The answer is YES with conditions.
In Queensland, homeowners can build timber decks over concrete patios, empty swimming pools, septic tanks, air conditioning units, pool pumps, tiles, or pavers—provided access, ventilation, and structural requirements are met.
DeKing Decks helps to turn underused or unsightly areas into valuable outdoor living spaces with benefits like added property value, improved safety, reduced maintenance costs, and better moisture protection under the deck.
At DeKing Decks, we’ve heard just about every request under the sun—we’ve even built timber decks on top of people’s garages and carports.
Read on to find out where you can build a deck, and if there are any special things you’ll need to consider.
Yes. You sure can. This is a very common request. In fact, not only can you build a deck over a concrete patio, but doing so also provides a moisture barrier.
That’s right—the concrete can act as a barrier between the soil and your wooden deck to prevent excess moisture exposure.
Yes, you can. Options include:
Many people consider a pool to deck conversion. There is also the option of a sliding deck allowing you to keep the pool as well.
A deck over a pool can either cover it permanently, be a sliding or rolling cover, fill it in, or be poolside. Building a deck above a pool might be an appealing choice for homeowners who do not like the look of their pool area.
Many people choose to fill in the pool with soil and turf because it’s cheaper, but if you prefer a deck over your pool, DeKing Decks would be happy to make it happen.
Yes, you can do this as well. However, keep in mind that if you build a deck over a septic tank, you’ll need adequate space to access it and service it. You’ll also need space for ventilation.
Indeed you can. We often build what we call ‘privacy screens’ over air conditioner units as they’re not very attractive in outdoor entertaining spaces. But just be aware that you will need enough space for servicing and ventilation. The same applies to pool pumps.
Sure, why not? You can certainly build a deck over pavers or tiles, you just need to make sure that the pavers have been laid correctly and are nicely settled. If it’s a botched DIY job, more work might need to be done before you can build a deck safely.

Yes – concrete acts as a moisture barrier, reducing rot risk in Queensland’s climate when properly ventilated and flashed.
Absolutely – we design removable panels or access hatches so maintenance remains easy and compliant.
Filling in is usually cheaper upfront, but a well-built deck over a pool can add more long-term value and usable space. We can compare both options for your property.
