Sometimes your garden shed is just a temporary structure and you need to have an option of moving it easily. This is where a wooden base for your shed becomes the best option.
The base, once constructed, is fastened into the ground (i.e. grass or soft soil) with metal posts. A wooden base is not suitable for every shed and every ground condition. It is best suited to smaller sheds, as the wooden base does not have the same weight bearing capabilities as a concrete base.
A wooden base would not be suited to conditions where the ground is wet, soft or very uneven. If the ground is wet, the base will rot quickly and your shed may collapse. For wet, uneven or soft ground, concrete pillars or concrete slab are a much better option.
Waltons offers a portable shed base kit – Portabase. The base is available in a variety of sizes, from 6′ x 4′ to 10′ x 8′. The Portabase is made of pressure treated timbers . The Portabase provides inexpensive, hassle free and incredibly easy to assemble shed base solution. Just watch the video below.
A combination of brick and concrete foundations provides the best base for your garden shed. Concrete foundations ensure that your shed is stable, level, less prone to insect infestation and most important – dry.
Unfortunately, concrete foundations are also the most expensive option, they take much longer to build than a wooden base (concrete takes 7 days to cure) and they require some skill, especially with ground preparation and levelling.
Concrete foundations are ideal for any size and any type of shed, whether it is wooden, metal or plastic, providing the ground in your chosen spot is reasonably firm, drains at least moderatly well and is not prone to flooding.
You must also be reasonably sure of your chosen spot. A concrete slab, once build, cannot be moved to another location. You will have to use reasonable force to break it up and remove it or you will end up with an unsightly concrete patch on your lawn.
I have found an excellent video guide prepared by Lafarge Cement. While Lafarge DIY cement is a very good brand of cement that you can certainly use on this project, but you can use any other brand you have. Just prepare the cement mixture according to the quantities and mixing instructions on the packet and you are good to go.
If concrete is used as a base for the retaining wall, this foundation should be at least twice the width of your bricks (8″/20cm) and a minimum of 4″/10cm thick for a small shed and for larger buildings at least 10″/25cm wide and 6″/15cm thick. If you skimp and go much smaller than these dimensions you are wasting your efforts.
Concrete is also used for shed floor and needs to be at least 3″/8cm thick or it will not be strong enough. On spans over 6’/2m aim for at least 4″/10cm thick on firm ground and if the ground is soft or you intend to raise the floor level due to bad ground drainage, you need to use some aggregate.
Two rows of brick are sufficient for smaller sheds, but for larger sheds or where the surrounding ground slopes, is very soft, or drains slowly after rain, three or more rows would be better.

Your concrete foundations are now ready and you can start assembling your shed.

It is not that difficult, even if you’re not a carpenter.
All that is required is for you to follow some quick and easy step by step plans, and you will have it built in no time.

Depending on the type of shed, its purpose and type of ground you are going to build it on, you need to decide on the best foundations for your garden shed. We have a great guide on “Garden sheds – How to choose the right foundations”.
Purchase the materials you will need as outlined in your plan. It’s a good idea to have everything at hand so you don’t have to keep running out for supplies once you start building your shed. If you are looking for a timber merchant or some other tool or material supplier in your area, you can have a look at our Online Directory . We list suppliers in many parts of the UK and Ireland, and most of them will deliver directly to your doorsteps.
We frequenly publish Special Deals on shed materials, ready-made garden sheds, shed plans, tools, books and shed accessories, so if you are planning to build your own garden shed or you are a DIY enthusiast, follow that link as well. Your local store may not always be the cheapest, so it is worth to compare prices and suppliers.
Now you are ready to start. Level your ground and prepare to lay the foundation. You would have already decided whether you are going to have a wood plank floor or concrete slab type. Check our article on “How to prepare the ground and lay the shed foundations” for step-by-step instructions. We even include a handy video.
Construct the floor according to the instructions included with your shed plans. Next come the side walls. Put your materials aside that you are going to use for this. It is better to construct the walls on the ground then lift them into position once they are together. Just follow your guide for the how to instructions.
Now its time to start the roof. You will need to build your trusses. So construct one and then use it as a template for the rest. Once again follow your guide on how to build the trusses.
Your storage shed should now be taking on some shape. Its time to build the end walls. How you do this will depend on the instructions included with your plans. Be sure to stay with your original plans. Changing horses mid-stream is never a good idea.
Now you are getting down to the final steps. The trim is just as important as the rest of your structure. It is what gives it that finished look so don’t scrimp here.
Your last two steps are applying the shingles for the roof, then treating the wood. The wood must have some type of protective coating on it to protect it from the elements and rotting. This can be varnish, stains or paints whatever is your preference.
You’re done! All that’s left is to sit back and admire your creation. You got yourself a great looking garden shed at a fraction of a price charged by the garden centres.
