German Boy Scouts usually use the cotton tent TORTUGA KOHTE.
It exists in two sizes, 4 to 6 and 4 to 8 persons.
You can ignite a well sized camp fire in it.
The stuff isn't idiot proof but in my opinion the best group tent construction that exists.
I highly recommend to choose the most usual version S20 with 4 equal tent sheets for 4 persons or 2 adults and 4 children.

With 6 of such tent sheets and 12 square tent sheets you can construct a yurt. In it can sit up to 30 persons. Here you can also ignite an even larger fire inside of course.
This video shows another one but it gives you an impression what you get with 6 + 12 classical sheets.

The in my opinion by far the best option is the larger Tortuga Wanderkohte because here fit up to 8 adults in, but it can be carried well together with the usual other luggage by 4 persons.

One can construct out of each single tent sheet a 2 person tent with open entrance.
Out of this material you can NOT construct a yurt.
