Planning and preparation
  • We are going to show you how to build custom outdoor storage, step by step.
  • It provides the perfect additional storage for boots, bikes and bins, protecting them from the weather, keeping them locked away securely and tucking away anything unsightly.
  • This custom outdoor storage is built completely to the dimensions of whatever you want to store. So, you get complete freedom when it comes to size and design.
  • All of the materials used are available from Wickes.
  • It should take a DIYer with moderate skill approximately two to three days to build.
Doing it right
  • Make sure to measure the available space and consider access, sightlines and location.
  • Choose timber that can stand up to the elements - it’s going to be exposed to rain and wind outside during the colder months.
  • When working with exterior paint and brushes, work slowly to apply thin and even coats until you have your desired coverage.
Staying safe
  • Always make sure that your chop saw is unplugged while you’re setting it up or changing accessories, to ensure your safety.
  • Keeping the plug in-sight acts as a visual reminder to prevent accidents and hazards.
  • For extra safety when using power tools and painting, be sure to wear protective equipment, including your ear defenders, goggles and a dust mask. 

Measuring up

View instructions
Measuring wheelie bin

Measure the depth, height and width of the bin or bins you plan to store in your custom outdoor storage.

Measuring bike

Measure the height and length of your bike, or consider how much space you’d require if you plan to store multiple bikes.

Make sure to give yourself some extra space on all of your measurements. This helps you make sure the storage area isn’t too tight and makes it easier to accommodate your items.

Measuring boot rack

If including your boot stand, make sure to measure its depth, height and width as well.

Deciding your design

View instructions
We built the entire store in our workshop, but it’s designed to be moved to your desired location before the final construction takes place. This allows you to easily transport it in pieces, rather than as a whole unit.
Sketching design
Take plenty of time to create a design that suits the space you’re working in.

This build guide will give you the principles of building the store, but the project itself is completely bespoke.

Set square
Our design includes a sloping roof- if you wish to have a sloping roof, you’ll need to calculate the pitch of your roof based on your measurements.
This angle is key when constructing your frame, as it provides a reference for all of your angled cuts.

Cutting timber and calculating the roof angle

View instructions
Circular saw

Once you have your measurements and your design, cut your timber and cladding to size.

Make sure you support the ends of longer lengths when cutting them.

Set square
There are a couple of methods you could use to mark the angle on your lengths. We opted for a digital adjustable square .
Measuring circular saw
With your digital adjustable square, loosen the saw bed and change the angle to match before locking it into the new positio n.
Cutting with circular saw 7

Now you can make your angled cuts according to your measurements.

Framing up

View instructions
Sanding frames 1
Smooth out any rough edges by going over any feathered cuts with sandpaper.

Dry lay your frames one at a time, placing them in position.

Building frames 13
Drill pilot holes for your butt joints, then affix them with screws .
Building frames 13

Butt join the frames together to form the roof.


View instructions
We recommend doing this on a firm surface, such as an even floor.
Check that everything is straight and square before you start nailing the cladding into the frame.
Cladding frames 6
Starting from the bottom, nail in the cladding across the fram e.

We used tongue and groove, but it’s up to you when it comes to the cladding you use.

Cladding frames 4
Once you get to the end, you’ll need to use your judgement to work out the best places for your final nails .
Sawing wood

Lift the frame onto your workbench and trim away any overhang.

Sandung frames

Flip the frame over and go over it with sandpaper, before repeating these steps for all remaining sides.

Adding diagonal frame

Building frames 9

Assuming your workbench is square, clamp your frame to the workbench in one corner and use it to make sure the corners are sitting at 90°.

Measuring frames
Lay the diagonal piece across your frame and mark the angles.
Cutting with circular saw
Angle your chop saw accordingly and cut it to size.
Clamp and drill
Then clamp and screw it into plac e.

Putting it together

View instructions

Clamp your fence posts into position on the cladded side panel.

Assembling structure 5
Screw them together from the inside .
Creating boots section

Build up the store panel-by-panel using the fence posts, then dry lay each roof panel on top of the structure.

Adding the roof

View instructions

Check that your roof panels are straight and aligned.

Clamping the structure 2

Clamp them into position.

Drilling into the structure 6

Screw them in from underneath.

Fixing roofing 5

Start on the lower end and lay your roofing tiles so that they’re overlapping one another.

Fixing roofing 8

We used corrugated roof tiles as they’re stronger, which is essential to support the weight of the roof garden.

We calculated this so that the frames create cross-beams, which can be screwed into.

Leave an overhang at the lower end so that water can easily run off.

Screw roofing to structure
Affix the roof with Onduline fixings.

By overlapping the roof tiles and aligning them with the cross-beams, it allows you to fix through both materials directly into the beam below.

Fixing handles to the doors

View instructions
Fixing hinges

Screw the hinges into the frame.

Fitting handles

Fit your handles in the desired spots.

Check that everything is screwed into the solid frame structure.

Adding the fascia

View instructions

It helps to have a second person for this step, but it can be done alone.

Fixing facade 2
Drive two small screws into the front of the fascia to hold it in place .
Adding joists
Then screw it from the inside for a neater finis h.

If you used temporary screws, filling the holes gives it a more seamless look.

Fixing facade 5
Screw in the end panel.

Adding the mesh

Marking meshing

Measure the width of your roof before cutting two thin pieces of timber and your mesh to size.
Affixing lining

Screw the framework timber into place, then fit your mesh on the roo f.

Sealing the roof

Sealing roof

Seal the edges of your roof with a black flexible gutter sealant.

Work your way around the frame until it’s complete.

Planting on the roof

View instructions

Put down a layer of 10mm gravel.

Then put down a layer of your chosen compost.

Plant your chosen plants.

Finishing outdoor storage 9
Hang your doors and fit any latches, bolts or locks to ensure your custom outdoor storage is secure.
There you have it, your very own custom-built outdoor storage .
