How to Build a Treehouse? Slow Life Inspiration from Hamakija.pl

Where parents' relaxation meets children's imagination. The story of our "tree" house
There are dreams you never grow out of. One of my greatest childhood memories was the vision of a real treehouse. Not just some ordinary plastic toy from a department store, but a genuine base for adventures. A place where you could hole up for an entire afternoon, create secret plans, watch the stars, hide treasures, and spend your holidays with the feeling that you have your own autonomous world.
A few years ago, I decided to make that dream come true… for my sons. That is how our house was born.
I spent about 4 months preparing the design myself. I wanted it to be more than just a regular playground - it was meant to become a space that the children would remember for the rest of their lives. A place for shared evenings, sleeping under the stars, and building family bonds. I entrusted the construction to experienced carpenters, but I created the entire concept, layout, and functionality step by step to suit our individual needs and the children's imagination.
A fortress with three entrances and a window to the world

From the very beginning, it was important to me that the children felt it was their own safe stronghold. Inside, there is a spacious living area that can be reached in three different ways:
-
Classic: up the wooden stairs,
-
Through the balcony: opening up the space to the garden,
-
Assault course: from below, up a ladder through a lockable hatch with a rope for rappelling – just like in a real commando base.
The house has two traditional square windows and one absolutely unique feature – a huge, round acrylic landscape dome. The children can safely lean out through it and observe their surroundings. It is definitely one of the most magical elements of the entire structure, which turns into a private astronomical observatory in the evening.

Cinema, hideout, and luxury survival zone
The interior of the house is a full-fledged living room, where we used solutions to ensure comfort at any time of day or night. The centerpiece is a huge sofa measuring 220 x 90 cm, which, when unfolded, creates a sleeping area of 220 x 180 cm. We lined the walls behind it with multi-colored felt panels, which dampen the interior and protect against the cold (as of recently, 2026 ;P ). A large mosquito net is mounted above the bed, so we can sleep in the house without any trouble even in the middle of a hot summer. And that is exactly what we do - for three years now, we have been regularly organizing summer sleepovers there with our sons and the neighborhood children. It’s like our own little survival experience, but in very luxurious conditions.
Inside, we couldn't miss elements that build a cozy, homey atmosphere. You will find a small table with chairs, cabinets for treasures, a chalkboard, and a corkboard for drawings, souvenirs from trips, and this is where the children hide their 'greatest treasures in the world' - stones, sticks, travel tickets, and small souvenirs that seem ordinary to adults but have huge value to them.
Once the windows are covered, the house turns into a cinema room thanks to the mounted projector and a pull-down screen for cartoons. Most importantly for us - inside, we hung two hanging chairs from Hamakija.pl. These are indisputably one of the most popular items on the agenda. The kids practically never leave them, treating them as a quiet zone with a book one moment and an element of dynamic play the next.

Climate controlled by an app
The house is fully electrified, and we manage the lighting system from an app on our phones. The children have three modes at their disposal:
-
Calm and gentle - perfect for winding down and falling asleep,
-
Bright play mode - based on three strong lamps,
-
Party mode - with a disco ball that turns the base into a dance floor.
The external LED lighting under the house also has variable colors. In addition, we mounted two classic lamps on the facade styled like old manor lighting, which create an incredible, warm atmosphere after dark. At the back of the structure, there is a 15-meter run of LED netting, and for complete safety during evening outdoor play, we equipped the area with strong floodlights and ground-recessed lamps buried around the entire lawn surrounding the playground.
Slow-life style playground
The house is the heart of the zone, but the garden buzzes around it. Attached to the structure is a slide, a climbing wall, a rope, swings, and a nest swing.
However, the most important zone from a parent's perspective is located right under the house itself. That is where we created a shaded space for a large family hammock. It is here that we most often catch a moment of breath in the spirit of slow life, relax after an intense day, and record the content for you that you see on our social media profiles. While the children above turn their base into a castle or fortress, we have our own sanctuary for relaxation below.
And sometimes... the house turns into a disco
When we designed the treehouse, we thought of a place for playing, reading books, sleeping over, and resting. We just didn't foresee one thing - that from time to time it would turn into a real dance hall.
A few colorful lights, the children's favorite music, and suddenly the whole garden comes alive. Laughter can be heard from far away, and the treehouse becomes a place where memories are born that you cannot buy in any store.
It is precisely these moments that most reinforce our conviction that building the house was one of the best family decisions we made. Not because it is perfect. Not because it looks like something from a catalog.
Because it is used every single day.
Sometimes as a secret agent base. Other times as a pirate ship. Sometimes as a place for a sleepover. And sometimes just as the highest dance floor in the area.
And I think that is what childhood is all about.
Before the colorful lights and dance evenings, there was the first night. A bit of excitement, a bit of uncertainty, and immense joy at being able to fall asleep in your own house high above the ground.

It is one of those texts we like to return to ourselves.
Construction for years - technical backing
A beautiful appearance is one thing, but safety and durability were the priority. The entire structure is set on solid metal supports with rubber insulation, which completely disconnects the wood from ground moisture and protects it against biological corrosion.
The ground under the house was properly compacted and covered with a 20-centimeter layer of washed sand with the addition of quartz sand, which provides a great visual effect and is safe cushioning during falls. We regularly protect the wood with specialized paint, which protects the material from UV rays and rain, while simultaneously allowing the structure to breathe.
Memories are what matter most
Today, with the benefit of hindsight, I know one thing. This is not just another garden structure. It is a factory of memories and a physical anchor of childhood. A place to which the sons run immediately after waking up and from which they do not want to return when darkness falls.

And I think that was the point from the very beginning. In today's busy world, the greatest luxury is not material things. It is time spent together, the space to develop imagination, and moments when we can simply be together without rushing.
In a few years, the house will probably change. The children will grow up.
But I believe that one day they will remember exactly these evenings - the lights under the house, sleeping together under the mosquito net, secret bases, and laughter carrying across the entire garden.
And I think that was the point from the very beginning.
P.S. As promised, I am sending the floor plan of the house ;)
