There's also some inversions of ICF where the insulating foam is on the inside and the concrete blocks are layers on the outside. OmniBlock is the manufacturer that I can remember but there may be others. Not sure what the tradeoffs are but I'd assume two big pros are (1) concrete's easier to attach things to and (2) concrete can be directly finished both on the exterior and interior. I'm not sure how people run electrical and other utility through these. And I'd expect that half the inspection / code in the US has no idea how to handle either ICF or related, but I'd love to be wrong.
