The first:
The Hall
The Hall would be a building similar to our current timber house. It would look the same, and it would be the same, but, it would be twice(?) as long, and twice as many materials.
The main reason I like this idea is it could be used as a meeting room for a village. It could also be used as a dining hall for your big village.
I'm not sure about the twice as long, I just want something for a larger timber house that could have more uses than the timber house.
The sprite? Pretty much just a stretched out timber house.
It would also be nice to have a cellar. Any size would do.
Great Hall
The Great Hall would be similar to the hall, but it would be the Stone Mansion equivalent. Same size as hall, just two floors.
Similar sprite to the stone mansion, just stretched again.
Cellar, too.

City Counsel
It would pretty much be the the Hirdsman, but for Lawspeaker.
This would useful for secondary Lawspeakers if he goes inactive. They, also, could be summoned.
They could use a different name, possibly.
If you have a better idea on how to use this, do tell.
