The kids never asked for a tree house - but I decided to build them one anyway (perhaps that says more about me than them!)
Crafted mostly from an old pergola, sourced from a demolished house, the platform sits on a frame that avoids the need to dig post holes that would have impacted the tree's critical root zone. The fort sits within a Lemon Scented Gum which fills the air with a zesty smell when it rains. The structure includes a weather tight cubby, slide, rope ladder, gas lift trap door and pirate flag (obviously). Yaaaaarh!
Materials
- Recycled pergola timbers - main frame
- Recycled spotted gum boards - decking and some balustrade
- Treated pine (various sizes) for floor joists and cubby frame

Steps
Step 1
- Quick sketch design and check in with Bunnings Workshop community to seek advice!
- Clear and level ground around tree for base
- Lay and compact 20mm gravel for base of frame to sit on (to help provide a sturdy base and improve drainage)
- Paint all wood in contact with ground with Bondall wood protector
- Cut and fix timber with large screws
Step 2
- Cut and attach frame legs using M12 through bolts
- Cut notches in top of posts for frame sides, ensuring all plumb and level
- Install frame sides using M12 through bolts
Step 3
- Install joist hangers for joists using structural nails
- Install joists made from treated pine - size and spacing of joists based on expected deck weight and length of joist span
Step 4
- Install spotted gum decking on top of floor joists
- Install balustrade frame using cut lengths of spotted gum decking before installing branches collected from site as railings
- Treated pine used to create cubby frame with fence palings used for cladding - all fixed with treated pine screws
Step 5
- Final fit out including wooden ladder with climbing holds
- Rope ladder
- Trap door made from wood scraps and gas lift struts
- Install periscope, wheel and bell
- Add pirate swag (flag, spray paint decals)
- Encourage kids to stop watching TV and get outside!
Hello @mjkworldwide
What a fantastic treehouse, it looks very solidly built. It looks very well thought out and the stencils are a neat touch. The use of natural timber branches to cover the balustrade was very clever. I'm sure your kids will appreciate the treehouse. I also suspect that they will be asking for additions once they realize that the pirate ship can get bigger.
Thank you for sharing such an awesome project.
