I know the frustration about fitting buildings to irregular shapes. But it looks like a good job so far.

Shessar, I think the number of stairs you show is correct. However, the flow confuses me. I have indicated what my concerns are in red. The arrows would seem to be the way people would ascend the stairs - first, I think the wall of the second part of the staircase is in the wrong position and should be where the red line is (or both); and perhaps there should be a secondary landing between the two parts of the stairs - only spiral stairs have no landing as they ascend if the direction is changed.

Something like this? (Symbol from Dundjinni Archive - Structures>Stairs)

The ceiling height can be either determined first, eg 8-9'; and the number of stairs required worked out eg, each step 6", then 9' ceiling requires 18 steps to reach upper floor, ie 9 steps for each of the two sides of the staircase. Medieval inns would be likely to have ceilings no bigger than 9', and stairs were fairly steep, so 6" is about right, I think. You have 6-7 steps per side, so that would possibly do for a 8' ceiling or steps taller than 6", say 7.5" to give ~ 9' ceiling.

But all this is being very pedantic, I know.

The symbol shown has 12 steps each side, so if the steps were only 5" tall, the ceiling could be a majestic 10'!!! This therefore gives plenty of leeway in the actual height of the ceiling - just increase or reduce the depth of each stair to get the desired ceiling height for the number of steps shown in the symbol. But I would definitely add the intermediate landing.

Here is the finished city - just got to do something with the marshes and sea to break up the repeating pattern.

Thanks, @Don Anderson Jr. for that tip. Thanks for the compliment.

Can I have that carpet for my home - tres magnifique
