What if modern civilization just stopped and suddenly, you had to fend for yourself? Basic Age of Empires logic tells us that wood and stone are what you need to head for straightaway if you want to start building homes.
Here's a brilliant video by Primitive Technology that shows you how to go about it. This is what the video description reads -
I built this hut in the bush using naturally occurring materials and primitive tools. The hut is 2m wide and 2m long, the side walls are 1m high and the ridge line (highest point) is 2m high giving a roof angle of 45 degrees. A bed was built inside and it takes up a little less than half the hut. The tools used were a stone hand axe to chop wood, fire sticks to make fire, a digging stick for digging and clay pots to carry water. The materials used in the hut were wood for the frame, vine and lawyer cane for lashings and mud for daubing. Broad leaves were initially used as thatch which worked well for about four months before starting to rot. The roof was then covered with sheets of paper bark which proved to be a better roofing material. An external fireplace and chimney were also built to reduce smoke inside. The hut is a small yet comfortable shelter and provides room to store tools and materials out of the weather.
