Advice needed for an umcoming small project...maybe.

Is the bottom of the cross beam on the left door above the floor of the shed or is it below? The two cross beams appear to be at different heights. You probably don't want to mess with the cross beams unless you want to rebuild the entire door. Which door is the center beam attached to? When the doors are closed, do they hit/rest against the raised floor or is there some room between the raised floor and the doors? Both doors appear to be missing pieces at the bottom -- if you haven't had water seepage by now, trimming them probably could be done. I would keep the trimmed height below the floor height.

It really depends on how much work on it you want to do and what tools you have at your disposal.
