How to Build a Shed

1
Prepare Your Area
A man lays a concrete foundation for a DIY shed.

One of the most important things you need to know about how to build a shed is creating the right foundation. Find or make a level space in your yard that has good water drainage. There are several foundation options: 


  • Concrete floor – Pour a concrete slab that’s a little bigger than your shed’s base. Let the slab dry completely based on the concrete mix manufacturer's directions. 
  • Ground - Use a standard level to make sure your ground is flat. If your yard has a slope, level it and use a tamp to even out and compact the soil. Spread gravel evenly across the area to keep the soil from eroding and becoming waterlogged. 
  • Wooden deck or platform – See how to build a ground level deck to install your shed on here

Unpack the Shed Kit
A man unpacks the pieces of a DIY shed.
  • Unpack your DIY shed kit. 
  • Check the contents to make sure you have all the pieces listed in the manufacturer's instructions 


Tip: Panels are typically stamped with identification on their interior side that shows you where they go.

3
Assemble the Floor
A man assembles the floor of a DIY shed.
  • Connect two floor panels according to the instructions to form the back portion of the floor
  • Connect two panels to form the middle portion of the floor, then connect to the back portion by tilting at a 45-degree angle 
  • Repeat this for the front two panels 
  • Anchor the floor to the foundation using screws per manufacturer's instructions


Tip: Avoid assembly errors later by referring to the manufacturer's instructions often while building your shed.

4
Assemble the First Wall
A man assembles a wall in a DIY shed.
  • Identify which panels make up the first wall
  • Starting at the front of the shed, install the first panel at the front edge of one side 
  • Anchor the first panel to the floor using the included plastic screws 
  • Slide the second wall panel into position alongside the first and snap into place
  • Screw into the floor with the plastic screws
  • Repeat with the third wall panel to complete the first wall 
  • Hold the first complete wall in position until the first corner is installed


Tip: Many of the steps require assistance lifting and holding parts steady, so have a friend or two help. 

5
Assemble the First Corner
A man locks in the corner of a DIY shed.
  • Anchor the first back panel to the floor assembly using screws, then stabilize the corner using corner locks
  • Align the corner inserts with the corner holes and pull to lock into position


Tip: Hold the first complete wall in position until the first corner is installed. 

6
Assemble the Rest of the Shed
A man installs the wall of a DIY shed.
  • Continue installing wall panels
  • Repeat the process of clicking each panel into the previous panel, then screwing into the floor to secure 
  • Remember to add corner locks at each corner
7
Install Shed Supports
A man screws in the shelf support for a DIY shed.
  • Attach gutter wall connectors to the top of each support to secure the roof assembly to the tops of the wall panels 
  • Screw the shelf supports in at the pre-drilled holes along the side shed walls 
  • Install the supports loosely on both sides of the two window panels
  • For the three shelf supports on the back wall, attach the left and right supports in the same way you did the side supports
  • Before installing the center support, attach the extender so it rises above the back wall
8
Assemble the Roof Frame
Two men working on the trusses for the shed's roof.
  • The roof frame will consist of two joined trusses
  • Assemble trusses according to manufacturer’s instructions 
  • Tie trusses together with roof supports, creating a single one-piece frame
  • Attach the skylight onto the top of the frame 
  • Place the roof frame into position on top of the side walls
  • Have someone help hold the frame in place while you fasten the roof frame to the gutter connectors using hex bolts
9
Attach the Gables
Man attaching gables to the side of the shed.
  • Snap all the pieces together to make each gable
  • Slide the back wall center extender through the hole in the gable and rest the gable on the wall
  • Snap the front gable to the top of the two wall panels on each side of the door opening
  • Snap the skylight over the peaks of both gables
  • Secure the gables to the wall with plastic screws 
  • Stabilize the structure by installing additional support beams, a horizontal support for the front gable plus right and left roof supports


Tip: If the pieces are too snug to slide together easily, spray with a little soapy water to lubricate them.

10
Make the Shed's Roof
The last of the roof panels are added to a DIY shed.
  • Each of the six roof panels will slide into the tracks on the roof supports and snap into position on the skylight
  • Align the snaps on each panel before applying pressure 
  • Repeat with each roof panel to complete the roof assembly
11
Add the Door
A finished DIY shed resting on a concrete slab.
  • Snap the three hinges into place and secure with screws 
  • Align the handles on each door and connect them with screws
  • Attach the doors to the shed frame with two screws at each hinge 
  • Attach the door latches to the interior edges at the top and bottom of each door
  • Test the doors to ensure they easily open and latch closed
