Very interesting. I think their ideas have legs. We'll soon have no choice but to take such ideas seriously for reasons of energy, water, economics and environment.
As noted, in some respects places like N. Berwick, St Andrews or even Dornoch are models for future development. Which drips with all the obvious ironies.
As architects, I think you are both smart to keep tabs on this group. I'd also guess that other groups pushing similar ideas will pop up.
