The cob universal compost toilet for the education centre. It’s taken 4 strong, young, enthusiastic post grads four weeks to get this far , working 5 days a week . I can’t help but think that the amount of time and energy to hand build using Cob ( mud and straw trodden into a mixture ) doesn’t quite add up - of course it is the ultimate eco building technique . But you’d have be happy in mud to undertake it . Really hope that there’s a plan to get it finished ....
