After the experience of the HI hotel in Nice, now Dar HI in Nefta is the fruit of the collaboration between Matali Crasset, Patrick Elouarghi and Philippe Chapelet with a new concept of eco-retreat. Matali literally rose a citadel, from the sand, dedicated to well being. Protected by surrounding walls, you find a composition of elevated houses that constitute the Dar HI as a small village. The overall architectural goal was to give a strong proposition while in harmony with the natural site and the local life.
