Architecture And Construction

Wandeegroup Asia Co Ltd is an esteemed architecture and construction company based in Pattaya, operating since 2004 under the name Wandeegroup (Thailand) Co. Ltd. Under the visionary leadership of founder and CEO, Mario Kleff, the company has established a strong footprint in the industry.


  • Comprehensive architectural solutions including concept, pre-design, schematic design, design development, planning, and permitting
  • Scale model, production, 3D/CGI and animation
  • Construction management, supervision, and construction services for buildings up to 12 floors or 10,000 sqm

In recent years, we've been proud to design remarkable projects such as the Wong Amat Tower and The Touch®, resorts, hotels, eight-story apartment blocks, department stores, and luxury villas.

Mario Kleff has designed over 150 buildings worldwide, including in Thailand, the USA, Dubai, Laos, and South Africa. However, it's notable that while these international projects progressed to the design phase, construction did not commence. A notable example is the redesign of the Thakhek Dream World City development in Laos, originally conceived by Somjith Aliyaphaphonein of Akane Development Lao SEZ Co Ltd in 2015, Mario Kleff and Dr. Songkiat Matuyapont to redesign the project in 2018.

Despite these setbacks, Mario's commitment to innovative and minimalist architectural design remains unwavering. Kleff's Bauhaus design South Beach Boutique Chic was unveiled on 17 May 2012 and recognized as the Best Boutique Condo Development on the Eastern Seaboard at the 2012 Thailand Property Awards.

Now a proud citizen of Thailand, his creations within the country encompass a vast range of structures that serve as a testament to his unique vision.

Mario’s avant-garde designs have gained significant recognition, solidifying his reputation as a trendsetter. As a prominent developer from Pattaya put it, A leading development requires a leading designer, and in the peerless CEO Mario Kleff and his Wandeegroup there can be no finer selection, Haim Bar-David.

Since 2009, Wandeegroup has consistently taken the lead in submitting project planning proposals to Pattaya's Construction Department. In recognition of his dedication and expertise in architectural design, Mario Kleff was distinguished in 2010 with a Letter of Recommendation for a PhD by Pichet Uthaiwattananonta, the Head of the Construction Department at Pattaya City-Hall. This accolade underscores our unwavering commitment to architectural excellence.
