Dens are the architecture of childhood chaos and imagination. They’re portals to other worlds. But more than anything, they’re monuments to freedom - the kind of raw, unfiltered creativity that blooms when adults bugger off and kids are left with nothing but dirt and time.

And maybe we love building them with our own kids because somewhere in the back of our minds… we remember.

A scraggly conifer at the bottom of our garden. Its long, sweeping branches practically begged to be pulled back, revealing the kind of hideout MI5 would mark as 'inconclusive' after three classified flyovers. My twin brother and I stripped the non-essential limbs, reinforced the frame with strategic stick placement, and carpeted the forest floor with a thick, bouncy layer of pine needles. Four seasons. All-terrain. Bombproof.

We’d climb halfway up for recon missions, mostly to spy on Mum and Dad searching for us, whisper-laughing so hard we nearly drenched the brother below. It was our rogue outpost of rebellion, stocked with Hula Hoops and sibling scheming.

These days, I’m the one pacing the garden while two muddy misfits vanish into the shrubbery. So when a perfect summer’s day popped up last week - and we had 90 minutes to kill before Mum served up her dynamite fajitas - I did what any nostalgic dad would do: bundled the kids into the car after school and went off to build a den.

I had a plan. A patch of forest I’d scoped out weeks before. But like any great mission, we deviated immediately when I spotted a better spot mid-drive - a glorious mess of timber, shadows, and promise.

Even better, a nearby stream whispered its siren call. Within seconds, my son was hunched in ritual skimming stance beneath a moss-covered bridge. My daughter attempted to tightrope a mini dam, went down like a Shakespearean actor, and immediately declared shoes the tyrant. She went barefoot for the rest of the arvo.

Skim Lord hoisted Sole Sister onto his back and began ferrying her through the undergrowth. One of those moments of big-brotherly tenderness that makes you think: maybe, just maybe, you’re raising good humans after all. It was stunning. Proper childhood film montage stuff.

I’d packed snacks like a survivalist: a medley of fruit, crisps (BBQ Hula Hoops for a crunchy, zingy, finger-licking hit), and popcorn reserved for the triumphant topping-out ceremony. 

All but the popcorn was inhaled before a single stick was shifted.

Then came the moment of commitment. 

Jet found The Tree. 

A leaning, forked beauty. The sacred spine. The keystone. I launched into full Dad Mode.

They nodded like I’d just unlocked the secrets of the universe - then wandered off to poke ants with a stick.

Of course, the minute we got the frame up, both kids simultaneously announced their need for a bush poo. It’s always synchronised. I don’t know how or why. Off they toddled with sticks, like two giggling druids on a sacred ritual, with strict instructions to head at least 50 metres from the river, dig deep (15cm minimum), and cover it properly. No loo roll? No problem. Fern leaves to the rescue. Leave no trace, wipe with grace.

I kept building.

When they returned, the build was immediately abandoned for bug hunting. Skim Lord unearthed a pregnant woodlouse (“She’s got eggs! This is the best day of my life!”). Sole Sister began cataloguing Green Dock beetles with disturbing intensity.

Honestly? I love this bit. They’ve been obsessed with insects since growing up in Australia - and I’m all for nurturing it, especially now that a curious prod doesn’t risk full-body paralysis and a very expensive helicopter ride.

Eventually, we regrouped. The den took shape: three leaning walls and reasonably aerodynamic if the wind changed direction. Waterproof? Absolutely not. Structural integrity? Questionable. Could I have happily spent three more hours reinforcing the eaves and crafting a fern-lined porch with paracord and a hatchet? Without question.

We sat inside, basking in dappled sunlight and mild BO. Luna plated popcorn on a slab of bark like she was hosting a Michelin-starred forest supper. I leaned back and thought: this is the stuff.
