Cube houses were radical back in the day and they are still there in Rotterdam more than 50 years later. A more recent experiment in Amsterdam is also worth mentioning: http://www.tempohousing.com/projects/keetwonen/ http://www.tempohousing.com/projects/keetwonen/ This is basically a project where they built cheap student housing using pre-fabricated container sized units for a 1000+ students. Apparently, the company behind this, Tempohousing, has been running projects around the world building temporary housing using shipping containers for refugees, homeless people, and other use cases, etc. There are a few more companies doing similar things at this point.
