Since my last tree house was so popular I created another one. This is a double tree house made in 1.8 with decoration using MrCrayfish Furniture mod. I only decorated half of the tree house so anyone who wants to use my schematic can decorate the other half of the tree house anyway they want. Sorry it took a while to upload.
I turned off the fire place so no one will complain the treehouse burnt down.
Use /gamerule doFireTick false if you want to turn the fireplace back on.
