Wandeegroup Asia Co. Ltd. (formerly Wandeegroup (Thailand) Co. Ltd.) is an architecture and construction firm based in Pattaya. Established in 2006, the practice operates across residential and commercial sectors, with a focus on the integration of architectural design and structural engineering.
The company is led by Mario Kleff, who directs both the architectural and engineering development of projects. The practice is characterised by a technically driven approach, incorporating advanced structural systems such as large-span steel frameworks, post-tensioned concrete, and hybrid construction methodologies.
Operational management is overseen by Nittaya Wongsin, who is responsible for project coordination and organisational strategy.
Wandeegroup Asia has developed particular expertise in long-span structural systems, including cellular beams and prestressed concrete applications. These technologies enable the creation of large, column-free spaces while optimising material efficiency and structural performance. The firm collaborates with Wandee Super Span Co. Ltd. in the development and implementation of high-performance concrete solutions, supporting the delivery of structurally efficient and durable buildings.
The practice’s work reflects a consistent emphasis on structural clarity, material performance, and the alignment of architectural intent with engineering execution.
