Building a treehouse for one tree
If you have only one tree, you are limited to the choice of treehouse design. It has to surround the tree trunk. The floor is held by support beams that radiate from the tree trunk. The radiating supports use four or six beams.
The beams radiate directly out from the tree. They need steel brackets to attach them to the tree. You are allowed to choose another method that does not require brackets. It uses beams attached in a spiral pattern.
For an attachment, use the bolts. However, bolts have their disadvantages. More of the beam is in contact with the tree, causing more restriction to its growth in the future. As you increase the number of support beams, the effect also increases.
However, there is a standard limit of the beams used on the treehouse. Use a maximum of six beams since the space becomes limited as the support beams crowd together. Attach the beams at right angles to the trunk. Support beams are more like spokes.
They need support from knee braces underneath and substituted with cables or braces above. That keeps them in tension. They work the same way with the upside-down knee braces with the treehouse suspended underneath.
When you choose to use cables, go for a steel cable. Secure the cable to the end of each spoke. It has to reach a point higher up the tree, fastened to an eyebolt. The steel cable can get in the way of the superstructure of the treehouse but bear in mind that alterations increase the problem. Each spoke can be lengthened, and the cables sent up at a steeper angle to clear the walls and roof. You need a scale drawing to calculate the angles and lengths you need.
When choosing a treehouse design, look for one that does not take more time. Building around a tree lends you a circular structure. However, creating a curve in a wooden form requires more time than if the treehouse runs together at right angles.
Hexagonal and octagonal treehouses are also beautiful, but they revolve around geometry. That slows down the building process. You can choose to break away from the cube look. It starts with planning your treehouse as a collection of boxes that intersect. That way, you produce more shapes and give the treehouse a unique internal space.
You have the freedom to express your creativity. You cannot stick to one shape. There are times when the treehouse can be offset on one side of the trunk. That is if the supporting tree is large enough to allow the floor area to be a useful space.
It results in a large load on one side of the tree. That is why you need to balance the tree out on the other side of the trunk if it is not big enough. Use a deck or simple landing for a staircase to balance the weight and appearance of the house.
How do you build a freestanding treehouse?
- Sink four sturdy posts deep into the ground where your treehouse will sit.
- Secure the posts with concrete.
- Attach a wooden base or platform of your choice to the posts.
- Start building your treehouse on top of the platform.
- Add accessories of your choice, such as stairs or fencing.
A freestanding treehouse is made of a tree that does not come attached to any tree or branch. It stands on its own. Use pressure-treated posts to support the tree structure. They should be buried deep enough for full support.
Round telephone poles are also ideal because they last longer underground. Sinking your posts into the ground gives a better base for your treehouse to sit on. Secure the poles with concrete. Attach a wooden platform to the posts. You can then build the treehouse on top of the wooden platform and add stairs or a pulley.
How do you build a treehouse without harming the tree?
Maintain minimal penetration
Nails or bolts create a wound that causes damage to the tree. It is your responsibility that your treehouse does not kill the tree. To achieve this, use the care and equipment. That way, get full recovery and heal the damaged areas.
Anything you stick in the tree should not rust. Only use galvanized nails or bolts. Make them few and use high load-bearing structures. Reduce the number of open sores to minimize direct entry points to infections.
Reduce load on the tree
Do not overload the tree with ropes and pulleys. They cause unnecessary stress on the tree over time. It becomes malformed and quickly dies. Any harm to the treehouse affects its growth. That is why you should minimize any potential damage to the treehouse structure or eliminate it. That is by using TABs(Tree Attachment Bolts). They are meant to be high load-bearing and cause minimal damage to trees.
Use Tree Attachment Bolts
These bear loads of between 8,000-13,000 pounds. They withstand more weight, by reducing the number of foreign objects embedded in the tree. TABS are of the stem, boss, perch, and tab Nut.
Use TABs of the correct size. The TAB ensures safe load-bearing across the attachment points. If you get it wrong, you damage the tree and your treehouse.
How do you attach a treehouse to a tree?
Use eye-bolts to attach a treehouse to a tree. Attach them on the outside of the floor. That is near any limbs and wrap the rope around the branches four times. Let them go through the bolts and knot securely.
Use a minimum of two bolts under the floor to keep the base of the treehouse attached. Suspend the platform with steel ropes.
What to know before building a treehouse?
- Your neighbors should be comfortable with having a treehouse close.
- Design of your choice.
- The rules and regulations of your area.
- Advice and tips for building.
- Wood age.
- Environmental impact.
How deep should a treehouse post be?
The posts should be 36inch deep to avoid using cross beams for support. For large or heavy structures, incorporate some cross bracing to ensure structural integrity. Position the posts accurately using a temporary framework. Pour concrete around the post in the hole.
