I have no experience with this maker, but have lived in a 20' diameter Tipi for awhile. First, with proper setup, the bottom will not have such a gap as shown in their illustrations. They are warm, even in very cold weather, because of the ability to have a fire in the center of the lodge. They are more work than most other modern tents to set up properly, but with practice, one person can do it with relative ease.
Before I bid, I would ask if the waterproofing agent and mildew retardent are flammable and toxic to breath. Different countries have different regulations for such things. Also, I would opt for the lining, which should be fire resistent. It also helps with the channeling of air inside of the lodge.
The lodge is designed to resist high winds, so the length and diameter of the poles is very important. For a length, some say the longer the better, but actually the ideal length is from 1.2 to 1.4 times the diameter of the lodge. So, from 12-14' for a 10' lodge. Diameter for the poles on that size lodge should be from 2-2 1/2" where they cross. I have seen poles that were sectioned and fastened together with fittings to shorten the poles for ease of transport. They can be purchased like this here in the states, so you may want to ask if they offer that as an option.
), but judging from the heat that was in there with a small fire you'd be good to some low temp's. i also dont think you'd be able to carry it. in a car/horse back/dog sled or sommit you'd be good.
