What fence and pavement get me points for sci-fi theme

[ThatACfan]

The title says it all. I want the full gold exterior but I need to max out points so I can unlock it so im doing the sci-fi theme and need to know what fence and mailbox to use.

A concrete fence, grey-brick fence, a rope fence, a shanty fence, and barbed wire fence.
Blue, cyan, green, metal, or stainless mailbox as well.
The pavement doesn't really matter.
