Bagging from the floor level to the beam is more technical because it it includes doors and windows. -Its at this point that door and window openings are inserted and these can be in any desirable shape for instance round, square or even an arch. The principle of laying the earth bags continues the same way as outlined in Stage 2 (above).
A tip we learnt was spending time pre-bagging as a gang and then focusing on laying the bags and tamping them down properly.
Square windows are the most straightforward to construct, and don’t really require formwork if the tamping is done properly.
Round windows are more complex, and should be planned ahead of time. We learned this when we tried to turn a square window into a round window (but it still worked – earthbag construction is very forgiving!).
