Construct A Wooden Fort Construct A Wooden Fort

What You'll Need
Tape Measure
2x4 wood
2x6 lumber
3/4 -inch plywood
Wood screws
Door Hardware

Take a backyard play area to a whole new level with the addition of a wooden fort. This project will require use of power tools and a variety of construction techniques, but you should not have much of a problem once you familiarize yourself with your plans, materials and the tools you will be using.

Prepare the Ground

Clear the ground that are going to use for your wooden fort. Dig out the sod and prepare a level piece of ground. The size is really up to you, but keep the dimensions of the ground work about a foot more than the actual fort.

Place Posts

Using some 2x4 pieces of lumber, drive two into the ground to form a corner. They should reach to 18" into ground and stick up about 8". Repeat the process at each corner.

Attach Bottom Beam

With the 2x6 lumber, span the distance between corners for the bottom joist. Connect all corners this way. If you are using a span longer than 6 feet, then you will need to add another support in the middle.

Lay Floor

With sheets of ¾-inch plywood, begin laying the floor of the fort. If your floor is more than 4 feet wide by 4 feet long you will need to place middle floor joists to handle the load. Using the wood screws to attach the plywood to the 2x6 joists. Keep placement to about 12 inches.

Build Walls

A fort should  be rustic. To get that feel, cut some of the 2x4s a little shorter than others. Lay them down side by side on the floor. Make sure you cover from one end to the other.

Attach another 2x4 along the width of the boards you laid down, one on the top and the other on the bottom. Add another 2x4 board 4 inches from the bottom and screw to the floor.

Lift Wall

Lift the wall into place and set the wall on the bottom 2x4 that you attached 4 inches from the bottom. Screw into the floor from the top of this 2x4 and from the outside of the wall for added strength. Repeat the last 2 steps until three walls are done.

Build Door

Build a wall as before, but instead of attaching all the boards together, only attach a few on each side. The boards in the middle will be attached together to form the door. Add the door hinges and the latch.


You have a variety of finishes you can use at this point, but at the very least, apply a sealer and stain to protect the structure and the wood from rain, snow and sun.
