No building experience necessary!
Upcycled mini pantries work great, and they’re green!
Here are some ideas.

See Little Free Library’s has a guide for turning newspaper boxes in to an LFL (or P).

If you prefer the look of a built mini pantry, reach out to local carpenters/artists and offer promotional signage in return for their work. High school woodshop classes, scout troops, 4-H clubs, and other service-oriented civic groups might also be willing to take on a build.
