A Canvas Cabin is a BIG tent. Even so, you might find yourself needing more room. This is easily done. You can add a six or nine foot extension to your tent, either open at one end--a porch fly--or fully enclosed--an add-a-room. Simple to set up and adds half again as much floor space. Easy on the pocket book too and can be added at any time. A Porch Fly or Add-A-Room is a great place to cook, keep wood dry, take off muddy boots and can also be equipped with a stove jack and sod cloth.
