Hi Hime,
I live in Naivasha and we have been doing cob buildings for about 10 years. You are welcome to come and see what we are doing and I also have a trained team that may be able to help you get started. Lately we have been using eucalyptus poles with chicken wire on either wide of pole which we fill with trash and then cover with cob. We have made quite a few buildings and 2 bedroom cottage using this technique. Let us know if you would like more info and I can send you my email.
