Child's play looks to be serious business for some Swedish hotel-operators. Tree-houses designed as world-class hotel rooms are being constructed there in a bid to attract travellers who want to be closer to nature.

In a remote village in northern Sweden, a lofty new hotel concept which aims to elevate the simple treehouse into a world-class destination for design conscious travellers.

Treehotel - located in a place called Harads - will consist of four rooms when it opens on July 17th - each with their own distinct character.

The cabin is nearing completion, and is already up in the forest.

And the cube, which is the room that has garnered the most attention.

It will be attached to a single tree.

Four meters high and four meters wide, the walls are made with a mirrored glass.

Kent Lindvall, Treehotel Owner, said, "So everything will reflect in this - the trees, the birds, the clouds, the sun, everything. So it should be invisible nearly in the forest."

Lindvall says a special film will be applied to the glass which will be visible to birds.

Anette Selberg, Treehotel Sales Manater, said, "This is untouched forest and we want to maintain it the same way. We decided for example to not offer snowmobile safari which is very common up here."

Selberg is a native of this part of Sweden, but only moved back recently after living in Barcelona for a number of years.
