10 Tips On How to Build a Treehouse

1. Selecting The Perfect Tree

Selecting The Perfect Tree for treehouse

The choice of tree is extremely important as this will hold up the house. If the tree is unstable or weak, there’s a high chance that the treehouse will fall. Using a tree that has a minimum trunk diameter of 12 inches and that has 2-3 main branches that will be able to hold the weight of the house. The tree must also be at least 6-10 feet tall. 

Hardwood trees like oak and maple are good choices for a treehouse. Before building, check for any type of damage on the branches or trunk of the trees and one which has deep roots. During storms, hurricanes or windy conditions, the tree must not sway around too much or be capable of getting uprooted. 

2. Designing The Layouts

Designing The Layouts for treehouse

After surveying the tree, draw up plans and sketches of how you want the treehouse to look. Decide the total length, width and height from the base and of the house itself. After that decide where you’d want to locate the entrance and windows. One interesting design idea would be to add a balcony that would be open to the sky right next to the enclosed treehouse with railings of course! 

It is important to get the correct measurements for all the elements and draw them out. Being clear on this will ensure a smooth sailing construction process. 

3. Choosing The Right Material and Equipment

Choosing The Right Material and Equipment for treehouse

The best part of when you build a treehouse is the fact that all the materials and tools required for it are available a short drive away from your home. 

Here is the list of tools you  will need while building a treehouse: 

  • Timber or Wood
  • Decking Material
  • Screws, nails, washers and hangers
  • Rafter Ties

Ensure that the materials you are using are waterproof and insectproof. The wood should not be susceptible to termite and ant infestations, and must not decay, deform under water absorption from rains. Using engineered wood is a good option when it comes to this.

Along with this, you’ll also need tools like Tape Measures, Markers, hammers, saws, level, wrenches and drills. Additionally, install a stable ladder next to the tree for easy access to upper areas.

4. Building the Platform To Build A Treehouse

Building the Platform To Build A Treehouse

The next step to build a treehouse is to get started on the actual construction. First, the main supports need to be erected with a good foundation underneath. Without this, your treehouse will not be able to stand stably.

After the main supports are up, it’s time to build the main platform. The main platform is the base for the house and so it must be very strong. You can build this platform directly onto the main supports or build it separately and then lift it onto the supports. To do this you need to make a floor joist structure with intersecting planks placed vertically. 

When built like this, the structure will have maximum stability and will prevent bending when weight is put onto it. Make sure you fix the joists tightly with nails and drills.

5. Working On The Horizontals

The next step is to look after the flooring and bracing works. Top the joists with thin planks to form a good base. When mounting the platform onto the supports, you can add diagonal braces underneath that will prevent it from wobbling. 

When you lay the deck make sure you cut out a hole in the shape of the tree in the planks before arranging them neatly on the joists. The planks must be drilled well into the joist structure so none will come out.

6. Building The Enclosure

Building The Enclosure for treehouse

When you build a treehouse, the most important part is the actual enclosed structure. This outer frame must be able to withstand heavy winds and should be able to hold up the roof as well. First, build the frame of the wall using wooden columns and beams attached. 

Once you have a stable frame you can fix planks onto it. Preferably, horizontally fixing them would provide much higher dimensional stability as opposed to vertically. 

7. Ensure Privacy

Ensure Privacy in treehouse

A well-constructed treehouse must have an entrance. Instead of creating a regular door, you can also opt for a hatch opened from below. This type of door would be located on the floor of the treehouse you built and would open up into the room from below. 

If you want to go for a traditional door, make sure you make it tall enough for people to enter and exit. In a traditional door, however, you don’t have to stick to the regular 2m height and can go as low as 1m.

For windows, make sure you have good quality shutters and one that can bring a lot of natural light into space. Depending on the tree, the amount of light coming into the house may get blocked. A window would give a great view of the surrounding branches and leaves.

8. Safety And Access First!

Safety And Access First for treehouse

When you build a treehouse, the biggest danger is falling off of it. Install appropriate railings along the perimeter of the deck. If you have a large window in the treehouse, install grills or a safety ledge to prevent anyone from falling. Additionally, lay mulch on the ground right below the footprint of the treehouse as a precautionary measure to break anyone’s fall in case that were to happen.

Build or install a permanent ladder leading up to the treehouse since using a temporary ladder is inconvenient. Make sure the ladder is stable and fixed correctly to the top platform. Making a ladder with flat steps instead of thin plans is a much safer option.

9. The Roof To Build A Treehouse

Finally, top off the treehouse with a beautiful roof. When it rains or snows, a sloping roof is a perfect way to ensure no water leaks into the house. Flat roofs would also be great depending on one’s preference. An interesting feature to add to a roof would be a skylight! Adding a skylight would not only bring a lot of direct sunlight into the treehouse but also provide some fantastic views of the day and night sky above. You can use wood, tarpaulin or even a metal sheet for the roofing. This will complete the construction of the treehouse.

10. Jazz it Up!

Here are a few of our tips to help you in deciding the ideal decor for your Treehouse

Paint: Painting your treehouse is a great way of brightening it. Painting it together with family would promote bonding, and it’s also a lot of fun.

If you want the treehouse to stand out, use bright colors like red and blue or you could paint it grey, brown, or white to keep it plain and simple.

Lighting Design: It is very possible to install lighting fixtures when you build a tree treehouse! 

As long as you have outlets and a power box to connect it to, you are good to go. Install hanging lights and bulbs on the inside and outside of the house so you can use them during nighttimes. You can also get sockets installed to connect phones, laptops, or even a TV!

Decor Elements: Don’t leave the walls plain, spice them up by hanging photo frames, potted plants, wall hangings, and other fun decor items. 

Multi-Use Furniture Pieces: In a treehouse, since the floor is completely wood, it may get uncomfortable. Introduce some cushions, pillows, bean bags, and small couches into the space to make it more homely. You can also add a cot or bed and make it a bedroom!

Make-shift is a regularly seen concept for Treehouse, and this can be achieved by using multi-utility furniture pieces.
