This step by step diy woodworking project is about outdoor fort plans. I have designed this super simple fort so you can build one in the weekend, using basic materials and tools. My fort plans feature a ladder and a nice slide, so the kids will be entertained and have multiple choices to play. Make sure you smooth the exposed sharp edges by using a router or a sander.
There are many fort plans you can choose from, so make sure you take a look over the alternatives before starting the actual construction project. Invest in high quality and weather resistant lumber, such as cedar, pine or redwood. Always take accurate measurements and use a professional saw when building the components, in order to get the job done properly from the very beginning. See all my Premium Plans HERE.

Tree Fort Plans
The first step of the project is to build the base frame for the outdoor fort. Cut the components as shown in the plans, using 2×4 lumber. Lay the components on a level surface and align the edges flush. Make sure the corners are square, drill pilot holes and insert 2 1/2″ screws.
The next step of the project is to build the floor frame. Use the same techniques described above, but use 2×6 boards.
Cut the legs for the outdoor fort from 2x4s. Attach the legs to the frames. Plumb the legs with a spirit level and make sure the frames are perfectly horizontal. Drill pilot holes through the legs and insert 2 1/2″ screws. Use 2 screws for each joint.
Use 1×6 boards for the floor of the fort. Cut the boards at 24″ and at 72″. Use a piece of 1/2″ plywood to create even gaps. Drill pilot holes and insert 1 5/8″ screws to lock the boards to the frame of the floor.
Use 2×4 lumber for the top frame. Drill pilot holes and insert 2 1/2″ screws to assemble the frame.
Fit the top frame to the outdoor fort and align the edges. Drill pilot holes through the legs and insert 2 1/2″ screws to lock the frame into place tightly.
Use 2×4 lumber for the rafters. Make the angle cuts at both ends, as shown in the diagram.
Lay the rafters on a level surface and fit the 1/2″ plywood gussets. Align the edges and insert 1 5/8″ screws to assemble the trusses.
Fit the trusses to the top of the outdoor fort and place them equally spaced. Use rafter ties to lock the trusses into place tightly. Plumb the trusses before attaching the trusses.
Use 1×6 boards for the roofing. Start attaching the boards from the bottom up to the top, making sure they overlap for at least 1/2″. Use 1 5/8″ screws to secure the boards to the trusses.
Use 2×4 lumber for the railings supports. Drill pilot holes and insert 2 1/2″ screws to lock them to the vertical posts. You can adjust the size of the railings to suit your needs.
Fit the rail supports to the other sides of the fort.
Use 1x2s for the balusters. You can adjust the space between the balusters. Drill pilot holes and insert 1 5/8″ screws to lock them to the supports.
Fit the balusters to the other side of the bort.
Now it’s time to build the ladder for the fort. Use 2×4 lumber for the supports. Use a miter saw to make the angle cuts, as shown in the plans.
Assemble the ladder by fitting the horizontal steps. Drill pilot holes through the supports and insert 2 1/2″ screws into the steps.
Fit the ladder to the fort, as shown in the diagram. Drill pilot holes and insert 2 1/2″ screws to secure it into place.
Attach the slide to the outdoor fort, as shown in the diagram.
Last but not least, you need to take care of the finishing touches. Fill the holes with wood putty and smooth the surface with 120-220 grit sandpaper.
Top Tip: Apply several coats of stain or paint to the components, in order to protect them from decay. Choose vivid colors in order to create a nice appearance. Lots of project plans for kids HERE.
