Hello everyone. Please bear with me as this is my first Instructable, but hopefully not my last. This should hopefully serve as a rough guide for people looking to build a treehouse. At this point I must caution you though as treehouses can be very dangerous especially if they are built high up in a tree. My treehouse was built entirely by what popped into my head at the time of construction. I had no prior experience when constructing it and simply did what I thought would work. While my treehouse did turn out to be very sturdy I would urge you to consult an expert and use high quality parts to prevent disaster.
Step 1: Surveying
Begin by finding a sturdy, suitable tree in which to build your house. I was lucky and had a perfect tree right behind my house. My treehouse is about 10 feet off the ground on the first floor and 17 feet off the ground on the second floor. The higher you go, the cooler the treehouse (in my opinion) but also the more dangerous.
