How to build a shed - Wednesday, August 27, 2014

Building your own shed gives you a sense of completion unlike purchasing a shed. Although it is going to take more time and you will have to actually build it unlike buying a pre-made shed, if you have the time its a great project. A Shed is built much like a house although a lot easier and money can be saved by making your own shed.


All gardens need space for storage, the family bikes, your tools or the BBQ that needs to stay dry. A shed is a necessity these days. If you require a large shed because you have a lot of storage needs we advise that you do buy a pre-made shed as larger sheds become complicated and take longer in order to create a safe environment for storage.

Check out some great sheds we have on offer that are amazing quality and very competitively priced.

Tools and Materials you will need will depend on size.

Tool wise you will need screwdrivers, saws, screws, spade, step-ladder, Nail gun, hammer and all other tools you think will aid the build.



  • Plenty of Timber (Pressure Treated if you have a larger budget and this saves maintenance)
  • Weed Proof membrane if choosing timber base.
  • Mortor and Concrete as well as bricks to create a concrete base.
  • Paving slabs if you want to choose a slab base.
  • Roofing felt.
  • Support framing and Plywood for floor.

Step 1

Firstly, choose the area in the garden you want to situate your shed and then start to level the ground. Dig out any excess soil and flatten out using a rake, removing all stones for the area until you have a flat surface. From here you have three base choices.

Timber, Concrete or Paving Slap.

Step 2

Once you have your base you can then get timber lengths and attach them to the posts to create the floor layer. This creates a base off the ground and allows ventilation and will stop the floor from touching the soil layer and rotting.

Step 3

Now we have the timber base you can work up from there. Next up is plywood, add plywood to create a floor or alternatively find suitable length planks of timber and screw them down to make a stronger more durable floor. Floor and Base done!

Step 4

Shed walls are easy to make, much similar to the base. Work out lengths that you need, cutting down if needs be, then get to work on creating the walls. The easiest wall is to get a two same length width planks, two height planks and create a square/rectangle. Then using same length planks work out how many you can fit inside your built square/rectangle and screw them down to create a solid wall. Obviously two will have to be made in order to create the shed sides.

Step 5

The back panel is then built exactly the same as the side panels but obviously smaller. You can attach the back panel straight away and this will ten support the two side gables. We then advise that you take sheets of plywood which are then bolted over the frame of the side panels as they act as the walls.


The front panel however will have to have the door for access inside the shed. The easiest way to do this is to create the exact same as the back gable but leave one length of timber out and instead use a small plank just above head height to add horizontally to make keep it stable and secure. This gable can then be added and attached to the side walls which creates the sheds exterior. Again you can then add plywood around the wall, cutting down lengths to perfectly fit the front. 

Step 6 

The roof is then the final section that needs completing. This is where you will need the stepladders to get high enough to fit the planks. The easiest roof to build requires two types of plank lengths. First of all a length that will go from one side to the other and these need to be attached down on the sides and not flat. The second then is a length that fits between the side planks. The easiest way to secure them is to have someone hold the plank straight and then screw them in from under the roof section. This is very similar to the floor joints and the same size can be used obviously. 

Step 7

Once the basis of the roof is formed you can then nail down plywood sections to form the roof layer, if you have added an overhang then this will keep the walls dry. Now that the roof is done its time to add roofing felt. Start from one side and roll out then tack down with a nail gun. Complete the whole roof by leaving space between nails so that when you add the second line you can then attach down too.  Here is a guide on how to felt a roof easily. 

Final Step!

The final thing you then must add is a door. Take two large plywood sections and then two lengths and attach them together with the lengths facing outside. This will be stronger than just a single piece of plywood and then hinge them onto the side of the shed. This will require two people to do so that you can get the door level. Add a bolt to the door and this will keep it shut during night and even allows for a padlock to be added. 

There we have the easiest form of shed to create. If you want to add windows or other features then have a look online and you will be able to find plenty of different designs for you to follow.

We advise you do as much research as possible and be very careful when it comes to attempting your shed.

Again if this seems like a difficult task, save all the hassle and check out sales we have at the moment.
