Too low for both. It was built when ADAS funded it and came up with idea of low roof thinking it was better for sheep! As it is now it’s pretty useless. Be a shame to pull it down and leave perfectly good steel, if not better than what you get these days to pile up and be forgotten about!Is it too low for the machinery used for the job or too low regarding ventilation? By the time you strip and remove roof and extend stanchions you will be nearly at buying a new kit form type if price to stick somewhere else!!!
