I share this all in jest of course because who attempts to build a treehouse after building a printer stand like that? I didn’t know where to start so I did quite a bit of research on the interwebs but full disclosure my primary resource in guiding me through this project has been this book (Amazon link HERE). It’s pretty simple read with lots of pics (who doesn't like pics?) but it covers a lot of things you may run into and stresses important things one might overlook. It also contains a lot of creative ideas - which is the fun part! I highly recommend it as a basic guide. Lastly, my advice to anyone attempting to build a treehouse is “plan ahead but expect the unexpected and be flexible”. Every tree and treehouse is different, and almost nothing goes exactly as planned so get ready to use your power drill clockwise (to assemble) and counterclockwise (to undo mistakes).
The Beams, Wood and Hardware
So the most important part of a treehouse are the beams. You cannot skimp on this part because this is what will be bearing the weight of your house (and your children!) and so it must be done right. As Jesus said, it’s better to build on rock than sand or the house will come tumbling down (i.e. your foundation matters!). I decided to go with two 2’x6’ beams on each side of the tree. The two oak trees I was securing the beams on are about 7 feet apart. If the beams were spanning much more than that I would have went with 2’x8’ beams but combining two pieces of wood is much stronger than going with one thicker piece (4’x6’) because two distinct cuts of lumber will have varying weak spots making the combined piece stronger overall. Yes, King Solomon was right when he said: Though one may be overpowered, two can defend themselves. A cord of three strands is not quickly broken. (Eccl 4:12) The two pieces are secured by 4" galvanized carriage bolts secured with washer and nut on the other side (single bolt on right). Don't skimp and not get galvanized. This is a non-negotiable. You don’t want water rusting your bolts over time and your structure is only as strong as the bolts holding them. For the screws I went with two ½” thick by 7 inch long galvanized lag screws and washers on each side for attaching the main beams to the trunks. This would ensure that even after going through the two pieces of wood there would be a good 3-4 inches embedded into the hardwood of that solid oak tree.
