To have the best (most luxurious) skyscrapers you have to have all services and 2 or 3 specialization buildings. Lets say I have no specialization buildings at all. What will happen:
1) I will upgrade my homes to the maximum, so placing later specialization buildings will not help me and I will have to demolish all upgraded homes and start all over again to have the best (nicest, most luxurious) of them.
2) after placing specialization buildings they will change by theme self to new graphic
3) I will be able to upgrade them once more and during this upgrade they will become more luxurious.

I have found out that once you upgrade the home for max pop that building is locked at it's wealth level. Is there any way to downgrade building one level?
