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).
MahaNakhon by Pace Development currently under construction will be 314 m (1,030 ft) tall measured as height without antenna, replacing Baiyoke II as Thailand's tallest building when completed in 2015. The planned Ocean 1 Tower in Pattaya, currently on hold, will be 367 m (1,204 ft) and so become Thailand's tallest building. It will also be the tallest all-residential building in the world.
