Charlie's house in the tree

Charlie's Uncle have him a large block of land to build a house unfortunately it had a huge sink hole in the middle. It did have an enormous oak tee that reached to the clouds so he decided to build a house in the tree, to have a different room on every branch there were enough branches to have a very large house of sorts. He could have a bird house, a dog house, a bathroom, a kitchen and lounge room and a several bedrooms all on different branches. A Library, and maybe on a very large branch he could build a platform and have a ballroom, then he thought more about the possibilities he could have a swimming pool too. A funny story for you children.
