Back to School
Put down your drill – not quite there yet! Here comes the fun bit.. no really!! So if I mention Pi and Pythagorus’ theory you know where I am at then you can ‘pass go and collect £200′ otherwise hang on in there..
Pi – 3.14 A magic number really, the greeks really were fantastic at their maths.. It relates to the relative distance of the circumference of a circle to its diameter.. That is to say a Circle is 3.14 times larger than its diameter (whole distance across the circle). You can also work out area of a circle as well which is great but read up on it further here : http://en.wikipedia.org/wiki/Pi
Pythagorus Theory – This is the crux of what you need
But again need to understand this and where there is already a (better) resource I will point you in the right direction!

I think this is very important to understand, it gives you flexibility and the knowledge to make your yurt your own..
There are plans out there that you can use, or I could give you one myself but this isn’t the best way to go.. or at least if you do go that way I think you should understand the why’s of everything – if only so you can appreciate the beauty of its brilliance!
Get a template by all means but what if you want to adapt the design to let more light in? – A bigger crown / roof ring. What if you are 6′+ and sick of knocking you head on doors? – A larger door.. etc
It is worth noting that the yurt structure is flexible by its very nature, it is not precision engineering, there is a tolerance of error to work in. I say this not so you have an excuse in case you get something wrong and just move on, everything should be right. But remember the yurt is an ancient structure that, like then, is still used today throughout the Asia steppe. It is being erected daily as the nomadic tribes of the area call it home. Whilst the ground may be visually quite flat, it is also the earth and so isn’t! Anyway the yurt takes this in its stride and through the flexibility inherent in the structure it work perfectly.
TO BUILD A 16′ YURT WITH 6′ HIGH DOOR AND 10′ IN HEIGHT
The elements you need to sort out and decide upon before starting:
The Khana / Wall
The diameter of the yurt dictates the circumferance of the yurt.. So if you want a 16′ yurt then it will be (16*3.14=) 50.24′ (this also includes the door)
Now decide upon the spacing of the knots – this is part needs to relate to the strength of the timber.. If it is weak timber the spacing needs to be alot less, maybe 6″ and if strong then 12″ or even 18″ can be used.. For example a 1″ hazel / willow rod can be used at 12″ spacing.. the spacing can be any distance (e.g 9″, or 10″, or 10.5″!) and you will see why in a minute..
Once you have decided on the wall you want - height and length this will dictate the length of each individual piece of the khana. We want a 6′ door and as we are going for a traditional design with bent roof poles this will add 1′ onto the wall height before the roof slant begins, the walls only need to be 5′ high.
Using pythagorus’ theory : to get 5′ high with a right angled triangle the hypotenuse needs to be…. (sqrt(5*5 + 5*5))
…7′.07 or lets call is 7′ which equals 84″
I have just tried to continue describe the intricacies of the further calculations but to be fair it is too complicated without diagrams which I haven’t created yet.. there are calculators out there which I advise you use..
..or Email me at info@wildinstyle.co.uk and I will provide you with further info..
The Uni / Roof poles
The number is indicated by the calculations above as the number of X’s at the top of each wall tip will have a roof pole.. these will then travel up to the crown
The Tono / Crown
This is created to whatever size you prefer.. I like the bigger the better, the reasons for this are that I enjoy the light that streams in through the roof and by having a larger roof ring it requires shorter poles and to a certain extent less weight. Traditionally which is the style I will be using the holes in the roof ring are burnt out using hot metal straight from the forge.
The Door
The frame is the important thing here with regards the structure.. The door just fills the hole, it isn’t needed although I wouldn’t have a yurt up for any length of time without some kind of door on if it has a canvas on – think sail and wind! But the door can be made of canvas or wood, styles and wood types all vary according to taste, weight and ability
The canvas
This requires you to have space, strength (as that quantity of material is heavy) and an industrial sewing machine
The Floor
Not a requirement as it can sit on the floor but something to think about as you don’t want the yurt sat on wet ground or in mud..
