You already have nearby stairs. I picture making those two decks level.

Do you need to access shed from the current deck area?

That's a pretty small shed unless some is missing from the picture. Could it be lifted to accommodate the new doors, add a stone foundation, and create a new floor?

Can you post more pictures?

Tie in the steps to the current ones on the side. Just extend to the new door.

Wide steps to cover mulch and maybe some of the pavers perhaps with a step down to the shed door. However, will be very busy in that corner.
