But the wattle and daub,
I’ve spent some time at Plimoth Plantation – ( plimoth.org ) a living history re-enactment of IIRC the third year of the Pilgrims original colony at Plymouth, Ma.
I was there several weekends over about 3 months and was allowed by the re-enactors to help a bit. One of the things I got to help with was a timber framed wattle and daub home they were building. Make no mistake about it, from squaring the timbers to “wattling” and “daubing”, it’s work.
Having lived in 8 man tents before (once upon a time; many, many years ago in a land far, far away, I can understand the size/space issues. If you did a loft, your sleeping area would be separate from your living/cooking area. Would it get close after a while? probably but it would be dry and hopefully warm in the winter.
