Castos Construction Sets

Castos was an unusual construction system for making buildings and bridges out of concrete. It was made in England by Architoys from 1947. It was not a great success and only lasted a few years.

A paper presented by Brenda Vale and Robert Vale of the Victoria University of Wellington to the 2017 Conference of the New Zealand Concrete Industry gives a lot of information about Castos here.
