Bin storage unit made of timber, with plants beside.


A bin storage unit helps keep your bin area neat, tidy and looking good. We'll show you how to make one that keeps bins out of sight but easy to access.


1Cut the timber

To make this project easier, we had all of the timber cut to size at Bunnings.

Cut the 70mm x 35mm treated pine to the following lengths:

  • 1020mm x 12
  • 870mm x 8
  • 620mm x 6
  • 1020mm x 6

Next, cut the 90mm x 19mm merbau decking to these lengths:

  • 600mm x 39
  • 1085mm x 6
  • 1240mm x 3
  • 1090mm x 2
  • 890mm x 22
  • 2079mm x 9

Finally, cut the 70mm x 19mm merbau decking to:

  • 1090mm x 2
Timber laid out on a tabletop.

2Build the frames for the dividers and sides

Lay out the timber for the frames, 870mm x 70mm x 35mm x 2 for the top and bottom.

Grab the 1020mm x 3 for the sides and middle. Use the framing gun to fix these together. Measure, mark and fix a 1020mm piece of timber in the centre as an extra stud for support. Countersink with a bugle bit and screw into place with the 75mm screws.

Repeat this step to build three frames.

3Make three back frames

Take the two 620mm x 70mm x 35mm timber pieces and two 1020mm x 70mm x 35mm timber pieces and lay them out. Then fix them together with a framing gun. Countersink with a bugle bit and use the 75mm screws to secure the frame. Repeat the process to build two more frames.

4Clad the end frames

Place the first piece of merbau on the side you want to clad. Measure and mark where you want to drill. Pre-drill the hole with the countersink drill bit and secure the timber with the decking screws. Place 10mm spacers next to the timber and place your second piece of merbau next to it. Secure it using the method above, making sure the screws are in line with each other. Repeat this process until both end frames are clad.

5Assemble the unit

Clear the ground where you're going to place the bin storage unit so that it's level. Next, clamp a back frame to a side frame, making sure the frames are flush. Use the drill bit to countersink and then secure the two with 75mm batten screws. Attach a divider, another back frame, a divider, another back frame, and then the side. Clamp the frames together making sure they are flush, countersink and then screw into place with the 75mm batten screws. Once the unit's assembled, you can attach it to the wall for extra support.

6Attach the cladding to the front

To give the storage unit a nice finish, we're going to attach some cladding to the dividers. Use the two 1090mm x 90mm x 19mm pieces to clad the two end faces and the two 1090mm x 70mm x 19mm pieces to clad the centre dividers. Clamp the timber to the unit. Pre-drill using the countersink bit and then screw into place with the 40mm screws. Evenly space the screws for uniformity. Repeat the process for each front face.

7Attach cladding to the top of the unit

Lay out the merbau decking on top of the unit, making sure it's flush to the top and front of the vertical face cladding you've just installed. Start at the front and work back, evenly spacing the timber with the 10mm spacer so that it fits flush against the back frame. Mark, pre-drill and secure with the 40mm decking screws. Repeat this process until the top of the unit is clad.

8Make the doors

Lay out the door frame with the 2 x 600mm x 90mm x 19mm pieces of timber at the top and the 2 x 1085mm x 90mm x 19mm pieces on the sides. Fix the timber for the top of the frame under the sides. Secure together using the fixing gun and 32mm brads. Before continuing ensure the frame is square by measuring diagonally from corner to corner. The door is square if the distances are the same.

9Attach the cladding to the door

Evenly space the 11 decking boards between the longer sides of the door. Use the nail gun to secure the decking. The ripple side of the decking should face the inside of the storage unit.

10Attach a crossbrace

We're going to attach a crossbrace to give the door extra support. Place a piece of 1240mm x 90mm x 19mm timber diagonally across the door. Mark where it needs to be cut at both ends and use the circular saw to cut it to size and shape. Attach the crossbrace to the door using the nail gun. Repeat this for the 2 other doors.

11Drill holes for the handles

Instead of attaching a handle to open the doors, we're going to drill some holes. To do this, measure and mark 45mm in and 45mm down the top of the door. Clamp the door to the workbench and drill a hole using the 25mm spade bit. Repeat this for the 2 other doors.

12Attach the hinges

Place the hinges where you want them to be, an equal distance from the top and bottom of the door. Mark where the holes need to be drilled. Pre-drill the holes and then attach the hinges to the door. The screws provided may need to be ground off to size. Repeat this for the other doors. The gates are heavy so be sure to use the appropriate size hinge and screws.

13Attach the doors

To attach the door, put it in place, making sure there's an even gap between the door and the frame. Chock the door in place. Mark the position of the hinges. Pre-drill and screw into place using the 10 gauge 50mm screws.  Repeat this for the two other doors.

14Attach a latch

To keep the door closed, we're attaching a latch. To do this, measure and mark where you want the latch to be. Pre-drill the holes and then secure the latch. Measure and mark where the catch will go. Pre-drill the holes and attach the catch. Repeat the process for the other 2 doors.

15Tidy job all done!

And there you have it, a great looking storage unit that'll also keep your bin area neat and tidy.

Health & Safety

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.

When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
