Do I qualify as a sustainable self-build?

Answer: 

Admittedly, this can sometimes be seen as a grey area! Although thePOOSH.org does not lay down any 'hard rules,' we do suggest you always search for environmentally-friendly alternatives to conventional building. It is encouraged that there's an open dialogue between POOSHers and build project hosts about what is considered sustainable. If a POOSHer suggests a more sustainable way of carrying out a task, take this into consideration and talk about it!
