Amanda and I have built a mudbrick house at Panton Hill, Victoria, Australia. It is an octagon two story house with half of downstairs under ground. Upstairs is one large room where we have our Kitchen, Living Room and Office.
Our house has Solar Hot Water, Solar Power (which make up for about 2/3 of our power consumption or more over a year), internet connection, phone system and a varying amount of automation (I am always changing things). You can see more about my house in Quests.
