Baiyoke Tower II, located on 222 Rajprarop Road in the Ratchathewi district of Bangkok is Thailand's tallest building. It contains the Baiyoke Sky Hotel, the tallest hotel in Southeast Asia, and the fourth-tallest all-hotel structure in the world.
The building is 304 m (997 ft) tall, or 328 m (1,076 ft) tall with the antenna included. It has 85 floors, with 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 itself lists the height without the antenna as 309 m (1,014 ft), but the Council on Tall Buildings and Urban Habitat (CTBUH), Emporis, and SkyscraperPage list it as 304 m (997 ft).
Ocean 1 Tower in Pattaya when completed, expected 2012, will be 367 m tall and so become Thailand's tallest building. It will also be the tallest all residential building in the world.
