Getting an outdoor storage box does not seem like rocket science, but still, there are some factors you need to consider to make the best purchasing decision possible, such as:
Weatherproofing
This will partly depend on the area in which you live, although almost every area is susceptible to bad weather. The main thing to look out for when buying a wooden box is whether or not it is waterproof. Wooden boxes are generally not very waterproof unless they are painted and coated with varnish, but this is something that you can easily do yourself if you feel it's necessary. Another option is to buy a waterproof cover that you can put over the box – this means you don't have to alter the box itself in any way, but rather just protect it from any wild weather.
The amount of storage
Different people need different levels of storage within their gardens, so you should consider specifically how large a box you need. In order to answer this, you'll need to consider what items you actually want to store in the box. If you don't know what you're going to store yet, take a look at the size of your garden and choose something which is an appropriate size e.g. not so large that it takes up most of your garden but not so small that you can't really fit anything in it. Many people use storage boxes outside for keeping their gardening equipment, but the primary purpose is to store wood that you can use for a fire, whether outdoors or indoors.
Open or closed design
One of the design aspects that you should think about is whether you want it to be open or closed. If you are buying a cover to protect it or you generally have good weather where you live, consider an open design which enables you to easily access the wood whenever you need it without having to unlock the box or open any doors. You should ensure that your garden is safe and secure and that nobody is able to easy get into the box and take the wood.
Space efficiency
The shape of your wooden box is key to saving the maximum amount of space possible. A taller box will still give you enough space to store long pieces of wood while saving the space in your garden so that you have room for other furniture and garden items. For those with a smaller garden, it's definitely possible to buy a storage box for your firewood which fits comfortably in the garden and doesn't take up much room. You can also buy foldable and stackable boxes which is another great way to be effective with the space that you have. As long as the firewood is cut into long pieces and stored upright, a tall outdoor storage box could be ideal for you.
