It is the second tallest building in the city after MahaNakhon, and comprises the Baiyoke Sky Hotel, the tallest hotel in Southeast Asia and the seventh-tallest all-hotel structure in the world.
With the antenna included, the building's height is 328.4 m (1,077 ft), and features a public observatory on the 77th floor, a bar called "Roof Top Bar & Music Lounge" on the 83rd floor, a 360-degree revolving roof deck on the 84th floor and the hotel offers 673 guest rooms.

Construction on the building ended in 1997, with the antenna being added two years later. The Baiyoke Sky Hotel website notes the height without the antenna as 309 m (1,014 ft), but the Council on Tall Buildings and Urban Habitat (CTBUH), Emporis and SkyscraperPage note it as 304 m (997 ft).
Baiyoke 2 was the world's tallest hotel at the time it was completed – but this was never registered in the Guinness Book of World Records. The JW Marriott Marquis Dubai which completed in 2012 is currently the tallest hotel.
