There must be strict planning controls over new buildings in the rural area north of Coustellet. The new houses are built of the same limestone and in the same style as the established farm houses. In the hameau of Fontcaudette some of the seventeenth century old houses are so clustered that one roofline is merged with another, the terracotta tiles flowing over the entirety.
Further down the road are some new houses which sit up bright and crisp in fresh white limestone. You can see the limestone exposed in road cuttings through the Luberon to Lourmarin and you can see its natural tendency to split into building stones.
