Basicly it wont be big enough for a horse to turn around it. So IF you go ahead then you MUST have the opening on the 12ft side, therefore you would have one 12ft wall, 2 6ft walls and an opening on the other side.
My field shelters for ponies are 12ft by 12ft and there are 3 of them.
Face it with its back to the prevailing wind and make sure it has an overhangs. Also ensure that your horse has enough head room.
RIDE your horse FORWARDS and keep him STRAIGHT
