A new hotel is set to open in a faraway village in northern Sweden,which intends to change the simple treehouse into a world—class hotel for travelers who enjoy special designs.

Treehotel,which lies in Harads about 60 km south of the Arctic Circle,will be made up of four rooms when it opens on July 17th:the Cabin,the Blue Cone,the Nest and the Mirrorcube.

Two more are due to open in October—the UFO and A Room With a View.

“Our goal in five years is to have 24 rooms from 24 different architects(建筑师),”says Treehotel co-founder Kent Lindvall,who came up with the idea along with his wife Bfitta.

The first six rooms were designed by five different architects. The Mirrorcube which stands four meters high and four meters wide has drawn widespread attention as it will be connected to a singletree.

‘‘It’s an interesting building.You cannot find anything like this in the world today.It’s really special,”says Lindvall,as he stands next to the room’s mirrored outer wall.

‘‘Everything will reflect(映照)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 put onto the glass which will be seen by birds。

‘‘This is untouched forest and—we want to leave it as it is."says Selberg,another co-founder.

She adds.’’If we’re lucky we might see a bear.I think what’s exciting here is that we’re just 60 km below the Arctic Circle which means there’s a good possibility to have the northern lights in the winter and during the during the summer of course you have the midnight sun.”

The aim of Treehotel is “feel free in a tree” and the experience will cost up to 4,200 Swedish crowns ($555,50)for two guests in the Mirrorcube, which is designed to hold up to four guests.
