Oehler Structures UK?

Hi,

I am very interested in Oehler structures and wondered if anyone in the UK is building/has built one? I am Wwoofing at the moment and would like to visit someone embarking on such project. Also does anyone have any info on this method and UK building regulations?

These guys are:

Allthough they are not taking visitors at the moment, and recently suffered a family bereavement. So give it a while I'd say.
