Mud Bricks are Fantastic way to build.... I have played around with some helping a mate build his hone... 3br 2 story Muddie for around $35k... Very Cheap.. Easy to lay, or get a brickie in for a few days to show you the way... You can make your own bricks and there is heaps of info on the net about them... You need to get your mixture just right tho and you can, With the help of a Bobcat/Backhoe knock out 100 + bricks a day. Drying time will depend on Mixture, Temperature and Humidity... What type of Soil/clay do you have on your Block? This is very important..... and im sure, as they are very Popular down south, plenty of people to help you out.. I have about 150 issues of 'Owner Builder' Magazine and they focus on Rammed Earth, Mudbricks, Cob Method (Very easy)... This is how I am going to build one day.. If you are not keen to make them, you can buy them but they are not a cheap thing unless you get Seconds... There is a group of People, I think they call themselves WWOOF... And they can help with Labour, Advise ect.... I can have a look through some mags and find some Web-sites for you, but Googling would likely be Quicker....
