Mezuzah for outdoor shed

It does not look like my previous message got through so forgive me if this is a duplicate. I built a shed in my backyard. It is constructed of resin. The interior is about 7 x 7 feet. The roof is slanted and is about 7 feet high at the apex. There are 2 doors that open- one to the right and one to the left. The doors are flush with the walls.Therefore there is no doorpost on the inside or outside. Does it need a mezuzah? If yes, where do I put it? Thanks.

It does not require a mezuzah. (Correction, see below)

Thank you!

My apologies. It does require a mezuzah if you own the property. If it’s just a rental, then it is a safek and patur.

In terms of where to place the mezuzah,
It would be on the right side of the inner door
