We build treehouses and cabins designed around nature.

Sustainability

Materials

We build with locally sourced, sustainably managed timber, working closely with trusted suppliers to source species that are both durable and environmentally responsible.

Our primary materials are Douglas fir and larch - fast-growing species native to England. Known for their natural durability, these timbers are naturally resistant to pests and rot, meaning they don’t need to be treated with chemical preservatives. This keeps harmful toxins out of your garden, your soil, and the wider ecosystem. It also makes them safer for bees, insects, and other wildlife that call your outdoor space home.

By choosing untreated, natural timber, we ensure that any offcuts can be safely composted, left to return to the earth, or burned in a domestic log burner—unlike chemically treated woods, which must be taken to landfill and pose a risk if burned.

We are fortunate enough to have sustainable managed woodlands next to our workshop, meaning we can source the wood for our cabin and treehouse builds completely locally. This fits in to our ethos of minimal environmental impact and design that’s sensitive to nature.

We always use FSC certified timber in our structures and avoid hardwoods that have a high carbon footprint such as those from Brazil and the America’s. It’s a choice that keeps our carbon footprint low, supports local forestry, and allows each structure to work with the surroundings to stand the test of time.

“These timbers not only stand the test of time but weather beautifully, blending into the landscape as they age. ”

For our balcony railings and decorative features, we use locally sourced coppiced chestnut and naturally fallen oak ‘stag’ wood. Coppicing is a traditional, sustainable woodland practice where trees are carefully cut back to encourage healthy regrowth, providing a renewable supply of timber without harming the tree. ‘Stag’ wood refers to dead branches that have already naturally fallen from a living oak.

For some of our cabin and treehouses, we use cedar for the shingle roofs, which provides a natural, durable solution. Unfortunately cedar isn’t widely grown in the UK, so we need to source it - choosing sustainably managed cedar from North America to ensure longevity and durability. Though the transportation adds the material’s carbon footprint, they are extremely resilient, making them a durable natural roofing choice. You can see them in action on the Wilderness Treehouse.

Supporting Reforestation Projects

We’re also proud to support reforestation efforts by donating a portion of our profits to tree-planting charities. Every project helps plant new trees, helping to restore woodland habitats for future generations.

A commitment beyond the build

Our approach to sustainability doesn’t end once your treehouse or cabin is complete. We offer follow-up checks after 2–3 years to ensure your structure remains safe and the tree remains healthy.
