Birr Castle Treehouse

the brief

Welcome to the Birr Castle Treehouse


  • Sussex Business Awards – Winner 2014

Birr Castle is set in the Irish midlands, in County Offaly. It’s the home of the seventh Earl of Rosse and whilst the residential parts of the castle are closed to the public, the grounds and gardens of the castle (the demesne) are open to the public.

Among the main features of Birr Castle is the “Great Telescope”, built by the third Earl of Rosse in 1845. As its name suggests, it was the world’s largest telescope until 1917 when the Hooker Telescope surpassed it in size. As a result, the demesne is now also home to Ireland’s Historic Science Centre. Now the Birr Castle Demesne also boasts a breathtaking 3-story fairytale treehouse. Since the opening of the treehouse adventure playground, Birr Castle has experienced a significant increase in visitor numbers. The treehouse has also been featured in a wide variety of national and international press, including The Sunday Times, The Herald, Irish Times, The Irish Times Magazine and The Sunday Business Post.

the design

When it comes to designing playgrounds – there are no limits!

The Birr Castle Treehouse fits perfectly in the beautiful natural surroundings of the Castle, which is also home to some of the rarest tree species found anywhere in the world. Standing more than 3 stories high, the treehouse is the centerpiece for a new adventure playground.

The structure has been designed to resemble an adventurous fairytale castle, blending effortlessly with the architecture of the main castle and echoing elements of the build in its own design. Round turrets and Gothic-style windows transport the visitor back in time. Amongst the labyrinth of turrets, the Birr Castle Treehouse and Adventure Playground feature tree decks linked by rope bridges, secret tunnels, a giant bouncing pillow, hobbit house, sand play area, scramble nets and climbing rocks, swings and slides and a picnic area.
