I am so glad more people feel this way, even though there are only four of you 😃. i sent an email to EA, asked if this was something they would consider introducing. I dont think i will bother playing much longer if they are not even thinking about it. I godt this rather arrogant and i guess automatic answer:
"Hey Mayor, thanks for contacting us!
As long as your citizens are happy, they will want to upgrade until the building is so wonderful it can't be improved upon! At the moment there are 6 levels of upgrade available for your residential buildings, skyscrapers are the limit.
So why might you see bigger, better or different buildings in other areas or cities? It depends on the Land Value - how wealthy that area was *when* the building was upgraded. In the residential building menu, tap the blue column icon - you'll see Land Values displayed in blue, which indicate how desirable an area is. The more desirable the area, the more luxurious the residences will become. Tap the yellow hard hat to check to see the Wealth Forecast screen - this will tell you how an upgrade will affect a building's looks. But remember, it's still possible to see an older, less luxurious skyscraper in that dark blue area. It just means that it was upgraded a while ago, when the Land Value of that area was lower.
Make sure to add as many specializations as you can. The more specializations that overlap = the darker the blue areas = the more desirable the area will be to your citizens!
If you'd like to ensure all residential buildings are as luxurious as possible, make sure the areas have high Land Values before you upgrade. If you have an older building that you think is letting the tone of the city down, you can move it further out and start building a new residential zone in its place. If you want to really be extreme, you can demolish it and start again! But be aware, either of those options may result in a drop in your population levels, either by losing those citizens altogether, or losing the population boost you had from nearby services. The life of a Mayor can be tricky sometimes!
The aim of the game is to build your population - if a building is upgradeable and its residents are happy you'll see a hard hat over it to remind you it can be improved upon! There is no way to turn off these notifications."
And so on, feel free to contact us again they said, so I did. saying I just I wanted to know if they would consider making it an option to say "no, i dont want to upgrade this building now, I want it to stay the way it is". A simple yes or no to that question.
I dont think they will answer me again i am afraid
