Creating extra living space doesn’t have to involve extending your house. A self-contained dwelling – a granny flat – is an affordable way to expand, without the hassle of a full-blown reno. Check out this variety of backyard styles and sizes to spark your imagination. You could buy a kit, design and build your own or even convert your garage! Ready to start?
Can I build a granny flat?
It depends where you live. Vic and SA require granny flats be built for a dependent family member. In Qld and WA you’ll need approval if it’s for rent. In NSW, you don’t need council approval if it meets certain requirements. For more info, search your state gov website for ‘granny flats’.
How much will it cost?
Like all buildings, cost depends on size and construction methods. The 9 x 3.4m AJC Portables building used here comes as a shell, ready to fit out, for around $25,000, or fully completed and ready to go for under $34,000.
Here are some different types...
Now let's take a look at how to build the bits inside...
Here’s an overview of what this project will take. For complete instructions, please refer to the project sheet. You can pick up a flat-pack kitchen from selected hardware stores – they’re simple to put together and install.
Gather your supplies:
• Flat-pack cabinets, components and bench tops to suit
• Sink, taps, kitchen appliances
• 600 x 300mm tiles for splashback
You’ll also need:
Drill; spirit level; clamps; 28mm chipboard screws; heavy-duty castors; masking tape; jigsaw fitted with laminate cutting blade; tile adhesive; 6mm notched trowel; 3 and 1.5mm tile spacers; tile cutter; angle grinder fitted with diamond blade; grout; silicone sealant
Assemble cabinets according to manufacturer’s instructions.
Join cabinets and install. Adjust legs to make level and plumb. Screw to walls. Add castors to bottom of kitchen island.
Cut and install benchtops. Use jigsaw to cut holes for sink and cooktop. Fit wraparound benchtop to island, cupboard doors and drawer fronts.
To tile splashback, cut tiles as required. Spread adhesive on back of tiles and use spacers to create gap between tile and benchtop. Grout between tiles and silicone between benchtop and tiles.
