Hi Michael, The longest Fully Assembled building that we can ship is 40', but we have lots of different kits. While we do not have the instructions on joining multiple buildings, we have had quite a few successful clients. Here is a link to our catalog. It has all of our designs, sizes, and current prices. https://s3.amazonaws.com/jamaicacottageshop.com/uploads/JCSsale.pdf Feel free to message us again or call M-F 9-5 or Sa/Su 9-4 EST 866-297-3760
You wouldn't be able to transport a 70' unit but I'm sure they could adapt one of their plans and put a kit together, they were great when I called
