Thai Obayashi Corporation is developing the O-MESH Ratchadamri project, an 8-billion-baht mixed-use development, which is scheduled to open in 2029.
Situated on a roughly 6-rai site at the entrance to Soi Mahatlek Luang 3 on Ratchadamri Road, the project has a gross floor area of more than 117,000 square metres and 36 storeys, or about 177 metres.
The development is to comprise a grade A office building, a 203-room hotel managed by Seibu Prince Hotels Worldwide, and retail space, together with parking for about 900 vehicles.
The development is expected to open in December 2029.
The Ratchadamri project is the first in Thailand to employ left-right-vertical technology, an innovation designed to improve construction efficiency, ensure quality and schedule control, and reduce labour requirements, on-site activities and environmental impacts on neighbouring communities.
The development builds on the longstanding business relationship between Thai Obayashi and Saha Pathana Inter-Holding Plc, a member of Saha Group, adding a real estate joint venture for the hotel component.
The collaboration brings together Saha Group’s expertise in business and project development and Thai Obayashi’s strengths in construction, technology, design and project management.
By jointly developing the project from business development through construction technology, the two organisations are expanding their relationship from business partners to strategic partners and creating long-term value for both the project and the Ratchadamri area.
Pornchai Sitthiyakorn, president of Thai Obayashi, said the site is home to the company’s office and O-MESH is expected to serve as both a technology and knowledge showcase, facilitating the transfer of design and construction expertise to educational institutions and real estate developers.
Functionally, the project is designed to support both work and leisure under the concept “Hotel Supports Office/Office Supports Hotel”.
The development is utilising a smart building system, a destination-control system, indoor air quality management, PM2.5 control, and fresh air supply to create an environment conducive to both productivity and occupants’ quality of life.
Sustainability and environmental, social and governance considerations are also central to the project, with LEED and WELL concepts and criteria incorporated as guiding principles.
The architecture and landscape design are expected to preserve the district’s verdant identity, while adding new value in harmony with the urban context, said Mr Pornchai.
