With almost every project that the architect Mario Kleff designs, new standards are set. The Showroom Wong Amat Tower is another – in 2010 it was the first temporary free-standing showroom building in Pattaya, which extended beyond the specified 9-meter limit. It is a 23 meter tall steel frame structure with concrete blanks and reinforced concrete deck. The basic idea behind this project was to present apartments with guaranteed sea views that are located at the same height and position as in the actual Wong Amat Tower.

Buildings and interior in Pattaya designed by the architect Mario Kleff - and what has changed until completion.

In Pattaya it is common to start with a design to change it later during the construction period. Mario Kleff ® do not welcome this approach. See some buildings and interior that have changed from the initial design to completion.

Moments in time

In pre-2010 Mario Kleff was on every advertising board, on radio, on television and in every magazine in Pattaya with his architectural designs, his daughter Jiang Li Wongsin was shown on the front page of The Pattaya Property & Lifestyle Magazine, with the headline New Generation of Creative Engineering. Architect Mario Kleff received official approval for the construction with integrated 20 to 41 meter long cellular beams and post-tensioned concrete deck for the Club Royal Condominium complex. The supporting engineer is Thai professor Somsak Khumplew.

However, the original concept of Club Royal Condominium complex has changed and the first official residential building with cellular beam and post-tensioned concrete deck is Park Royal 2 Condominium 2008-2010. These were wild times in Pattaya with cutting edge design and construction.

After Mario Kleff was celebrated an international star architect * in 2010, he later disappeared in 2017... and started in 2022 with real estate development in Pattaya From the beginning of 2021 to the end of 2022, the architect Mario Kleff designed 17 new villas and houses!
* Due to the fact that both projects in New York and Moscow were discontinued in 2011, the claims of an international star architect have also vanished.

Biography book Mario Kleff - Without Fear

Mario Kleff cuts an unconventional figure in the echelons of the real estate business in Thailand. Originally from Germany, the story of the man began in Bang Khun Thian, one of 50 districts Bangkok, Thailand. Without money and with just a bamboo hut as a home, Mario Kleff found a livelihood by selling coconuts in a longtail boat on the water channels to Bangkok. Within a few years, he became a millionaire and a recognized architect on the Eastern Seaboard.

Mario has, indeed, a fascinating character; a driven individual who knows what he wants and generally knows how to get it. His sheer will and commitment leads to its own way in privacy and in business. He prefers a companionship of leopards rather than a common family life. He builds up his own cars and motorcycles and stands the consequences of an uncompromising and creative lifestyle. Mario Kleff was born into a middle-class family with an aristocratic background. His motto: Express yourself without fear ...

Mario Kleff – Investing for success

... I was only interested in up-market projects because they gave me the scope to put my personal stamp on them. I welded steel plates to the beam and foundation with my name and date of creation, he said. I wasn’t able to do that with mid-market or budget priced housing because there was no design challenge involved in them. It wasn’t possible to achieve anything special because of budgetary constraints. The need to be individual, perhaps even unique, was so important to Mario that he took on a villa project only if he was given an entirely free hand to design what he liked. The owner’s job was to stipulate what he wanted the property to consist of and no more. The structure was up to Mario.

By the end of 2007, the Wandeegroup had around 100 construction workers on the payroll in addition to its office staff. Mario Kleff knew that the key to achieving what he wanted on site was having the right people in charge, so he chose three foremen who he personally trained in his own, inimitable way. Each had a car, a salary, and the motivation of a percentage of the profits from the projects under their control. They were trained in the same strict manner I had used with my office staff, said Mario. I earned their respect and loyalty by being tough. They quickly learned that they were to take orders from nobody but me. We drank together, celebrated together and, on occasions, I set aside the fact I was the boss and we fought together. They called me crazy, as did my office staff, but it achieved results that they could share in.

By the end of 2009, Mario Kleff and his Wandeegroup had designed between 30 and 40 apartment buildings, including individual structures like the Leto, View Talay, South Beach Boutique Chic, I-Condominium, On The Hill, Domum, Maraka, Laguna Bay, Laguna Heights and The Cube. But there were also more complex developments on the drawing board like The Wave with 2 buildings, Park Royal Series, consisting of 4 buildings, and the Club Royal with 5 buildings for Heights Holdings Co Ltd managed by CEO Haim Bar-David. The Club Royal was subjected to three complete redesigns including new building permits, said Mario, somewhat grimly. Mario Kleff also designed the Suan Sawarn complex of 13 buildings, the largest condominium resort of the TAG Development Group, under the direction of Gordon Keith Gillen. The development of Suan Sawarn consisted of four phases. The architectural design and the master plan of Suan Sawarn phase 1 remain and can be regarded as new development The Ivy Jomtien.
