David Freeman on Round Houses 

In usa? How? Which state?

Well, I ended up so far building a wattle and daub house for my family with a modern roof. We are living in the house in New Mexico, USA for the past 4 years. I still hope to build one with the conical thatched roof here at some point! @@user-ei2nr1qg5g

Yeah Celts, same people.

My later experiments pushed wall hieghts up to 2m

Maybe it's your job to rebuild it.

@@user-ei2nr1qg5g maybe you’re correct.

Suprisingly, the neolithic farmers built long houses, but as the pressure on the land increased, materials got smalerl, and at the end of the period they went over to round houses because they were stronger than a wobbly longhouse!

@@gdfreeman1950 Oh I see. But in the stone age they had round tents wight?

Right

@@jakobpetrov1750 early stone age folks were more mobile, and evidence suggests shelters and tents. Don't forget the climate was much warmer after the ice age, and did not drop to present levels until late iron age.

@@gdfreeman1950 Thanks for the answers. I have one more question. I am interested if there is a possibility of getting to this Butser Farm with Erasmus as a student to have practical lessons there do you have this possibility ?
