If you search around you'll find open days where you can go through all these sorts of houses and get some great ideas and meet some really nice people who are only too keen to give helpful advice .......we also used to get the owner builders magazine for years which had some good stuff in it , a lot of the people building with straw bales tend to do post and beam contruction as it keeps the weather off as well as adding support for roofs , windows and doors............a few even just bought custom kit sheds and omitted the wall iron cladding and used straw/mudbrick etc to do the walling, you just have to make the required footings to suit.....very easy and quick solution hey
Good luck with which ever way it happens for you !
