This marvelous eco-friendly hotel in the desert is an uncommon project of Parisian designer Matali Crasset. Located at the edge of the Sahara desert in Tunisia and overlooking a palm tree oasis, this retreat for relaxation and rejuvenation was designed with ecological conscience and oriental philosophy. The concepts of air -- in the elevated houses -- and dune – in the rooms located by the sand -- are omni-present.Especially intriguing is the presence of Moorish-inspired elements, from the massive yet sinuous wall of the main facade to the small and symbolic perforations in the earth and sand-colored walls, to the blue tiles of the steam rooms.
