The difference between a cubby house that gets climbed on, played in, and loved for eight years and one that sits ignored after six weeks comes down to three decisions: choosing the right age range, matching the design to your actual backyard space, and picking features that grow with your child instead of being outgrown by their fourth birthday.
At Hide & Seek Kids, we've helped thousands of Australian families set up backyard play spaces across Queensland and beyond. The questions parents ask before buying are nearly always the same. This guide answers them with specific, practical detail.
AGE SUITABILITYWhat Age Is a Cubby House Actually For?
A cubby house isn't one-size-fits-all. The right structure for a 3-year-old is completely different from what holds the attention of an 8-year-old.
Ground-level cubby houses work best for children aged 18 months to 5 years. These structures sit directly on the ground with no elevated platform, no ladder access, and typically include a single doorway, window openings, and sometimes a small serving hatch. The Marlie Cubby is a good example. It's enclosed, safe for toddlers under supervision, and creates a contained space where imaginative play happens naturally.
Elevated cubby houses with slides and platforms suit children from 3 years upward. Platform heights vary. A cubby with a 900mm platform is appropriate from age 3. Taller platforms around 1200mm to 1500mm are better suited to kids aged 5 and up. The Frankie Grand Cubby includes a wave slide and elevated platform that works well for this age bracket.
Most kids stop actively using cubby houses between ages 9 and 11. That's not a product failure. It's developmental. By age 10, most children want different types of play: physical challenge, sports equipment, or social spaces rather than enclosed imaginative play structures.
If you're buying for a 3-year-old, buy for a 7-year-old. Choose a structure with enough height, platform space, and add-on potential to stay interesting as they grow. A ground-level cubby feels perfect at age 3 but too small by age 5. An elevated cubby with a slide holds attention much longer.
SPACE REQUIREMENTSHow Much Space Do You Actually Need?
Most parents underestimate how much clearance a cubby house requires. The structure's footprint is only part of the space calculation.
Australian safety standards require 1.8 metres of impact-absorbing surfacing in all directions from the equipment perimeter. This is not a suggestion. If your cubby house has a 2m x 2m footprint, the actual required space including safety zones is approximately 5.6m x 5.6m. That's over 31 square metres for what looks like a 4 square metre structure.
For a cubby house with a slide, add the slide length to your calculation. A 1.5 metre wave slide needs 1.8 metres of clear space at the slide exit, measured from where a child's feet would land. This means the slide itself plus nearly 2 metres beyond it.
Minimum backyard sizes by cubby type:
- Ground-level cubby (e.g. Marlie): 4m x 4m minimum usable space
- Standard elevated cubby with slide: 6m x 6m minimum
- Large cubby or fort with extended platform: 7m x 8m minimum
Measure your yard before browsing product pages. Use tent pegs or garden stakes to mark out the actual footprint plus safety zones. Walk around it. Picture the full structure in place, not just the base. This avoids expensive mistakes.
Overhead clearance matters too. You need at least 6 metres of clear space above the equipment. Low-hanging branches, clotheslines, and power lines all create hazards.
TIMBER VS PLASTICTimber vs Plastic: Which Lasts Longer in Australia?
Timber cubby houses last 10 to 15 years in Australian conditions when properly maintained. Plastic structures start to fade, crack, and become brittle after 5 to 7 years, particularly in full sun exposure.
Hide & Seek Kids uses untreated timber for all cubby houses. This is intentional. Chemical treatment compounds are not appropriate for play equipment in constant contact with children. Parents sometimes assume untreated timber is a cost-saving measure. It's not. It's a safety decision.
Untreated timber requires maintenance. Apply a timber oil or outdoor wood stain every 2 to 3 years. For properties within 5 kilometres of the coast, annual treatment is non-negotiable. Coastal salt air accelerates weathering significantly.
Timber stays cooler than plastic in summer. This matters in Queensland and northern New South Wales where a plastic slide in January becomes unusable. Timber also weathers naturally. A plastic cubby looks progressively worse as it ages. A timber cubby develops a silvered patina that many parents prefer.
The full comparison is covered in detail on our maintenance and care page.
FEATURES WORTH PAYING FORWhat Features Are Worth Paying For?
Not all cubby house features deliver equal play value. Some get used daily. Others look good in photos but add little to actual play.
Slides: Wave vs Straight
Wave slides are more popular with children aged 3 to 8 than straight slides. The curved profile is more fun and takes up less ground space. Slide length matters. A 1.2 metre slide is fine for a 4-year-old but feels too short by age 6. A 1.5 to 1.8 metre slide holds attention longer.
Platform Height
Higher platforms extend the useful age range of the cubby. A 900mm platform is appropriate from age 3. A 1200mm to 1500mm platform suits ages 5 to 10. If you're buying for a child under 5, consider where they'll be in two years. A taller platform with supervised use when they're younger gives you more years of active play.
Climbing Wall vs Ladder
Climbing walls require more upper body strength and coordination than ladders. Most children under 5 find climbing walls difficult. Ladders are the safer, more accessible option for younger kids. Climbing walls work better as an add-on for children aged 6 and up.
Add-Ons That Get Used
The most-used cubby house add-ons are:
- Sandpits underneath the platform (constant play from ages 2 to 7)
- Chalkboards (cheap, simple, high engagement)
- Steering wheels and pretend shop accessories (peak use ages 3 to 6)
- Shade sails (practical, not just a play feature)
Features That Look Good but Add Less Play Value
Periscopes, telescopes, and decorative add-ons get used enthusiastically for the first few weeks and then largely ignored. They're not bad purchases, but they don't extend the play life of the cubby the way a sandpit or climbing wall does.
Honesty here builds trust. Buy the structure first. Add accessories after you see what your child actually uses.
COUNCIL APPROVALDo You Need Council Approval for a Cubby House?
Most cubby houses in Australian suburban backyards do not require council approval. That's the direct answer.
Approval becomes necessary when specific triggers are met. These vary slightly by state and council, but the common thresholds are:
- Height above 3 metres from natural ground level
- Placement within 900mm of a boundary fence
- Total floor area exceeding 10 square metres
- Heritage overlay or character housing zone
A standard elevated cubby house with a slide placed in the middle of a suburban backyard usually falls under exempt development. Check with your local council if you're uncertain. Most councils have an online tool or a planning officer you can call for a quick yes or no.
Before any ground anchoring or concrete footings, call 1100 (Dial Before You Dig). This is a legal requirement in Australia. The service marks underground utilities including water, gas, electricity, and telecommunications. Hitting a service line during installation is expensive and dangerous.
More detail on council rules by state is available in our FAQ section.
SAFETY STANDARDSSafety: What Australian Standards Actually Mean
Hide & Seek Kids cubby houses and forts are manufactured to meet Australian standard AS/NZS ISO 8124 and US standard ASTM F963-17. These are not marketing claims. They're testable requirements that cover structural safety, entrapment hazards, and material toxicity.
What AS/NZS ISO 8124 Actually Covers
AS/NZS 8124.6:2016 is the primary standard for swings, slides, and similar activity toys. It tests structural stability, entrapment gaps, fall height limits, and anchoring requirements. The standard ensures the cubby house won't tip during play, collapse under load, or create gaps where a child's head, limbs, or fingers could become trapped.
Entrapment gaps are one of the most critical safety elements. Any gap in the structure must be either smaller than 89mm (too small for a head to enter) or larger than 230mm (big enough for a whole body to pass through safely). Gaps between these measurements create entrapment risk.
Soft Fall Surface Requirements
Grass alone is not sufficient under or around a cubby house with an elevated platform or slide. The Australian standard requires an impact-absorbing surface with a minimum depth of 300mm. Acceptable materials include bark chips, wood mulch, or rubber safety matting.
The soft fall surface must extend at least 1.8 metres in all directions from the equipment perimeter. Hard surfaces like concrete, pavers, or compacted soil are not appropriate in fall zones.
Ground Anchoring
Freestanding cubby houses must be anchored. Most Hide & Seek Kids structures include metal anchor plates or ground stakes. These work well in firm, compacted soil. For sandy coastal properties, soft ground, or high water tables, upgrade to screw-in ground anchors or concrete footings with post stirrups.
Post stirrups are critical if using concrete. The concrete anchors the stirrup. The timber post sits in the stirrup above ground level. Never embed timber posts directly into concrete. This seals moisture against the end grain and causes internal rot.
More detail on anchoring methods and safety surfacing is available on our installation and maintenance page.
COST AND VALUEWhat Does It Cost and Is It Worth It?
Cubby house pricing in Australia varies widely based on size, features, and materials. A basic ground-level cubby starts around a few hundred dollars. A large elevated fort with slide, climbing wall, and platform can run into several thousand.
The question isn't whether the upfront cost is high. The question is cost per year of active use. A well-chosen timber cubby house that gets played in daily from age 3 to age 10 delivers seven years of use. Divide the purchase price by seven. That's the annual cost. Compared to the price of organised activities, memberships, and entertainment over the same period, a backyard cubby house is excellent value.
If the upfront cost is a barrier, Hide & Seek Kids offers flexible payment options. Afterpay and Zip are available at checkout for smaller purchases. For larger cubby houses and forts, our in-house lay-by option lets you pay as much or as little, as often as you want, with no interest and no third-party apps. You can spread payments over 3 months or use the Christmas lay-by to lock in your order and pay it off before the holidays.
Longevity comes from two things: choosing a structure that suits your child's age range for at least 5 years, and maintaining the timber properly. Annual inspection, tightening bolts, and reapplying timber treatment every few years keeps the cubby safe and functional well into its second decade.
CHOOSING THE RIGHT CUBBYHow to Match a Cubby House to Your Family
Start with your child's current age and add 4 years. That's your target age range. If they're 3 now, you want a cubby that still feels engaging at age 7. If they're 6, you're looking at something that holds attention until age 10.
Measure your backyard and mark out the space including safety zones before browsing product pages. Use the measurements in this guide as minimums, not suggestions.
Choose timber over plastic for Australian conditions unless your yard is entirely shaded. Timber lasts longer, stays cooler, and weathers better in high UV environments.
Buy the base structure first. Add accessories after a few months of use when you see what your child actually plays with. A sandpit and chalkboard deliver more play value than decorative add-ons.
Check your local council rules if the cubby is over 3 metres tall, within 900mm of a boundary, or in a heritage zone. For most suburban backyards, approval isn't required.
Budget for ongoing maintenance. Timber treatment every 2 to 3 years and an annual safety check keep the structure safe and extend its lifespan well beyond a decade.

Frequently Asked Questions
What is the best cubby house for a 4 year old in Australia?
An elevated cubby house with a slide and 900mm to 1200mm platform height is the best option for a 4-year-old. This suits their current abilities while remaining engaging as they grow. The Frankie Grand Cubby is well-suited to this age bracket. Ground-level cubby houses work for younger children but are typically outgrown by age 5.
Should I buy a timber or plastic cubby house?
Timber cubby houses last 10 to 15 years in Australian conditions with proper maintenance, while plastic structures typically become brittle and faded after 5 to 7 years. Timber also stays cooler in summer, which matters in Queensland and northern NSW where plastic slides can become too hot to use. Timber requires treatment every 2 to 3 years, but the longevity and climate performance make it the better choice for most Australian backyards.
How much space do I need for a cubby house in my backyard?
You need the cubby's footprint plus 1.8 metres of clear space in all directions for impact-absorbing surfacing. A standard elevated cubby with a 2m x 2m footprint requires approximately 5.6m x 5.6m of total space. Add extra clearance for slides. Measure and mark out the full area including safety zones before purchasing.
Do cubby houses need council approval in Australia?
Most cubby houses do not require council approval. Approval becomes necessary if the structure is over 3 metres tall, within 900mm of a boundary fence, exceeds 10 square metres of floor area, or is in a heritage or character housing zone. Check with your local council if you're uncertain. Most have an online tool or planning officer who can confirm quickly.
How long does a timber cubby house last?
A well-maintained timber cubby house lasts 10 to 15 years in Australian conditions. Lifespan depends on timber treatment frequency, ground contact management, and coastal proximity. Properties within 5 kilometres of the ocean require annual timber treatment. Inland properties need treatment every 2 to 3 years. Proper anchoring and keeping posts clear of direct ground contact also extend lifespan significantly.
What age do kids stop using cubby houses?
Most children stop actively using cubby houses between ages 9 and 11. This varies by child, but the shift happens when they want physical challenge and social play spaces rather than enclosed imaginative play structures. Buying a cubby with sufficient platform height and add-on potential extends the useful age range. A well-chosen cubby purchased at age 3 should still be engaging at age 8 or 9.
