Whether you’re looking to offer additional housing for extra income or create an independent haven for a family member, you can accomplish this with relative ease and affordability thanks to Ross’s Discount Home Centre!

We’re all about creating affordable solutions – whether you’re building a new home, renovating, or in this case, looking to maximise your living quarters on a budget. With a little innovation and our help, you can easily convert a shed into a granny flat, offering the perfect solution for your accommodation needs.

Here’s what you’ll need to get started:

First things first, you’ll need to purchase a shed. You can find a wide variety of sheds made from different materials such as steel, aluminium, and timber from several Perth suppliers. We recommend opting for one made from steel or aluminium as they’re more durable and require less maintenance than timber sheds. If you want to create internal walls or dividers, now’s the time to do that also.

Once you’ve decided on the right shed and erected any walls and dividers you require, it’s time to start the conversion process!

How to Convert a shed into a Granny Flat

1. Install doors and windows

One of the first things you’ll need to do is install doors and windows. This will help to create a more comfortable living space as it will allow natural light and ventilation into the shed. If you’re planning on installing a kitchen or bathroom, you’ll also need to ensure that there are adequate ventilation fans installed.

Ross’s Discount Home Centre offers a wide range of Jason Windows’ doors and windows to suit any shed size or budget. We’re also the only supplier in Perth that stocks aluminium doors and aluminium windows, so if time is of the essence, you can rest assured knowing you can walk in and walk out with all your doors and windows on the same day!

2. Insulate the walls and ceiling

Once your windows and doors are installed, the next thing you need to do is insulate the walls and ceiling. This will help to keep your granny flat cooler in summer and warmer in winter, making it more comfortable to live in all year round. You can find insulation panels at your local hardware store.

3. Plasterboard the walls

Once the insulation is installed, it’s time to install plasterboard on the walls.

Of course, you could leave the walls steel or aluminium, however, the insulation will be visible and you want to create a granny flat that is warm and inviting… not a shed slapped together to look like a granny flat!

Plasterboard is easy to install and will allow you to paint the walls, creating the perfect finish for your granny flat.

4. Install Vinyl Flooring

The next step is to install sheet vinyl flooring. This type of flooring is easy to clean and maintain, and it’s also waterproof, making it ideal for use in a granny flat. You can find sheet vinyl flooring at most home improvement stores, or for a more homey look and feel, consider installing our SPC Vinyl Hybrid flooring, which is an affordable $30.00/m2

SPC Vinyl Hybrid flooring is a good choice if you want flooring that looks like wood but is softer on your feet. It always feels warm and comfortable when you walk on it.

4. Fitout the Bathroom

When creating a bathroom in a granny flat, you have to be conscientious of space. Therefore, it’s important to design the bathroom to maximise space. One way to do this is by installing a shower instead of a bath. This will allow you to have a larger vanity and toilet in the granny flat without sacrificing too much space.

For a simple shower solution, we have SMC shower bases and waterproof wall panels. However, if you’d prefer a traditional shower, our Brighton Shower Door & Return is a great choice. It’s available in 900mm x 900mm but still offers plenty of room to move around and get clean!

You’ll also want to opt for a compact vanity over a large vanity. We have a range of vanities at 75cm wide that are perfect for the job. Best of all, they are all pre-assembled for a super simple install.

Of course, no bathroom is complete without a toilet and tapware, and we have everything you need in this respect as well.

5. Install the Kitchen

Last but certainly now least is the kitchen. As one of the most important rooms in any home, you’ll want to make sure it’s well designed and equipped with all the essentials.

Ross’s Discount Home Centre’s pre-assembled DIY kitchen cabinets couldn’t be better suited for a granny flat! Our modular kitchen units allow you to create a kitchen of any shape and design, and all you have to do is screw them into place. No tedious assembly is needed. We also offer an affordable range of stone and laminate benchtops to complete your kitchen design.

When choosing appliances for your granny flat kitchen, go for smaller options that will still get the job done but don’t take up too much space. We also offer appliances and recommend our 50cm Freestanding Oven (White) for granny flats. It’s compact and offers a cooktop and oven, all-in-one.
