Repairs Needed

This outbuilding is built up against the back wall of a property.  On the right hand side a piece of wood is missing making the underneath of the corrugated roof just visible.  The weed growing up the wall is making the most of the gap created and has started to encroach into the outbuilding.  As if that wasn't enough the piece of wood that's still in place has peeling paint and there's mortar missing from the wall.
