The perfect DIY treehouse

The best tree for a treehouse must be healthy, with well-shaped branches that are strong enough to hold the construction without being damaged. If the tree is deciduous, the treehouse is going to be shaded in summer and sunny through winter.

Choose the design

Once you’ve selected the tree, sit under it and make your plans. Ask the kids what they’d like and involve them in all aspects – the size, materials and design, including cost-related decisions.

How big do you want it to be? Will it be attached to the branches or supported by poles from the ground?

Does it need walls and a roof? If the tree has a thick canopy, perhaps a few strategically placed boards are enough.

Remember that the host tree is fundamental to your treehouse: allow it to grow without constriction and make sure the treehouse isn’t heavy.

Get permission

Building a treehouse might seem like child’s play, but there have been incidents where complaining neighbours have forced the removal of treehouses.

Avoid any disappointments by checking council regulations and discussing your plans with your neighbours.

Time to build

Now you’ve done the prep work, it’s time to start building.

1. Framework: Start by building a frame of three to four wooden planks bolted or lashed together, taking care not to harm the tree. Secure the support beams in the ground below and bolt them to the frame.
2. Flooring: Timber floorboards are best, or plyboard – make sure it’s weatherproof. Remember, it doesn’t need to fit together perfectly, as the tree moves anyway.
3. Walls and roof: If you want an enclosed cubby, you can either build these in situ or haul them up ready-constructed. Building them in situ gives you flexibility to work within the shape of the branches.
4. Windows: Unleash your imagination; make them round, triangular, huge, or a series of tiny ones. For safety, use perspex or leave them open to the elements.

Accessorise

Once the treehouse is in place, go crazy with the extras. Consider a rope ladder, commando net, solar lighting, cushions, crates for storing treasures or a rope for hauling up supplies.

When you’re building your kids treehouse, remember that it’s for fun and it’s in a tree – so enjoy that and don’t shut out the branches, leaves, birds, wind or sunlight.
