Basing off my previous question, in what way should the architecture be like in order to accommodate the many sizes of people and animal-people, assuming that the smallest could be as small as a few inches tall to over 18 feet tall?
I would imagine that for starters, doors and hallways would simply be big enough to accommodate 18-foot-tall giants, which would be ergonomic for the many different peoples who will be walking through, but would that be practical to over-engineer everything in such a way. However, this would be the capital, so I imagine that would be little to no expenses spared.
On the other hand, how should other common things be sized or designed? Things such as chairs, table, cutlery, plates, park benches. If they were all simply sized to fit the biggest people, then the smaller people would find it difficult to impossible to use. What sort of design paradigm would allow for universally ergonomic tools and furniture.
PS: Only public things need to be designed this way, personal things such as beds, drawers or work stations can be roughly tailor fitted for the person using it
EDIT 1: Within the capital, the ruling class are generally humans, but there are people with high amounts of political power of many sizes, so it would be preferable if it would accommodate them as well
