Adding different types of walls. Some may be full height and others half height walls. Yes we have fences although being able to colour each side differently and a way to add trims on them too. And for more full height walls. Some can include various glass / curtain wall designs (instead of manually adding alot of windows or transparent cube) a plain glass wall can eliminate trying to hide the vertical lines. Although other curtain wall designs would be nice also (instead of placing a lot of windows).
