Inspiration: Materials

I come across this really unique material on Pinterest which I thought  could have been intersting to use on the rooftop due to its sustainability to weather with it being concrete but also being transparent which fits in with the theme of work i would have like to have gone with.

Transparent concrete, by Mexican students Joel Sosa and Sergio Omar Galván, is 30% lighter than normal concrete and lets through 80% of the light.
