Ecohousing example - Parc Eirin development in Cardiff

Saw this on twitter today and had to share. Really useful to see a demonstration project like this come to life and be explained. I do agree with a few of the comments on the youtube video about building in green space and wildlife into the development, something worthwhile considering for those doing something similar.

What do you think - recommend any improvements?

Very heartening to know this kind of work is going on.
