Choosing The Right Base

Any garden building requires a flat, levelled and strong foundation. This will help protect your shed from deteriorating and will prolong its life.

Where should I place my shed?

The size of the shed will determine where you should place it and how big the base should be. Before purchasing a shed, remember to check that you have an appropriate space for the product, check all dimensions and make sure that there are no obstructions. When choosing where to place your shed you should keep in mind that tree roots can grow larger causing uneven ground consequently damaging your shed. Placing a shed near a tree can also lead to problems during winter; bad weather conditions can cause parts of the tree to fall and damage your shed.

When choosing where to place your shed you need to consider its maximum height and dimensions.

What can I build my base from?

There are many options when it comes to choosing a base for your garden building. There are a few things to consider before purchasing the right materials for your garden. Here are a few factors you might want to consider before you make a final decision. If you rent a home you might want to choose a non-permanent base. You might need to consider what the weather is like where you live. If you get a lot of rain or heavy weather you might want to choose a material that is strong enough to withstand it.
