This is the sketchydoodle of the communal bosaleph house.
the idea is that it sits in the middle of their farmland. it takes up little space and therefore leaves more space available for farming.
the lower area is the communal area and the upper area is segmented into rooms that they sleep in. The entire structure is made of wood with large open windows that will most likely not have glass. they will have curtains, however. The roof is wood (most likely) and is designed with a slight curve so water doesn't collapse it, and in hte case it snows (as long as it doesn't snow too much) it can hold the weight.
