Type of Food
Before designing a concession stand, decide what type of products you will sell. Stands that sell only packaged foods, such as candy bars and bottled water, do not require electricity and running water. But if you'll sell hamburgers and fountain drinks, the stand will need electricity, running water, proper ventilation and proper plumbing.
Decide whether the concession stand will be fixed or mobile. Fixed concession stands are ideal for venues with regular activities, such as parks, schools and athletic fields. Mobile concession stands can be built on trailers and transported to events such as carnivals and festivals.
Windows and Staff
Estimate how many employees will work at the concession stand. This will help when designing the stand's interior layout. Decide how customers should approach the stand. Should there be multiple lines or a single line? If you'll have multiple lines, decide whether all items will be available in each line or if you want a separate line for each items (for example, one line for soda, one line for popcorn).
Before building, consult the local health authority and acquire any building permits that are required. A food service license may be required as well, depending on the type of food being served, and many health codes require that certain types of equipment and food be kept separate. You will have to accommodate these regulations in any building design.
