Anything by Nihei Tsutomu. He used to be an architect, then started le making epic sci-fi mangas.
^this. I've read Blame! and loved it to bits. It's basically 95% wide-ranging shots of architecture, and the protagonist has a little handgun which carves fifty-kilometer shafts in solid metal
at its lowest setting and yet it all works because the whole thing just oozes atmosphere. It put me very much in mind of
The Last of All Suns.
