Can I rotate buildings?
No, it's not possible to rotate buildings.
This has two reasons:
1. We don't want to make it too easy to rearrange the city. The missing option to rotate buildings makes the game more difficult - like a puzzle.
2. The buildings are currently only animated from one angle. To add a rotate function would mean to overhaul all existing buildings and animate them from all kind of angles. We would rather invest this time in cool new features.
If you don't have enough space in your city, you can sell your existing buildings or rearrange the city to use the available area more efficiently.
