Treehouses for adults: offices, retreats and guest rooms

The Treehouse Guide Design and Features

Treehouses have moved a long way beyond the traditional children's playhouse. Many of our clients now commission a treehouse as a sophisticated outdoor living space, somewhere to work, entertain or simply get away from the main house.

What an adult treehouse can be

  • A garden office
  • A reading room
  • A private retreat
  • An entertaining space
  • A creative studio
  • A yoga or meditation space
  • A private dining room
  • Guest accommodation

Comfortable all year round

With the right specification a treehouse can be used in every season. We can incorporate insulation, heating, electricity, plumbing, high quality glazing, hardwood decking and bespoke internal joinery. The result is a fully functioning room rather than a summer playhouse.

And there is something particularly special about working or relaxing among the branches. A well designed treehouse creates a real connection with the natural world. You sit among the leaves, look out over the garden and watch the seasons change from a completely different vantage point. It is not simply another room in the garden. It is a room in the trees.

Questions people ask

Yes, and it is one of the most popular uses. A well insulated treehouse makes a peaceful workspace surrounded by nature.

Yes. Electricity, lighting, insulation and heating can all be incorporated, depending on the design and the intended use.

Design and Features

What can you put in a treehouse?

One of the great advantages of a bespoke treehouse is that you are not restricted to a standard design. The treehouse is designed around the people who will use it and the way you want to enjoy it.

Cost and Budget

How much does a bespoke treehouse cost?

This is usually the first question we are asked, and the honest answer is that it depends on the treehouse you want to create. Our bespoke treehouses start from around £15,000. The final cost can vary a great deal depending on the size, the design, the trees, the access and the level of specification.

Trees

Which trees are best for a treehouse?

There is no single species that suits every treehouse. The health, size, structure and position of the individual tree usually matter more than what kind of tree it is. Two oaks standing fifty metres apart can have completely different characteristics. That said, after twenty years we have clear views on the trees we meet most often.
