>> Fast facts about Mario Kleff and information on the best architect in Pattaya.

From an arts student to Wandeegroup CEO

In the 1990s, Mario Kleff moved to Bonn for the first time and later to Munich to pursue a career in fine art and design, followed by a series of exhibitions with his replicated pages in original techniques from the Book of Kells. His intention to copy the "uncopimentable" Book of Kells brought him to the attention of the public and earned him widespread recognition Pádraig Murphy, Ambassador of Ireland, and Canon Prälat Prof DDr Franz Ronig, expert on illuminated manuscript and governor of Pro Libris e.V.[1]

Together with the Urs Graf Verlag Bern and Urs Düggelin, publisher of Faksimile Verlag Luzern in Switzerland, Mario Kleff exhibited five of his folios of the Book of Kells in the Gutenberg Museum, located in the old town of Mainz.[2] The exhibition "Irland und das Book of Kells" with curator Dr Adold Wild took place in February 6 - April 12, 1993.

Mario Kleff's work was later exhibited under the theme "Glanz Des Mittelalters" - October 27 - November 2, 1997 - in the Diocesan Museum in Trier.[3] The exhibition was curated by Prof Dr Michael Embach. This was followed by a Germany-wide traveling exhibition until 2001.[4]

From 1990 to 1997 Mario Kleff created over 40 folios of the book Kells with original techniques and colors of precise recipes.[5] Mario Kleff received a copy of the original Facsimile Book of Kells from Urs Düggelin for further study and exhibitions.[6] In 1990, the price for one of the 1,480 Verlag copies, composed of two volumes – the facsimile itself and a scientific commentary – was IR£7,000 (€8,888).[7]

During art studies from 1990 - 1992 Mario Kleff lived with the permission of Countess Uta von Bassewitz and Cornelia von Guilleaume, daughters of Herwart von Guilleaume, in the Villa Haus Herresberg at the banks of the Rhine near Remagen. With the permission of Baroness Tilla von der Goltz and Busso von der Dollen, German Castles Association, and supported by arts administrator Gabriele Fischer from Obernhof, Mario Kleff regularly created calligraphy reproductions of the Book of Kells in the Marksburg from 1990-1994.

At the beginning of 1992, Mario Kleff worked as a photography student for a short time with Ralf Häselich Arts Unlimited located in a locomotive hall in Mayen, Germany. After, and for the coming four years, studying in art, history, design and architecture was on the program. After the fall of the Berlin Wall, Kleff also worked as a techno-DJ in East-Berlin and spent time producing art in Goa, India and Ko Pha Ngan, Thailand.

Mario Kleff's career was expanded in 1996 by the event of new media. Kleff was critically acclaimed and in 1997 initially became art director under Klaus Beckmann in the AGW — Gesellschaft für Werbung und Public Relations, and later under Walter Hiel in Hiel/BBDO Munich. BBDO is one of the largest advertising agencies with a worldwide network and headquarters in New York. Over the years, Mario worked as an art director under Harald Schleer at AD. VENTURE Werbeagentur GmbH and under Michael Sametinger at Samt and Rosen. As in part time, Mario Kleff worked as a stage designer in Berlin, Cologne and Munich and has designed as a freelance art director editions of the GEMA magazine and the Vogue.

Another company Kleff worked for is Hakuhodo Inc. It is Japan's second largest advertising agency and recognized worldwide as one of the leading public relations firms. Mario Kleff was appointed creative director by Mr Tachikawa for the establishment of a new branch in Munich, Hakuhodo (Germany) GmbH. In the same year, the new Econ AG Wiesbaden (Germany) offered Mario Kleff a position as creative director for the new branch in Munich. Mario kleff oversaw the marketing mix and graphic arts; but received harsh feedback for controversial performance art. In 1999, visitors in the Mario Kleff exhibition in the Aktionsforum Praterinsel on Prater Island Munich, voluntarily donated blood samples for a screen printing. The curator was Erno Vroonen. The performance art 'Art Is Dead, Yet Alive' was repeated at Vienna, Stephansplatz. The young man Mario Kleff challenged the art world with 'Art Is Dead', 'Do Ut Des' and 'Human Being Is Art'.

'Art Is Dead' began when Mario Kleff rejected the literature he had acquired over the years and manifested himself in a ritual burning of the books and painted the words 'Art Is Dead' in red and exhibited it at the art college RSKA in Hennef towards the end of 1993. Mario’s desire to cast out the old was deep-seated. He believed that the paintings of the old master could only be copied, never be new created; The same with the music he heard was created by composers who died long ago.

In the late 1990s, Mario Kleff developed the idea for an elaborate and experimental performance when he designed wrapped mannequins, who presented a man, a woman and a child who were bandaged in steel cages and set on fire. Each mannequin consisted of eighty percent water, which was stored in small plastic bags. While the mannequins burned, some water flowed through funnels at the bottom of the cages under which were placed 1/2 gallon glass containers, labeled 'Human Being Is Art'. The sound of heartbeats recorded over a microphone attached to the chest of Mario Kleff, and live techno music created an environmental declaration performance and the begin of 'Art Is Dead, Yet Alive'. In part 2, Mario Kleff mixed the blood drawn from visitors to his performance and created the painting Do Ut Des ('I give that you might give') expressing the reciprocity of exchange between human being and deity, reflecting the importance of gift-giving as a mutual obligation in ancient society and the contractual nature of the religion in ancient Rome. The performance came to an end when a crane raised a steel structure in the form of a picture frame to portray a human as a picture. Illuminated with anti-aircraft searchlights, Kleff was at the height of about 30 meter with his message 'Human Being Is Art'.

Years In Thailand

In early 2002, still a young man, Mario Kleff moved to Bangkok (Thai: กรุงเทพมหานคร, RTGS: Krung Thep Maha Nakhon, pronounced [krūŋ tʰêːp mahǎː nákʰɔ̄ːn] (Play sound listen)), the capital of Thailand. After living some time in Bang Khun Thian (Thai: บางขุนเทียน, pronounced [bāːŋ kʰǔn tʰīa̯n] (Play sound listen)) in his first built bamboo hut and sold coconuts with a longtail boat (Thai: เรือหางยาว, RTGS: Ruea hang yao, pronounced [rɯ̄a̯ hǎːŋ jāːw] (Play sound listen)) on the river. After a simple life of over two years, he wanted to learn more about the language and culture of Thailand...

Kleff moved on in 2004 to Pattaya (Thai: พัทยา, RTGS: Phatthaya, pronounced [pʰát.tʰā.jāː] (Play sound listen)) in the Chonburi (Thai: ชลบุรี, RTGS: Chon Buri, pronounced [tɕ͡ʰōn bū.rīː(Play sound listen)) province. Within the first year Kleff founded his architecture firm and the associated construction company Wandeegroup (Thailand) Co Ltd and built his office at 162/220, Thappraya Road, Bang Lamung District (Thai: บางละมุง, pronounced [bāːŋ lā.mūŋ] (Play sound listen)).

In the following year, in April 2005, Mario Kleff married Thai Chinese Nittaya Wongsin at the Buddhist temple Wat Yannasangwararam (Thai: วัดญาณสังวรารามวรมหาวิหาร, RTGS: Wat Yannasangwararam, pronounced [wát jaːnnáʔsǎŋwáʔraːraːm] (Play sound listen)), in short: Wat Yan. Since such celebrations are not allowed in a Royal Temple for common Thai people and foreigners, it was the first wedding ceremony in the history of Wat Yan.[8] Mario Kleff received special permission for this ceremony from the head abbot because of his artistic lifestyle, his thoughts in Buddhism and the time he spent in Bang Khun Thian – another important part of the man's biography.

Pride and disappointment — common in a creative lifestyle

In 2004 - 2015 Kleff's company Wandeegroup delivered a blend of new architectural design and structural engineering in Pattaya and continued business opportunities for real estate development in Thailand and abroad. In the years 2007 - 2018, the architect Mario Kleff designed nine skyscrapers with heights of 130 to 278 meter, and designed over fifty 8 story apartment blocks and numerous homes and pool villas.[Retrieved] Kleff's designs were approved by the relevant construction departments. The construction work for only two of the skyscrapers have begun or are completed.

In 2006, Mario Kleff was invited by Pichet Uthaiwattananota, Head of the Construction Department of Pattaya City Hall from 2006 - 2011, to present ideas for the modernization of Pattaya Beach. In a competition, Kleff proposed a museum designed in the form of a modern concrete structure to be erected in the sea to honor King Rama IX / Bhumibol Adulyadej (Thai : ภูมิพลอดุลยเดช, RTGS: Phumiphon Adunyadet, pronounced [pʰūː.mí.pʰōn ʔā.dūn.jā.dèːt] (Play sound listen)), who was an avid sailor and a boot designer.[9] The project included a scale model and was later exhibited in the Pattaya City Hall. Mario Kleff also designed a bridge for pedestrians, including a welcome structure for Pattaya City. The construction costs were declared unacceptable and the idea put on hold.

In 2018, the man's biography was further enhanced... Mario Kleff (Thai name: Bhumeth Issarasilp) and his Wandeegroup was put into operation to redesign a mega project, the Thakhek Dream World City, worth five skyscrapers with heights of up to 278 meter, including a shopping complex[10] [11] [12] [13] on a plot of 7 hectare of land in Thakhek (Lao: ທ່າແຂກ (Play sound listen)), Laos. Kleff has completed the designs at the beginning of 2019. The project is on hold since 2020.

In 2018 and into 2019, Mario Kleff has designed a hospital on 11 hectare of land, and a rehabilitation facility including lake, public buildings, hotel, library, sports arena, spa and meditation spaces and over 80 villas on 28 hectares of land in the Nakhon Ratchasima Province (Thai: นครราชสีมา, pronounced [ná(ʔ).kʰɔ̄ːn râːt.t͡ɕʰā.sǐː.māː] ( Play sound listen)), often called Khorat (Thai: โคราช, pronounced [kʰōː.râːt] (Play sound listen)) (alternate spelling Korat) for Her Royal Highness Princess Chulabhorn (Thai : สมเด็จพระเจ้าน้องนางเธอ เจ้าฟ้าจุฬาภรณวลัยลักษณ์ อัครราชกุมารี, (Play sound listen)) and the Chulabhorn Research Institute under the patronage of Major General or Air Vice-Marshal Dr Santi Srisermphoak (Thai: พล.อ.ต.นพ.สันติ ศรีเสริมโภค, (Play sound listen)), pictured. The project was discontinued in 2019.

The support of a few is sufficient to start the engine

With a mix of creativity and knowledge, Mario Kleff did not only push the boundaries in Pattaya in the field of architecture, but also in engineering. He introduced innovative structural engineering solutions including the cellular beam[14] in the local construction industry and in Thailand. The cellular beam is a newer version of the castellated beam. The integration of cellular beam in residential construction required support from the authorities of local construction departments. For his innovative ideas and commitment Kleff received a Letter of Recommendation[15] for PhD in architecture from Pichet Uthaiwattananota (Thai: พิเชษฐ อุทัยวัฒนานนท์, (Play sound listen)) Head of the Construction Department Pattaya City from 2006 - 2011.

Mario Kleff in a meeting with AVM.Dr Santi Srisermphoak (center) held in Thailand's Northern province Chiang Mai (/ˌtʃæŋ ˈmaɪ/, from Thai: เชียงใหม่ [tɕʰīəŋ màj] (Play sound listen)). Concept and plans for a new Thai rehabilitation facility in Korat were discussed. The project development was led by SG.Prof Nithi Mahanonda and AVM.Dr. Santi Srisermphoak. Mario Kleff is the architect and presented the project.

Mario Kleff is a man who believes in himself. With confidence and focus he offers state-of-the-art engineering skills, advanced technical back up and in-depth knowledge of design standards for any type of building. Kleff creates architecture structures starting with a master plan to interior design, and includes building technologies and systems that make the building well. Mario Kleff is a German architect who is allowed to work in Thailand as a building designer, engineering consultant and construction supervisor.[16] Work check leading to planning permission is carried out by Dr Songkiat Matupayont, an advanced engineer from Bangkok who works with Kleff on new inventions and state of the art construction designs. Songkiat Matupayont recommended Mario Kleff for an honorary doctorate in engineering for his work on Park Royal 2 and The Touch® in 2011. The universities in Bangkok could not accept Kleff due to a lack of Thai citizenship.

It was not until 2016 that Kleff was granted Thai citizenship and a new identity as Bhumeth Issarasilp.[17] Mario has changed his new name later in Thiti Teerachin (Thai: ธิติ ธีรชินทร์), and in June 2021 founded a new architecture and construction company, Wandeegroup Asia Co Ltd. Architect Mario Kleff won two new villa projects in the same month; [18] [19] [20] one of the 2 story villas designed by Mario Kleff is with a 48 meter long-span cellular beam[21] between two columns to support a post-tensioned concrete slab - a new record in the local construction industry.

Kleff was successful as a creative consultant for real estate developments, but also had several disappointments. Some large real estate developments and structures designed by Mario Kleff were not realized on the construction site. Also many buildings have changed during the construction in their overall appearance. Kleff never abandoned to find a new challenge in design and technology. In May 2022 he was commissioned to develop six luxurious pool villas with his Wandeegroup Asia. Mario Kleff opted for long-span beams and post-tensioned concrete structure. His newly founded company Wandeegroup Asia is now building seven luxury villas and already has the first mid-rise building on the drawing board. After more than 10 years of experience with post tensioning concrete and the construction of long span structures, Mario founded an additional company in July 2022 that specializes in this field - Wandee Super Span ™ Co Ltd. The company started out with two residential projects, one of which integrates 30 meter long concrete girders, one with post-tensioned footings presented for the first time in Pattaya.

Notable architecture in Pattaya designed by Mario Kleff

Mario Kleff together with developer Heights Holdings CEO Haim Bar-David and Wandeegroup (Thailand) construction worker on the Wongamat Tower construction site in Pattaya

At the Wong Amat Tower construction[23] site in Pattaya (Thai: พัทยา, RTGS: Phatthaya, ;pronounced [pʰát.tʰā.jāː] (Play sound listen)), Mario Kleff, Heights Holdings CEO Haim Bar-David, and Wandeegroup workers are pictured together on a steel girder, ready to start construction of the exhibition building Showroom Wong Amat Tower[Sig.].

High-rise building Wong Amat Tower

The Wong Amat Tower, commonly known as Wongamat Tower, is a single, 38 story structure with 361 units that was completed in 2015. It is located in Pattaya Nuea. Mario Kleff designed the building in 2008[22], which included comprehensive planning, structural drawing, the use of cellular beam, and modular design. Later, the original steel frame was remodeled, and reinforced concrete columns and post-tensioned slabs took its place.[24] Wong Amat Tower is Mario Kleff's first high-rise tower completed.
The building's design is protected by the copyright of architect Mario Kleff, who has granted the developer Heights Holdings to make alterations in 2011.[25] The building's wide-span design and earthquake-resistant structure are notable characteristics.

High-rise building Mario Kleff - The Touch ®

On Phra Tamnak Hill in Pattaya, The Touch ®, a 33 story high-rise, was developed as both a statement and a landmark.[26] With just two pillars supporting the tower and a clear construction span of 25 meter between the pillars, it is the highest building permitted at this location and the first high-rise building with two columns in Thailand. Mario Kleff is the project's designer and developer.[27] Construction started in December 2011 after obtaining the planning permit.[28] Later on, before the tower was completed, the project was sold. Andromeda is the project name of the new tower constructed over this base.

The Touch ® has the following features: a glass façade, two reinforced hollow-core concrete columns that support the structure, cellular steel box girders that span 25 meter between columns, an unobstructed view of the sea, ceiling heights of 4 to 9 meter, and it is earthquake-proof. Because it allows users to operate the building's systems using a smartphone, the structure is known as Touch ® and the app was created by Mario Kleff in 2010.

Park Royal 2 apartment building

Park Royal 2 consists of a single, 85-unit building with nine stories that was completed in 2011. It relates to the Park Royal Series 1, 2, and 3, and Laguna Bay 1+2. The use of cellular beam and post-tensioned concrete, is a notable design.

Japanese House

The Japanese House II Phra Tamnak Hill, a single 2 story structure that was completed in 2009, is a villa with long span, cantilever, extensive use of concrete and steel, and more than a hundred bored piles designed by architect Mario Kleff.[29]

Park Royal 2, designed in 2008 by Mario Kleff, is a 8-storey apartment building - built with cellular beam combined post-tensioned concrete slab 24x27 meter.

Designed in 2008 by Mario Kleff, Park Royal 2, is an eight-story apartment complex that was constructed using steel frame and cellular beams, a more sophisticated version of the castellated beam, along with a 24x27 meter post-tensioned concrete slab. The construction method of Park Royal 2 was the first permitted in Thailand.

Design Hallmarks

For the young guy Mario, modern architecture and Bauhaus in Germany was the most inspiring type of architecture. He admired the design and concept of building a clean environment and infrastructure. Mario Kleff studied Asian aesthetics and modern Japanese architecture in addition to receiving a classical education in history and the foundational design lessons of the ancient masters of architecture, music, and art. Currently, Mario Kleff specializes in brutalist and minimalist architecture, and his name is a registered trademark in both those fields.

Kleff acquired a foundational understanding of Japanese design philosophy and mathematics in the early 1990s. Later on in Japan, Mario Kleff furthered his understanding of ZEN design and Japanese architecture. The Villa Futureproof, a blend of German engineering expertise and Japanese design philosophy, was Kleff's first building in Thailand in 2004.
2020 had seen the sale of Mario Kleff's minimalist brutalist design for an opulent seaside home close to Cape Town, which included eight 60-meter-long post-tensioned concrete girders. In 2022, construction on this project has not yet begun.

The Koi House, the Falling Rain, the Japanese House I and the Japanese House II are some of Mario Kleff's earliest structures. The Wing House, with which Kleff revolutionized the Pattaya real estate industry in the early 2000s by introducing steel beams, exposed concrete, and glass facades, is shown below. The Pattaya developers have only approved a few number of contemporary multi-story structures, such as Park Royal 1, Park Royal 2, Park Royal 3, and Club Royal Condominium, as marketable residential property developments. During the construction process, most plans have changed.

Exposed concrete villa Wing House

Quote by Mario Kleff: I am most against decoration. A statement that arose after he performed 'Art Is Dead', 'Do Ut Des' and 'Human Being Is Art' in 1997 and after working with BMW, Germany, as an art director till 2000.

Furniture design and interior decorating

The architect Mario Kleff doesn't believe in making compromises when it comes to the presentation of the finest materials; instead of making restorations and decorating, he designs unique furniture and interiors. Concrete, stone, steel, and solid wood are all used extensively.[30]

Construction design and engineering

Real estate projects designed by Mario Kleff never miss in stability or extravagance.[31] The defining feature and hallmark of all Wandeegroup projects over the years has been the extensive usage of concrete and steel. Box girders, hollow-core concrete slabs, post-tensioned decks, and anything used above a bridge's main deck, like steel truss systems, prefabricated prestressed concrete structure, stay cable systems, cable suspension systems, etc., are components used in bridge construction and, in the opinion of customers, can be seen in villas built by his construction company Wandeegroup.

To build expansive, column-free living spaces, Mario Kleff prefers to use large steel girders and post-tensioned concrete beams. Some of Kleff's architectural solutions feature cantilevers that extend farther than 20 meter. Other structures with a height of more than 50 meter with only one support column. A luxury pool villa with a sea view of up to 80 meter from the living room can be ordered by the architect Mario Kleff.

Architecture visualization and design presentation

Mario Kleff is a specialist in 3D and virtual design. From the late 1990s, Kleff has produced 2D/3D design and VFX on Apple Macintosh and PC. To provide his clients the finest presentation possible, he now uses Unreal Engine, Houdini, Autodesk Maya, Autodesk 3ds Max, Solidworks, Rhinoceros 3D, Autodesk AutoCAD, Autodesk Revit and Autodesk BIM 360. During his time as a television station's art director, Mario Kleff has been familiar with the Quantel Paintbox Workstation. [ Scroll to page top ]

Mario Kleff uses premium materials for manufacture and finishing, including titanium, aerospace aluminum, magnesium, metal matrix composite and carbon fibers. [ Scroll to page top ]

Architect Mario Kleff leads a high performance lifestyle[32], which calls for high-performance vehicles. Over many years, Kleff created a variety of extreme custom cars and custom motorcycles, as well as internal combustion engines that were produced as needed. Parts and automobile engines with displacement up to 15,000 cubic centimeter (symbol cm³ or cc) and up to 1,700 horsepower[33] as well as motorcycle engines with displacement up to 3,700 cc and up to 1,000 hp were supplied by engine producers in the USA, Italy, England, and Germany. Mario Kleff created the chassis, body, wheels, and brakes to provide handling and secure driving. From computer-aided design (CAD) drawings and computer-generated imagery (CGI) rendering to CNC machining and welding in the workshop, Kleff produced one-of-a-kind vehicles.


In recent years Mario Kleff has also developed distinctive and potent scooters including Vespas with V2 turbo engines with 2,540 cc displacement, Mod Dam (Thai: มดดำ, ( Play sound listen)), a Honda MSX with a new engine supplied by one of the best motorcycle developers Ducati Corse with its flagship Panigale 1199 R and a Honda Zoomer with almost 800 hp on the rear wheel powered by a custom turbo charged Hayabusa engine, namely the Super Mario, built by Big CC Racing, it is probably the most powerful minibike in the world.

Life With Leopards

Mario Kleff in 2019 with his male leopard Typhoon.

Mario Kleff and Typhoon, a male leopard, in 2019. 'I experience the most priceless connection life has to give,' he remarks. 'Based on an unfathomable amount of trust and affection, Fasai and Typhoon have a bond with me. Yet it also comes with restrictions and responsibility.' It hasn't been simple for Mario Kleff and his family to express their ownership rights.[36][37]

Mario Kleff and the leopards Fasai and Typhoon

The most significant aspect of Mario Kleff's biography may be his encounters with wildlife as a child when living in Libya and Chad, as well as in the 1990s in Maharashtra. It created such a lasting impression that Mario Kleff went on to frequently visit zoos after that, but he did it inside the housing with the wild cats rather than in front of the fence.

Mario Kleff spent a lot of time with the leopards and jaguars that have special meaning for him. Around 2000, other occurrences in India would influence Kleff's concern in protecting leopards.

Mario Kleff, the architect, saw the birth of two leopards in Thailand in 2015; he later named them Fasai and Typhoon. Shortly after birth, a decision had to be taken regarding how to care for these infant creatures because time and responsibility would have an impact on daily operations. Fasai and Typhoon will be cared for by Mario Kleff after his decision to adopt them. Since then, the two leopards have shared Kleff's home, office, and outdoor space as legal companions.[34][35] View more than 60 photos Fasai and Typhoon.

In addition to sending a team of Wandeegroup employees to South Africa for training and in-depth information on how to handle leopards in domestication and healthcare, Kleff gave Fasai and Typhoon with a personal veterinarian who specialized in big cats. The architect Mario Kleff spent 13 months without walls, a kitchen, a bedroom, or a bathroom in Thailand's northern mountain and forest region in order to make the most of their existence. Nittaya Wongsin, Kleff's wife, who frequently dropped by in the morning and during the day, provided the food for Mario. For the period of 2015 to 2018, Kleff shut down the construction company Wandeegroup (Thailand) Co Ltd, and his Pattaya architecture office. [ Scroll to page top ]
