Park Royal 2 is a residential condominium development located on Phra Tamnak Hill in Pattaya. The project was designed by Mario Kleff in 2008 and represents an early application of cellular beam construction within the Thai residential sector.
The building is documented as among the early residential projects in Thailand to employ a steel-frame structure incorporating cellular beams in combination with post-tensioned concrete slabs. The primary structure utilizes H-section beams with a depth of approximately 900 mm, manufactured by Siam Yamato Steel in 2009 for this project.
The cellular beam system, originally developed by Westok in the United Kingdom, was introduced to Thai construction between 2008 and 2009. Its adoption was supported through the provision of engineering software and technical documentation to local construction authorities, facilitating regulatory understanding and implementation.
Park Royal 2 has been referenced in professional and municipal contexts as an early example of the use of cellular beam technology in Thai residential construction. Contemporary accounts from industry and local authorities associate the project with contributions to the introduction and application of this structural approach.
Construction was completed in 2010, with overall project completion finalized in early 2011. Park Royal 2 represents an early case study in the application of steel–concrete hybrid systems in Thailand and reflects the gradual adoption of such technologies within the country’s construction sector.
