Old shed for Firewood (Crown Wood RG12)

I have an old 8X6ft wooden shed...Still standing but barely. NO GOOD AS A SHED NOW. ITS NEVER HAD THE BROWN DISCONTINUED STAIN ON. I WAS PAINTED WITH NORMAL GREEN GARDEN PAINT.
JUST WONDERED IF ANYONE WHO HAS A WOOD BURNER AND COULD USE IT FOR THE COMING WINTER,
