There are several steps to take before you can build a backyard treehouse. Before you start, you must determine the species of tree you want to plant. You can find the list on the USDA plant site. Before deciding on a species, make sure to check its health status. Some species of trees are threatened or endangered, so be sure to check this list first. Also, check which tree can drop heavy branches, such as cottonwoods or alders. Your local horticulture extension agent can also give you advice.

Cost of Building a Backyard Treehouse

There are several ways to cut the cost of building a backyard treehouse. One great way to save money is to use the free materials you find in your yard. You can find wood for free at your local lumber yard or construction site, and you can use recycled fence posts to create the sides of your treehouse. A treehouse needs a way to get in and out, and you can easily build a rope ladder to save even more money.

The cost of building a backyard treehouse can be pretty high. The materials and labor for the project are the most significant expenses. The cost of building a treehouse depends on the size, type of wood, the exterior and interior finish, and the number of accessories. The cost of the materials and labor for the project can range from $1,200 to $2,000, and the cost of the tree may be more than this.

Build a Backyard Treehouse

Considering building a treehouse in your yard, it is important to know the cost before starting the project. Costs can add up quickly depending on the size and complexity of the project. In addition to materials, the cost of building a treehouse can also depend on the number of permits required, the type of tree, and the location. You’ll also have to consider the cost of maintenance, such as pest control, painting, and repairs.

Aside from tools, you’ll also need to consult an arborist before choosing the right tree for your project. You should also consult your local building codes and check with your homeowner’s insurance agent to determine if your treehouse project is covered under their policy. This way, you can get the best value for your money and ensure the safety of everyone involved. If you decide to hire professionals to build the treehouse, make sure to choose a professional that is familiar with treehouse construction.

A treehouse can be fully functional, with multiple bedrooms and modern amenities. A modern treehouse can feature a full kitchen, a kitchenette, a microwave, and a fridge. Depending on its size, you might have to add additional posts or a roof if you plan to build a larger treehouse. And remember that you might have to do some plumbing work in the trees, which can be expensive.


To build a backyard treehouse, you must build a basic frame. This frame should be constructed of cinder blocks spaced according to your plans. Next, nail four 4×4 wood posts into the cinder blocks. These posts should be tall enough to serve as corner posts for the treehouse’s railing. After the posts have been attached, cut 2×8 planks and secure them to each other with framing nails. Use three-inch nails to attach the floor frame to the four posts. This frame will support the floor of the treehouse.

The wood used to construct your treehouse should be a non-toxic material. Cedar and oak are good choices. These materials are durable, as they’ll withstand the weather. However, hardwoods like oak will add weight to the structure. Another good material for the treehouse’s walls is plywood. Whether you use wood or plywood, you’ll need to decide on the materials that will work best for your backyard treehouse.

Next, you need to build the roof of your treehouse. You can choose to use a tarp or other material, but make sure that it’s sturdy enough to support the weight of your treehouse. You should place one hook eight feet up from the platform and one in between. Afterward, you should slip the tarp overhead. You will then need four outriggers to attach to the corners of the railing.

Whether you’re building a treehouse for children or adults, you can choose a material that suits your tastes. You can choose a simple wooden design or more intricate and detailed woodwork. A wooden treehouse can have three walls and a sturdy plastic roof. You can also opt for a camping tent-style treehouse based on an A-frame with a 60-degree slope. You can even build a treehouse out of an old fence.

Aside from plywood, you can also choose timber sheets for your treehouse. Although plywood is cheaper, it will not provide the same level of protection and rigidity as a more expensive option. Once you have the base, you can start building the walls and roof. Be sure to include a roof deck and railings. You can also use old fencing or timber frames to build the treehouse walls and floor.


A backyard treehouse is a fun activity for kids. Unlike a fort or a bunker, a treehouse is built in the trees. You can build a treehouse with a slide or a zip line, or you can build one with a rock climbing wall. Whatever your children’s imagination, there are many options for backyard treehouses. Treehouses can be designed to look like a pirate ship, princess palace, or spaceship, and you can use wood from the tree to build the walls and floors. You can even add rustic railings to a treehouse.

You can incorporate glazing into the design if you want to give your kids a place to relax. Glazing your treehouse with windows and patio doors can let in plenty of natural light and provide a stunning backdrop for the interior design. You can incorporate outdoor furniture into your backyard treehouse design, including a deck area. The sky is the limit when it comes to treehouse design. Make sure to use wood that will last for decades.

There are a variety of treehouse designs that are easy to build. You can follow the instructions in the plans and use a simple design to create a fun structure for the kids. Make sure you consider the materials you already have and use those accordingly. Depending on where you live, you may not need to add additional insulation. If you choose to do so, you should ensure that it’s recycled.

Consider the size and layout of the treehouse. For example, if you are planning to have guests, you may not want to build a house at the top of a tree, and your guests might find it uncomfortable. You can also place an electric or wood-burning stove inside the treehouse. Another option is to install solar panels on the roof. A small kitchen can work well in a treehouse design.

Another design option is to build a treehouse suspended in the trees. This will give your treehouse character and blend in with the surrounding nature. Another way to add character to your backyard treehouse design is to install a wooden sliding door between the trees. If you don’t want to use the sliding door, you can always close it and create a dry room under the roof. You can even use a suspended wooden terrace.


There are two main methods of building a treehouse. The first one uses a frame made of beams or TABs. The second uses decking or plywood. This method is recommended for novices, since it’s easier to visualize the location of nailing and drainage holes before installing the decking. Using a level, determine the exact height of the floor and head, and mark the locations of these holes. Then, attach the strips of wood to the frame.

Although most treehouses are constructed using scrap materials, you should choose higher-grade materials. Treated wood is best for this project because it lasts for about 10 years. Reclaimed materials are also good options. However, they may need some modifications and sealing. You can find some of the materials you need at a home improvement center. Besides scrap wood, you will need to get rustproof screws, metal fasteners, and other hardware.

Start by building the roof and floor of the treehouse. You can use exterior plywood for the walls. Just make sure to leave about 1/4 inch-inch of space between each joist. Once these are done, you can add the rafters to the frame. Make sure that each rafter reaches the top plate of the walls. If the treehouse is in a climate-controlled environment, you should use flooring paper.

Once you’ve built the frame, the next step is the roof. The roof should be sturdy but also support the treehouse’s weight. Alternatively, you can purchase a ready-made roof and build it. Just make sure that it has proper supports so that it won’t cause damage to the tree. You’ll also want to consider adding a porch railing if you’d like to use one.

If you’re a beginner, you can also build a backyard treehouse without using the trees. There are several different designs to choose from, ranging from simple to the complicated. Whatever your skill level is, the process of building a backyard treehouse is meant to be fun and rewarding for everyone involved. And, the best part about it is that it won’t cost you much money. You can get a great deal by salvaging materials from nearby companies. The nearest electric cooperative may even have scrap poles lying around.
