I believe it's the Gothic architecture type that's similar. I mean the roofs should be more vertical. Hard to explain, but they should look more sharp. Firstly, your new farmstead looks great, well done, but I meant a plank shingle roof (like the ones commonly used in the Dark ages). This house is a Gaulish city longhouse. I believe this is a perfect representation of what one of the varying houses (by varying house, I mean how there are different types of house that will randomly be selected when placing a house) in the city stage. In the original post, you will see that all the houses are similar in architecture (some being ''double story'' as in being tall enough for it to possess an attic) but they vary from thatch to wooden shingle. If it were made that those types of houses were used in the city phase and the current ones used in the town phase, that'd be perfect. What I've noticed is I struggle to build a village-like village with the romans due to their massive civic centre and houses, and I struggle to make an urban looking city with the Gauls, simply because every building has a thatch roof. If the the thatch in the city phase were made to look darker (like older thatch) then I imagine it'd look more urban. Edit: The image I posted of Bibracte is a perfect example of what the Gallic city should look like; more longhouses, some houses with shingle roofs etc.
