Hi,
   Came across this on me travels,another use for a super market trolley park 16' x 16'. Roof still needs to go on yet but I rekon its looking promising,shouldnt have any problems with base rot.  Dave.

I've often thought those "trolley parks" look like they could make greenhouses... well done you for finding one to use.  Might be worth incorporating some roof openings for ventilation... although at present ventilation doesn't appear to be an issue Nice mantis too.

Managed to get roof on no problem now just need to find some corrrugated sheets to cover the sides.Thinking of half greenhouse half Shed.As for roof vents as you will see from new picture already built in though think they will need reducing in size a bit.
