles.
- Fit your windows – As mentioned previously, these would have been pre-ordered with your frame.
- Go back to Bunnings to purchase your sarking, and then install this – This is a wall wrap that you put on the exterior of, and underneath your windows, so it can shield against moisture, fending the water off from being able to get in through the windows.
- Organise and finalise the rough-in for your Plumber.
- Organise your Electrician to visit.
- Lay your external wall covering, and gutters, fascia and eaves – Generally, the external walls are either a brick veneer or cladding.
- Get your interior walls plastered, and insulation added into the frame.
- Have your waterproofing done in all “wet areas”.
- Have an internal joiner fit your doors, skirting and architraves – The joinery includes all rooms such as your bathroom, kitchen, etc. This can be done in whichever order you like.
- Lay down your interior flooring – This will have been chosen with your designer, and may be able to be purchased from Bunnings.
- Paint the walls, inside and out – You will have pre-selected your paint colours, but the paint, brushes and all other items you need, can be bought at Bunnings.
- Finalise fittings – Now the fun begins! You can add all the extras to the inside of your granny flat to make it functional and look lovely, such as the lighting, and a Kaboodle kitchen.
- Organise your Plumber and Electrician to come over again – This will be their last visit, where they do their fit-outs (also called finishes). For example, they will fit the toilet, taps, and light switches.
- Landscaping – An important aspect for the regulations of privacy for the granny flat, this can also just be a nice part of the build for those who find gardening enjoyable. The smallest amount of landscaping can make a huge difference to your granny flat, as it is a feature point.
So, you’ll want to ensure its aesthetically pleasant, by including things that you can purchase again at Bunnings, such as:

What Could Potentially Be Used as a Granny Flat?
There are still things that you can purchase from Bunnings that you could potentially convert into a granny flat, such as this shed.
You will have to make some changes, so your local Council will approve it for use as a “habitable area”. The changes include making alterations such as:
- Floor Drains – If putting in a bathroom, this room requires floor-drains cut-in for waste-water, and piped to your current system. You can do this by concrete-sawing the slab so the necessary plumbing can be installed, or laying an elevated concrete floor.
- Waterproofing – Any “wet areas” (i.e., a bathroom and laundry) must be tiled, fitted, and waterproofed and certified by an accredited Waterproofer who confirms there are no leaks, so you gain your Waterproofing Certificate.
- Electricity – You will need a professional electrician to come and perform the electrical work, so the shed turned granny flat has electricity. They will also need to come back and hard-wire a smoke alarm.
- The Completion – These are all the things to make your granny flat both functional, and look lovely. Again, all of this can be purchased from Bunnings, such as floor coverings, lighting, and painting.
*Please note – This shed has ceilings that are over the required 2.4m high (EXCEPT for the bathroom, which can be 2.1m). If not, these would have to be amended. This shed is also already termite-proofed and has windows. If not, these necessary amendments would have to be made.

New Zealand and Bunnings Flat Pack Granny Flats
It is actually possible to purchase a flatpack granny flat at some Bunnings stores. These are built off-site and then delivered to the property on which they are going to be built.
However, so far, this is only in New Zealand, particularly in the Tasman District (which is located in the northwest of the South Island of New Zealand).
To give you an indication, at the time of writing, a pre-fabricated flat pack was selling, in Australian dollars, exclusive of GST, from roughly:
They also have a three-bedroom, two bathroom option available, which has been their most popular.
They are called the Clever Living Co range, and their full list of inclusions can be seen here.
Not listed are the exclusions, which are floor coverings, and on-site services such as power, sewerage, stormwater, and water.
More than 50 of these were sold in the first 12 months they first became available.
Demand only continued to increase, with a builder in Christchurch getting at least two queries about these flat packs every week. They are an affordable and quick option, with a three-bedroom flat pack able to be finished on-site in only six to eight weeks.
Bunnings is currently saying they have no intention to sell this range in their Australian stores, due to the different regulations between states and local Councils, which can be seen in the below posts:
Whereas in New Zealand, all Councils will give approval to build these flat pack designs within two weeks (ten working days), as they are built with multi-proof certification.
Pictures of the flat packs, inside and out, can be seen in this article I found.
This post has a lot of the information that I wish I knew before I built my granny flat.
You can see the in my costs that I was quoted, and paid, $14, 861.00 for the frame of my granny flat.
This was from a massive factory on the Central Coast in NSW, close to where I live, that builds everything for home projects and granny flats. For this price, I got the frame, the roof, the trusses, and the rafters.
After I finished building, I got a quote for the same materials from Bunnings. This quote was much cheaper, only $10, 000 – so, if I had bought from Bunnings, I would have saved $4861.00.
So, if you’re ready to take several trips to Bunnings, see how you can build your own granny flat and save yourself a lot of money.
