How to Build a Garden Shed

How to build your own garden shed

Building a wooden shed isn’t too difficult with all the right tools. Ensure you follow all safety measures to prevent accidents from occurring, the task requires two people so please make sure you have somebody to assist you throughout.

You will need the following:

  • Shed base
  • Step ladder
  • Power rigger gloves
  • Safety goggles
  • Nails and screws
  • Forged claw hammer
  • Power drill
  • Open tape
  • Spirit level
  • Craft knife
  • Varnish brush
  • Sealant gun

The shed base: The most important part of the shed. The base needs to be strong and level and should be slightly smaller than the external dimensions of the shed.

Assemble the shed floor:

Lay out the joists under the floor sheet.

Fix the first joists under the long outer edges.

Put the remaining joists evenly between them and they can then be fixed in place


Putting up the walls:

Mark the center point of the shed floor and of each wall at the bottom edge.

Stand the gable end on the base and line up the center marks.

Don’t fix the wall panels until the roof has been fitted.

With your assistant supporting the panel, check that it is vertical with the spirit level.

Next, fix the side panel to the gable end panel with three countersunk screws.

Fix the second side panel and the door panel in the same way.

Fit the roof:

Fix the roof support bar.

Nail the roof panels in place. Ensuring that there is an equal and parallel overlap at either end.

After rolling the roof felt, secure the felt with clout headed felt tacks at 100m intervals.

Apply mastic sealant with the sealant gun to the outer corners, fixing the corner trims with 300mm nails.

Nail the fascias and the finials with 40mm nails through the felt.

Fix the windows:

Put the plastic sills between the window frames.

Put the window cover strip, place the glazing sheets.

Fix the window beading with 25mm nails from inside the shed.

Fix the wall panels to the floor with 50mm screws after ensuring the center marks and the alignment with the joists.

Your new self-made garden shed is complete and ready to be enjoyed! Don’t forget to share your DIY photos with us on Facebook and Twitter.
