Design and location
The tower is the shape of a square prism with the appearance of a rough spiral with cuboidal surfaces cut into the side of the building. The building features a pixelated ribbon that swirls around the exterior, peeling back its surface layer to expose an inner layer, creating balconies with views of the city. The glass walls are divided horizontally and vertically, adding to the building's "pixelated" appearance. Its height surpassed that of the Baiyoke Tower II's record of at the time of completion in 2016, making it the 88th tallest building in the world. Among the features of the building are: of retail space ; 209 residences serviced by Ritz-Carlton, which, with prices ranging from approximately 42 – 500 million baht, are among the highest prices asked for Thai luxury real estate, freehold or leasehold in Bangkok; the Orient Express Bangkok hotel, with 154 rooms including 9 suite and 2 penthouses, to be operated by AccorHotels; as well as a rooftop observation deck. MahaNakhon at one point featured Thailand's first L'Atelier de Joël Robuchon, Thailand's first restaurant by Iron Chef Masaharu Morimoto, Thailand's first Vogue Lounge, and the largest Dean & DeLuca in Thailand, however all retail outlets have been closed in 2019 pending redevelopment by the new owners.
