The word henge refers to a particular type of earthwork of the Neolithic period, typically consisting of a roughly circular or oval-shaped bank with an internal ditch surrounding a central flat area of more than 20 m (66 ft) in diameter?
You list some materials, how do you propose to use them?
If the area is very damp for some of the year, what are your plans to ensure it does not ingress the structure?
If you have very thick walls, 600mm to 800mm replicating what the Northern Europeans built
their experience will help you. What floor material do you propose to implement?

Especially since you have the materials at hand to build. Of course a bale structure on a rubble trench with maximum insulated roof and a mass stove is best, but this structure is not intended, I believe, for year round living.
If the stove isn't being fired regularly, every day at least, during the cool months, it probably won't work well in the winter. I lived for three years in a 300 square foot cob house in Western Montana, and it worked well for staying warm year round with no insulation in the floor and a living roof with next to no insulation underneath. Of course, your structure is 1/3 that size, and a rocket stove with a big exposed barrel would kick radiant heat off fast for immediate needs and would probably work really well.
Again, for the purpose you proposed above, I think it would be exactly what you want. Love to see pictures when you start, keep us up to date.

Took a solid year to build, but I was working full time on the house digging the foundation by hand and mixing cob by foot. A loft is a good idea for a bed, maybe a crawl in that is just a bed so you don't need to build as high.
I love the balecob house, it is best of both worlds. Insulation with maximum amount of thermal mass. This February, my wife and I walked away from the house for 9 days and the temperature dropped from 20C to 14C. The average temperature during that time was about 0C.

Is that possible with a frost line deep in the ground?

Thus maintaining the interior dimensions required?
