Upgrades (Buildings not improvable)
In a Paris set up for educational purposes, I am trying to upgrade some buildings using the action (Flat roofs -> Green roofs) but even if I own or buy the building, it indicates that the building is not improvable. I remember in one of the discussion, it was said that we cannot improve new buildings but this is not the case here. Do you think it may be related to the simulation of the buildings, which are from the start considered as modern or new and therefore not improvable?
Thank you in advance for your help!
