Does it matter where I place my embassies and customs houses?
Some buildings, including embassies and customs houses, do not need any workers and do not have any obvious effects on their surroundings. Does it matter at all where I place them?
Solution 1:
Embassies can be placed anywhere, supposing they are initially close enough to a road/construction office to be built in the first place. I place them in areas that are not very desirable so I'm not wasting prime real estate.
Custom houses do take 4 illiterate people to run them, so they matter only as much as it matters that you have housing nearby for the employees to live in.
