How long does a treehouse last?
A well-built bespoke treehouse lasts 25 years and beyond, with proper design and maintenance. Our oldest treehouse has stood for 25 years and is still in use - and as the longest-established treehouse company in the UK, we expect ours to grow old gracefully rather than be replaced. Lifespan depends on timber species, structural engineering, host tree health and annual inspection.

A treehouse lasts as long as the thinking that went into it. The species of timber matters, but so does whether the structure flexes with the tree rather than fighting it — and whether someone with the right eye looks over it each year. We design for movement, drainage and access for inspection from the very first sketch, because those decisions made on day one are what give a treehouse decades of adventure.
Most failures we are called to assess on other people's structures are not failures of the tree. They are failures of fixing detail, of trapped water, of timber chosen for price rather than performance. Get those right and the treehouse simply becomes part of the garden — quietly ageing, gently weathering, still loved.
Not relevant if you are looking at a flat-pack garden treehouse, a budget play platform or a temporary structure for a single summer. Those serve a real purpose and we have nothing against them - but their lifespan is measured in seasons, not decades, and the engineering, materials and maintenance regime we are describing here would be wildly disproportionate to that brief. For that kind of project, companies such as TP Toys, Plum Products or Wickey will serve you well.
Not relevant either if longevity is not part of why you are building. Some clients want something beautiful for a specific season of family life and are entirely at peace with letting it go afterwards. That is an honest choice. The pages on our Hub about cost, design and process will be more useful starting points than this one.
