This Tree House Is Tops!

Tree houses are great places for children to play. But children who use wheelchairs cannot get up into tree houses. Bill Allen wanted to change that.

Allen built a special tree house in Vermont. It is 10 feet above the ground, and any child can get up to it. Instead of a ladder, there is a long, winding ramp.

The tree house looks like a fort. It is built around 21 trees. It has a roof, screens for windows, and electricity. If children in wheelchairs come up to this tree house, they can stay for the night. They can hear the sounds of the forest before they fall sleep in their bunk beds high off the ground.
