Choose the styles and overall width x length x height that you want for the base unit.  Then choose the additional options you would like to add.  Each item is priced separately to assure that each customer has all the information, options and tools necessary to make the best decision for their storage and protection needs while meeting their budget as well.  Once the base unit is selected and installed other options can be added at a later date such as sides, ends, gables, doors, and windows. Units can have additional length added but the most important decision you have to make is choosing the width and height everything else can be added to following the initial installation (for a trip fee plus the current cost of the options).  Below are the unit pricing (subject to change until deposit is secured and contract is signed by customer).
