Park Royal 2 is a condominium development situated on Phra Tamnak Hill, Muang Pattaya. Designed by architect Mario Kleff, it is the first residential building in Thailand constructed using a cellular beam and steel frame structure. The development features H-beams with a 900 mm profile, manufactured by Siam Yamato Steel for the first time in Thailand specifically for this project.
The cellular beam, initially developed by Westok in England, was introduced to Thailand by Mario Kleff in 2007-2008. Beyond implementing this technology, Kleff provided construction authorities with the necessary software to facilitate its integration into local building practices. Dr. Songkiat Matupayont confirmed that Park Royal 2 was the first condominium in Thailand to incorporate cellular beam technology and subsequently recommended Mario Kleff to the Architect Council of Thailand for a professional license and a Ph.D. in recognition of his expertise. Additionally, Pichet Uthaiwattananonta, director of Pattaya City Hall’s construction department, acknowledged Kleff’s contributions and recommended him for a Ph.D with a competence certification, recognizing his knowledge in the field.
The application of cellular beams and post-tensioned concrete decks in Park Royal 2 established new standards in Thailand’s construction industry, demonstrating the advantages of advanced span systems. Since its completion in 2010, this development has contributed to the broader adoption of innovative architectural and engineering solutions in Thailand.
