Mecca proposes to build hotel by 2017. The 10,000-room Abraj Kudai hotel will be built in the Manafia district, just south of the Grand Mosque. With twelve 44-story towers containing 10,000 rooms, the hotel, which is being created by multi-national design group Dar Al Handasah will have a total area of 4.6 million sq ft. Each tower will hold approximately 1,200 luxury rooms measuring roughly 45 square meters. Work has already begun on the $3.5 billion project, which will feature 70 restaurants, multiple helipads, whole floors devoted to royalty and one of the largest domes in the world. London-based design firm Areen Hospitality is in charge of decking out the interior spaces of the hotel.
