A new Foster + Partners-designed Four Seasons Casablanca is set to open in Q4 2015, including a 700sq m (7,535 sq ft) Le Spa with 10 treatment rooms.

The spa will feature cedar and local stone textures, with argan oil-inspired gold accents glowing beneath perforated Moroccan lanterns.

It will include sensory showers, ice fountains, a balneo hydrotherapy pool, steam rooms, saunas, and men’s and women’s relaxation lounges and change rooms. Spa director Gaelle Peiffer has also designed special spa experiences for children and teens.

Treatment highlights will include the Skin Instant Lab by Biologique Recherche and a new concept in partnership with supplier ila that will reflect "the alchemy of the ancient Moors of North Africa." Some treatments will use emerald, etan and gold.

The spa also features dedicated treatments for kids and teens, including a Fruity Scrub, massage discovery for kids and back and facial treatments for teens.

"I would like to create an exemplary spa experience, where guests can try one of our innovative and therapeutic treatments, relax in our whirlpool or enjoy a traditional Moroccan hammam with the highest quality sourced products," said Peiffer.

The spa area includes a 172sq m (1,850sq ft) fitness centre for solo workouts or private classes and a 149sq m (1,604sq ft) pool with private cabanas. Spa equipment will be supplied by Gharieni.

The hotel features interior design from GA Design and design for its three restaurants from EDG.

"Modern Moroccan elegance characterises the design, textures and colour palette” of the 157 bedrooms and 29 suites, the company said. A highlight is a 329sq m (4,220 sq ft), three-bedroom Royal Suite with 180-degree floor-to-ceiling ocean views, private terrace and indoor-outdoor fireplace.
