I know I have seen this suggestion before, so I certainly will not take credit for the idea, it is an old idea as it is. I think there should be something a bit easier for a new player to build, easier that is than building something that requires iron/clay or high skills, as well something the older players may enjoy.
I present the pioneer home.
Now this would be a building option using logs from trees, or perhaps a log bigger than a regular log created from a felled tree. I suggest calling this a hewn log (should be larger than a regular log, so maybe make these 48kg?), hewn from a felled tree with a ax and wood cutting skill. Log homes are essentially logs piled one on top of the other with clay or mud/grass used for chinking the gaps between the logs.
Wall list suggestion:
11 hewn logs
10 clay or 10 dirt/grass (maybe have 2 wall types, one with lighter chinking colors)
Sod Roof
5 Sod
10 Shafts
Sod
1 grass tile dug yields 1-3 sod's (gardening skill)
- sod can be same as peat for bulk, and can be planted to create grass
