The very first part when it comes to building a shed floor is to design the shed floor, which is the foundation of the shed. Building a strong shed floor is the key to a stable shed. Designing a shed floor is fun and will definitely put your design skills to the test. A strong shed should be able to bear the weight of several human beings and withstand tough weather condition. Aim for a shed that has tough durability and strength. Before hammering away, be sure to ask the local authorities for permission and information about building guidelines.

The above measurements are just a guide. The size of the floor shed varies and changes to the length of the planks must be done accordingly.

1. Have a Flattened Foundation

Before even laying out the wooden planks, determine the foundation first. No leveling works are needed if it a flat, even-level hard concrete floor. On the other hand, if the shed is to be built on grass, then a bit of digging is needed to make the ground even. Use a hoe blade to make the foundation as flat and even-level as you can. To ensure maximum flatness, drive four wooden stakes at each corner and form an X-shape and check if the entire rope touches the ground.

2. Lay the Skid Foundation

Now it’s time to establish the skid foundation. Make a 6x2 compacted gravel floor to create a stable base. Make sure to spread the gravel evenly. Place two 6x6 skids parallel to each other on the gravel floor. Make sure that entire skids are touching the gravel. This is crucial for a solid foundation. Ensure that each skid is 6 inches away from the length side of the foundation.

3. Connecting the Floor Joists

Now it’s time to join the floor joists together. Use two floor frames and two rim joists to form a rectangular shape. Place this rectangular shape onto the joist using the compacted gravel floor as a guide. Now using a saw, saw and adjust the other floor joist accordingly so that the joist can fit within the rectangular floor frame. Now within the hollow rectangular shape, attach all of the floor joists, making sure that there is even distance between the joists. Be sure to attach the joists to the skids as well.

4. Placing the Board Sheet

Now place the floor board onto the connected joists. When attaching the floor board to the joist, make sure that every joist are nailed firmly to the floorboard. To make sure the floor board is attached firmly to the joist and the floor frame, the nails on each joist should have equal distance of each other.

5. Floor Sheathing

Now it is time to do floor sheathing. The best way to have a beautiful and welcoming floor is to sheathe the area of the floor where the entrance leads into.

Some Additional Tips

  • It is best to use pressure treated lumber for the floor as pressure treated lumber is pest resistant and it does not sag over a long period of time.
  • For safety reasons, be sure to wear goggles and gloves while constructing the floor.
