Can we build patio height above garage floor?

bow2021

Hi there,

we are going to start our courtyard area and trying to work out levels. Our house was built slightly below street level so trying to keep it as high as possible. We have marked out string lines with a 1cm fall per meter and as you can see by the picture this still doesn’t bring us to the bottom of our neighbours fence. I want to raise this more but the garage step down entrance won’t allow for this. My question is, would we be able to keep the garage level for the first meter or 2 on the patio (ensuring it drains away from the house) and then step up the rest of the patio? Would this be compliant in Victoria? Or is this just a bad idea?

thanks.

Hello @bow2021 

You're thinking along the right lines by prioritising good drainage and trying to maximise usable courtyard height. In Victoria, as in most parts of Australia, there are certain building code requirements around the relationship between outdoor surfaces and the dwelling, particularly when it comes to step-downs, drainage direction, and managing water near boundaries. The exact specifications can vary depending on site layout and whether the area is covered, so it's best to check with your local council or consult your builder or engineer to ensure compliance with the relevant standards.

In your case, having the first metre or two of patio level with the garage, so long as it still directs water away from the house is generally workable (always check with your builder/concreter for compliance). Some properties adopt this approach around garage entries or tight access points, and it can be an effective way to manage levels when there's limited height to work with. As you’ve considered, introducing a step up or change in level further out in the courtyard is a practical way to achieve a higher finished surface without compromising the garage threshold. This could be done with a low riser, a wide format paver transition, or a subtle change in grade.

While this approach can make the most of your space, it’s important that any surface water continues to drain away from your home and not toward the boundary or neighbouring properties. A licensed landscaper or concreter will be able to set your levels appropriately and advise on compliant fall and drainage solutions for your site. I also propose thinking about installing an Everhard 3m EasyDRAIN Polymer Grate And Prejoined Channel along the length of your garage entrance wall as a form of emergency drain should there be strong deluge of rainwater.   

To be certain everything aligns with Victorian requirements, refer to the Victorian Building Authority (VBA) for general guidance around waterproofing and paving near dwellings, or check with your local building surveyor or professional for site-specific advice. This will help you avoid drainage or compliance issues down the track and ensure your courtyard design is both practical and within regulations.
