In Bhutan you can see the process at work. On the valley edges farmers are building or extending substantial houses while monasteries and temples are being built on outcrops. All the buildings have stone or compacted mud walls and thick timbers, and are elaborately decorated. Even the new airport would be a place of visual pilgrimage in most countries. Everyone feels a compulsion to build a house in his or her lifetime.
Building is a part of the life of the community.
Building is not a commercial activity. In villages the community joins in. Trees are selected by a forester, in exchange for planting two to replace each one taken. They are adzed into shape and slid down the hill. Walls are of mud tamped into shutters by teams of singing women.
