Storing items is a great short or long term solution to solving all sorts of issues, where having less clutter and clobber around would be of great benefit. All sorts of items can be stored from boxes of trifling objects that need to be put to one side temporarily, to antiques, jewellery and vehicles.
You might want to store items away when going through the house move process, first of all to make space to prepare the house for viewings, and then to keep the new house relatively empty whilst decorating without falling over piles of boxes all the time. The option can also extend to more temporarily periods when needing more space at home, such as if a lot of guests are staying.
Sometimes circumstances mean that we have to be away out of town for a long time, and again this is where self storage facilities come into their own, with options for those who might be going elsewhere for a while but will need to come back to regular life and their belongings later on. Perfect for long holidays, and a better option than passing on your clutter to another family member.
These are just the most obvious ideas - many people have been far more daring and creative in their application of self storage. Just think what you could do with an extra piece of empty space.
