The graphs demonstrate the difference in a manufacturing area called Norbiton between the present and its planned evolution in the future.
Overall, what can be witnessed is that factories around the district will all be replaced with housing, and due to that, more facilities will be added.
To begin with, a bridge will be built to connect the center of the sector with the area across the river. Therefore, the horizontal factory will be removed and rebuilt vertically next to the center as a house. Moreover, it can be noticed that there will be a variety in accommodation sizes; for example, the two houses on either side of the playground are almost half the size of the one across it.
To add on, different amenities will be constructed all around the area: a school, a playground, shops, and a medical center to turn the industrial area into a living one.
