On an island off the coast of Aceh on the far north-west tip of Sumatra, Indonesia, Neal Cross is sitting in a tree house. It’s not just any tree house: it’s a work of some skill, high in the boughs, linking directly to the upper floor of a house he has built here next to his boutique hotel.
It has been constructed without a single nail being driven into the tree nor any permanent connection to the tree itself. It drifts back and forward in the wind while he looks out over the Andaman Sea, writing presentations on his laptop.
