How to Build a Fort With PVC & Outdoor Fabric

Cut the PVC pipe using a saw or PVC cutting rope. Cut 16 pipes 3-foot long, six pipes 3 1/2-foot long, two pipes 5-foot long and six pipes 1 1/2-inches long. There will be leftover PVC.

Assemble the left and right walls on the ground. For each wall, gather seven pieces of 3-foot pipe and lay them out on the ground in the form of two boxes that share a center pole.

Attach one of the outside corners of the box with a 90-degree fitting. This will be the bottom front of the wall. Connect the outside corner directly above it with a "T" fitting.

Move to the center pole joints and connect the bottom edge of the wall with a "T" fitting. Connect the top joint with an "X" fitting.

Connect the back bottom corner with a 3-way "L" fitting and the top corner with a 4-way "LT" fitting. Mirror the fittings on the second wall.

Stand one of the walls upright and have an assistant hold it in place. Insert a 5-foot pipe into the bottom 3-way fitting and another 5-foot pipe into the 4-way fitting. Stand the other wall up and connect it to the other end of the 5-foot poles.

Insert 1 1/2-inch pipes into the open ports on all the fittings along the top of the walls.

Assemble the peaked roof on the ground by gathering six 3 1/2-foot pipes and two 3-foot pipes. The 3-foot pipes will be the supports across the top ridge of the roof and the 3 1/2-foot pipes will make the peak.

Attach a 45-degree elbow to the bottom of all six 3 1/2-foot pipes. Connect two of them with a 3-way "L" fitting, the next two with a 4-way "LT" fitting and the last two with a 3-way "L" fitting. Connect the three peaks by inserting the 3-foot pipes into the open fitting ports.

Connect the roof to the walls by slipping the 45-degree fittings over the 1 1/2-inch pipes. Use an assistant to help carry the roof and line it up properly.

Cut outdoor fabric to size and attach to the fort frame with PVC snap clamps.
