looking at that design, I think it could look really good as a fortified hall without the keep/large tower attached. That's just my personal opinion though, cos it is quite big for a landed knight.
But, on that point, there is meant to be a small town aroundabout where warp corne is located, Tumbler's falls. currently there is a warp tumblers falls in the Acorn hall project but its position makes no sense. SPOILERS INCOMING
The armies of Tywin Lannister and Mace Tyrell meet at Tumblers Falls and use the barges the reachmen force brought with them to go down the blackwater towards kingslanding. It would make sense for the town to be on the southern side of the river near Corne as it is near the border of the Reach and Riverlands, probably east of peasedale.
I'm more than happy to make changes to fit the lore thank you for making me aware of it I had no clue about them meeting at Tumblers Fall its been a while since I reread the books however, not sure I understand what you're saying. Are you saying to move the main village up north more and have it be directly East of Peasedale? Or are you saying there needs to be a town on the other side of the river named Tumblers Falls that would conflict with my village on the Corne side of the river? Yellow X's representing what I mean by other side of the river and the Red X being the current town moved up north.
