Early Life and Educational Background

In the early 1990s, Mario Kleff, originally from Bonn, moved to Munich pursuing a career in fine art and design, caught the public's attention with his intricate replicas of the Book of Kells. His endeavors earned him praise from the likes of Pádraig Murphy, Diplomat of Ireland, and Canon Prälat Prof DDr Franz Ronig, a renowned expert on illuminated manuscripts.[1]

In collaboration with Urs Graf Verlag Bern and Urs Düggelin, publisher of Faksimile Verlag Luzern, five of Kleff's Book of Kells folios were displayed at the Gutenberg Museum, Mainz.[2] during the "Irland und das Book of Kells" exhibition from February 6 to April 12, 1993, curated by Dr. Adold Wild.

His work was further showcased in the Diocesan Museum in Trier under "Glanz Des Mittelalters" from October 27 to November 2, 1997.[3] Prof Dr. Michael Embach curated the exhibit, which later transformed into a traveling exhibition across Germany until 2001.[4]

Between 1990 and 1997, Kleff crafted over 40 folios of the Book of Kells using authentic techniques and color recipes.[5] In acknowledgment of his efforts, he received a facsimile of the Book of Kells from Düggelin.[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]

While studying arts from 1990-1992, Kleff resided at Villa Haus Herresberg at the banks of the Rhine near Remagen, courtesy of Countess Uta von Bassewitz and Cornelia von Guilleaume. He also worked on calligraphy reproductions at the Marksburg, with the support of the German Castles Association represented by Baroness Tilla von der Goltz and Busso von der Dollen.

Kleff briefly collaborated with Ralf Häselich Arts Unlimited located in a locomotive hall in Mayen in 1992. Following the fall of the Berlin Wall, his pursuits led him to work as a techno-DJ in East-Berlin and to produce art in locations like Goa, India, and Ko Pha Ngan, Thailand.

Kleff's professional horizon broadened in 1996 with the dawn of new media. He served as an art director at several prestigious firms, including AD. VENTURE Werbeagentur GmbH, AGW, Samt and Rosen, adNET Werbeagentur GmbH, and Hiel/BBDO Munich. BBDO is one of the largest advertising agencies with a worldwide network and headquarters in New York. Concurrently, Kleff's talents were employed in stage design across German cities and as a freelance art director for notable magazines like GEMA and the Vogue.

His expertise was later recognized by Hakuhodo Inc., Japan's second-largest advertising agency and recognized a leading public relations firm. He was appointed as the creative director by Mr Tachikawa for their new branch in Munich. New Econ AG Wiesbaden (Germany) offered him a position as the creative director for the new branch in Munich, in the same year. Kleff oversaw the marketing mix and graphic arts. However, Kleff's ventures weren't without controversy; a 1999 performance art piece in the Aktionsforum Praterinsel on Prater Island, where visitors donated blood for screen printing raised eyebrows. His provocative art like 'Art Is Dead', 'Do Ut Des' and 'Human Is Art' posed challenges to conventional art perspectives.

Art performance Art Is Dead

Mario Kleff's provocative statement, "Art Is Dead", emerged from a profound disillusionment with the literature he had amassed over the years. In a symbolic gesture, he ritually burned these books and, using bold red paint, articulated his sentiment on canvas. This work was then showcased at the RSKA college in Hennef in late 1993. At the heart of this act was Kleff's conviction that the masterpieces of yesteryears could merely be replicated, not reinvented afresh. Similarly, he felt the music that resonated with him was largely the legacy of long-deceased composers.

Venturing deeper into the 1990s art philosophy, Kleff conceived an intricate and avant-garde performance. He crafted mannequins symbolizing a man, woman, and child, wrapping them in bandages and confining them in steel cages, which were subsequently ignited. Intriguingly, these mannequins were 80% water stored in petite plastic sachets. As they were consumed by flames, water trickled down funnels located at the cage's base, collecting in glass containers inscribed with 'Human Being Is Art'. This scene was set to the backdrop of heartbeats, captured via a microphone on Kleff, harmonized with live techno beats. This marked the inception of 'Art Is Dead, Yet Alive' - Essence of art.

In a subsequent act, Kleff used blood, voluntarily donated by attendees, to craft a painting titled Do Ut Des — Latin for ('I give that you might give'). This artwork underscored the ancient societal principle of mutual gift-giving and mirrored the transactional essence of religion in ancient Rome. Culminating this evocative performance, a crane elevated a steel construct resembling a picture frame, encapsulating a human figure. Illuminated majestically by searchlights, Kleff, elevated approximately 30 meters above, broadcasted his profound message: 'Human Is Art'.

Years In Thailand: Bangkok to Pattaya

In early 2002, a young Mario Kleff relocated to Bangkok (Thai: กรุงเทพมหานคร, RTGS: Krung Thep Maha Nakhon, pronounced [krūŋ tʰêːp mahǎː nákʰɔ̄ːn] (Play sound listen)), the vibrant capital of Thailand. For a period, he resided in Bang Khun Thian (Thai: บางขุนเทียน, pronounced [bāːŋ kʰǔn tʰīa̯n] (Play sound listen)), where he constructed his first bamboo hut. He also sold coconuts using a longtail boat (Thai: เรือหางยาว, RTGS: Ruea hang yao, pronounced [rɯ̄a̯ hǎːŋ jāːw] (Play sound listen)) on the river. After living this modest life for over two years, his curiosity about Thai language and culture grew, prompting him to immerse himself further into the heart of Thailand.

In 2004, Kleff relocated to Pattaya (Thai: พัทยา, RTGS: Phatthaya, pronounced [pʰát.tʰā.jāː] (Play sound listen)). It is located in the Chonburi (Thai: ชลบุรี, RTGS: Chon Buri, pronounced [tɕ͡ʰōn bū.rīː(Play sound listen)) province. Within his first year there, he established his architecture firm and its corresponding construction company, Wandeegroup (Thailand) Co Ltd. He built his office at 162/220 Thappraya Road, in the 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 renowned Buddhist temple Wat Yannasangwararam (Thai: วัดญาณสังวรารามวรมหาวิหาร, RTGS: Wat Yannasangwararam, pronounced [wát jaːnnáʔsǎŋwáʔraːraːm] (Play sound listen)). Commonly referred to as Wat Yan, this temple holds significance as a Royal Temple. Notably, this was the first wedding ceremony ever to take place at Wat Yan. Typically, such ceremonies are not permitted for ordinary Thai citizens and foreigners.[8] However, Mario Kleff was granted special permission from the head abbot due to his artistic contributions, his deep connection with Buddhism, and the significant time he spent in Bang Khun Thian, which is an integral aspect of his life story and another important part of his biography.

Pride and Challenges in a Creative Career

Between 2004 and 2015, Kleff's company, Wandeegroup, introduced a unique mix of modern architectural design and structural engineering in Pattaya, expanding business opportunities in real estate development both in Thailand and internationally. From 2007 to 2018, Mario Kleff, the architect behind the company, designed nine skyscrapers ranging from 130 to 278 meters in height.[AC1] He also conceptualized over fifty "eight-story" apartment buildings and a plethora of homes and pool villas.[Retrieved] "Although Kleff's designs received approval from the pertinent construction departments, construction began or was completed on only two of the skyscrapers."

In 2006, Pichet Uthaiwattananota, who led Pattaya City Hall's Construction Department from 2006 to 2011, invited Mario Kleff to share ideas for revitalizing Pattaya Beach. In a design contest, Kleff suggested a sea-based museum as a contemporary concrete tribute to King Rama IX/Bhumibol Adulyadej (Thai : ภูมิพลอดุลยเดช, RTGS: Phumiphon Adunyadet, pronounced [pʰūː.mí.pʰōn ʔā.dūn.jā.dèːt] (Play sound listen)).[9] Bhumibol was a passionate sailor and boat designer. This project proposal, complete with a scale model, was later showcased at Pattaya City Hall. Additionally, Kleff proposed a pedestrian bridge featuring a welcoming landmark for Pattaya City. However, the projected construction costs were deemed too high, and the project was subsequently shelved.

2018 marked another significant chapter in Kleff's biography. Operating under his Thai name, Bhumeth Issarasilp, he and his Wandeegroup were commissioned to re-envision a significant project — Thakhek Dream World City in Laos. This mega-project comprised five skyscrapers, reaching up to 278 meters, accompanied by a shopping complex[10] [11] [12] [13] on a 7-hectare of land in Thakhek (Lao: ທ່າແຂກ (Play sound listen)), Laos. Kleff completed the project's designs at the onset of 2019. However, as of 2020, the project has been put on hold.

During 2018 and 2019, Mario Kleff crafted designs for a hospital spanning 11 hectares and a rehabilitation center encompassing amenities such as a lake, public structures, a hotel, library, sports stadium, spa, meditation areas, and over 80 villas spread across 28 hectares. This project, located in the Nakhon Ratchasima Province (Thai: นครราชสีมา, pronounced [ná(ʔ).kʰɔ̄ːn râːt.t͡ɕʰā.sǐː.māː] ( Play sound listen)), also known as Khorat, (Thai: โคราช, pronounced [kʰōː.râːt] (Play sound listen)) (alternate spelling Korat), was for Her Royal Highness Princess Chulabhorn (Thai : สมเด็จพระเจ้าน้องนางเธอ เจ้าฟ้าจุฬาภรณวลัยลักษณ์ อัครราชกุมารี, (Play sound listen)) and the Chulabhorn Research Institute, overseen by Major General or Air Vice-Marshal Dr. Santi Srisermphoak (Thai: พล.อ.ต.นพ.สันติ ศรีเสริมโภค, (Play sound listen)). However, the initiative was halted in 2019.

A few key Supporters can ignite Great Change

Mario Kleff, with his unique blend of creativity and expertise, revolutionized both architectural and engineering fields in Pattaya. He brought pioneering structural engineering solutions like the cellular beam — an evolved version of the castellated beam — to both the local construction landscape and the broader Thai industry.[14] Implementing the cellular beam in residential structures demanded support from local construction authorities.
Recognizing his groundbreaking contributions and dedication, Kleff was honored with a Letter of Recommendation[15] for a PhD in Architecture by Pichet Uthaiwattananota, (Thai: พิเชษฐ อุทัยวัฒนานนท์, (Play sound listen)), the Head of the Construction Department in Pattaya City from 2006 to 2011.

In a collaborative meeting held in Chiang Mai (/ˌtʃæŋ ˈmaɪ/, from Thai: เชียงใหม่ [tɕʰīəŋ màj] (Play sound listen)), Thailand's Northern province, Mario Kleff discussed conceptual plans for a new rehabilitation facility in Korat with AVM. Dr. Santi Srisermphoak, who was prominently present at the center of the discussions. The project's development leadership came from SG. Prof Nithi Mahanonda and AVM. Dr. Santi Srisermphoak. As the architect behind the initiative, Mario Kleff showcased and presented the entire project.

Mario Kleff is a visionary, driven by unyielding self-belief. Armed with cutting-edge engineering expertise, robust technical support, and a profound understanding of design standards, he can cater to any architectural demand. From initial master planning to intricate interior design, Kleff integrates innovative building technologies and systems to ensure structural excellence. A German by origin with a work permit, he has earned the right to serve in Thailand as a building designer, engineering consultant, and construction overseer.[16] His collaborations with Dr. Songkiat Matupayont, a renowned engineer from Bangkok, have paved the way for planning permission for groundbreaking inventions and state-of-the-art construction designs. It was Dr. Matupayont who championed Mario Kleff for an honorary doctorate in engineering in 2011, in recognition of his exceptional contributions to projects like Park Royal 2 and The Touch®. However, universities in Bangkok were constrained from conferring this honor due to Kleff's citizenship status.

In 2016, Kleff was conferred Thai citizenship, adopting the new identity of Bhumeth Issarasilp.[17] He later renamed himself Thiti Teerachin (Thai: ธิติ ธีรชินทร์). By June 2021, he launched his new architectural and construction firm, Wandeegroup Asia Co Ltd. That same month, architect Mario Kleff secured contracts for two villa projects. [18] [19] [20] Remarkably, one of these two-story villas showcases Kleff's ingenuity with a 48-meter long-span cellular beam[21] situated between two columns, supporting a post-tensioned concrete slab. This feat set a new benchmark in local construction.

"While Kleff's prowess as a creative consultant for real estate is noteworthy, he has faced setbacks. Several expansive real estate developments and designs conceived by him never saw the light of day at the construction site. Many projects underwent significant changes during the construction phase. Undeterred, Kleff continually sought fresh challenges in design and technology. In May 2022, his firm, Wandeegroup Asia, was entrusted with the development of six opulent pool villas, employing long-span beams and a post-tensioned concrete structure. The burgeoning Wandeegroup Asia is currently constructing seven luxury villas and has initiated plans for a mid-rise building. Leveraging over a decade's expertise in post-tensioned concrete and long-span structure construction, Kleff inaugurated another specialized venture in July 2022: Wandee Super Span™ Co Ltd. Embarking on its journey with two residential endeavors, one of the projects boasts 30-meter long concrete girders, and the other introduces post-tensioned footings, a pioneering feat in Pattaya. The narrative of this dynamic individual unfolds..." [ Scroll to page top ]

1. Wong Amat Tower: Iconic Condominium Architecture

The Wong Amat Tower, often referred to as Wongamat Tower, is a towering 38-story edifice comprising 361 units, completed in 2015 and situated in Pattaya Nuea. Designed by Mario Kleff in 2008,[22] its architectural brilliance encompasses comprehensive planning, detailed structural drawings, innovative use of cellular beams, and a modular design approach. As the design evolved, the initial steel frame was revamped, making way for reinforced concrete columns and post-tensioned slabs.[24] This tower marks Mario Kleff's inaugural foray into high-rise constructions. While the building's design is under Mario Kleff's copyright, he granted Heights Holdings permission for modifications in 2011.[25] Distinguishing features include its expansive design and an earthquake-resistant structure.

2. The Touch® by Mario Kleff — A Signature On It's Own

Perched atop Phra Tamnak Hill in Pattaya, The Touch® is a striking 33-story skyscraper designed to be both iconic and monumental.[26] Its engineering marvel is showcased with two pillars holding up the structure and an impressive 25-meter construction span between these pillars, making it Thailand's pioneering high-rise of this design. As the brainchild of Mario Kleff, who served as both its designer and developer,[27] its construction was greenlit in December 2011.[28] However, before its completion, the project changed hands and was rebranded as Andromeda on the same foundation.

The Touch® is characterized by a sleek glass façade, reinforced hollow-core concrete columns, 25-meter spanning cellular steel box girders, uninterrupted sea vistas, variable ceiling heights ranging from 4 to 9 meters, and earthquake-resistant features. Its eponymous "Touch®" denotes a technological integration, allowing users to control building systems via a smartphone app, an innovation crafted by Mario Kleff in 2010.

3. Park Royal 2 Condominium

Part of the esteemed Park Royal Series, Park Royal 2 is a nine-story residential structure featuring 85 units, finalized in 2011. It's a sibling to Park Royal Series 1, 2, and 3, as well as Laguna Bay 1+2. Signature design elements encompass the employment of cellular beams and post-tensioned concrete.

4. Japanese House II

Situated on Phra Tamnak Hill, the Japanese House II is a two-story villa realized in 2009. Designed by Mario Kleff, its architectural signature lies in the extensive use of concrete and steel, long span design, of over a hundred bored piles.[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.

In 2008, Mario Kleff pioneered the design for Park Royal 2, an eight-story condominium building. This structure uniquely incorporated a steel frame combined with cellular beams — an advanced adaptation of the castellated beam — and featured a 24x27 meter post-tensioned concrete slab. Notable, the construction methodology deployed for Park Royal 2 received its inaugural permission for use in Thailand.

Legacy and Impact on Modern Architecture

From a young age, German modern architecture and Bauhaus deeply influenced Mario Kleff, drawing him into a world where clean, efficient designs held paramount importance. He greatly admired the clarity and precision required to create a streamlined environment and infrastructure. While he received a foundational education in history and fundamental design principles from ancient masters in architecture, music, and art, he also delved into the intricacies of Asian aesthetics and contemporary Japanese architecture.

Today, Mario Kleff's expertise lies predominantly in brutalist and minimalist architecture. Such is his prominence in these fields that his name is trademark in both.

In the early 1990s, Kleff immersed himself in Japanese design philosophy and mathematics. His time in Japan deepened his appreciation for ZEN design and traditional Japanese architectural styles. This confluence of influences culminated in the Villa Futureproof in 2004 — Kleff's maiden project in Thailand, which beautifully amalgamated German engineering prowess with Japanese design sensibilities.

The Distinctiveness of Mario Kleff Designs

In 2020, Kleff's visionary minimalist brutalist design for a lavish seaside residence near Cape Town was sold. This design boasted eight impressive 60-meter-long post-tensioned concrete girders. However, as of 2022, the actual construction remains pending.

Building Design Pattaya

Some of Kleff's initial architectural feats include the Koi House, Falling Rain, Japanese House I, and Japanese House II. Another notable project, the Wing House, reshaped Pattaya's real estate landscape in the early 2000s. With its innovative use of steel beams, exposed concrete, and glass facades, it stood as a testament to Kleff's groundbreaking visions. However, in Pattaya, only a handful of contemporary multi-story edifices, such as Park Royal 1, Park Royal 2, Park Royal 3, and Club Royal Condominium, have received approvals as viable residential property developments. It's worth noting that many original plans underwent significant alterations during the construction phase.

Exposed concrete villa Wing House

Quote by Mario Kleff: I am most against decoration. This sentiment emerged after his art performances, namely 'Art Is Dead', 'Do Ut Des' and 'Human Is Art', in 1997 and his tenure as an art director with BMW, Germany, until 2000.

Furniture Design and Interior Decorating

Architect Mario Kleff is uncompromising when showcasing superior materials. Instead of resorting to mere restorations and typical decorating techniques, he crafts distinctive furniture and interiors. His designs predominantly feature robust materials such as concrete, stone, steel, and solid wood.[30]

Combining Luxury and Functionality

Construction Design and Engineering

Stability and luxury are the hallmarks of real estate projects spearheaded by Mario Kleff.[31] A distinguishing trait of Wandeegroup ventures over time is the profound incorporation of concrete and steel. Components like box girders, hollow-core concrete slabs, post-tensioned decks, and structural elements seen atop bridges - including steel truss systems, prefabricated prestressed concrete structures, stay cable systems, and cable suspension systems - are prominently visible in villas crafted by Wandeegroup.

In his quest to create vast, column-free living areas, Mario Kleff leans toward utilizing expansive steel girders and prestressed concrete beams. Several of his innovative designs boast cantilever extending beyond 20 meters, while others are towering edifices, surpassing 50 meters in height, anchored by a singular supporting column. Through Kleff's visionary approach, clients can commission a luxury pool villa boasting panoramic sea vistas stretching as far as 80 meters from their living space.

Architecture Visualization and Design Presentation

With profound expertise in 3D modeling and virtual design, Mario Kleff has been a pioneer since the late 1990s. Leveraging both Apple Macintosh and PC platforms, he has excelled in producing 2D/3D designs and VFX. To offer his clientele unparalleled presentations, he proficiently utilizes tools such as the Unreal Engine, Houdini, Autodesk Maya, Autodesk 3ds Max, Solidworks, Rhinoceros 3D, Autodesk AutoCAD, Autodesk Revit, and Autodesk BIM 360. Mario's adeptness with the Quantel Paintbox Workstation was particularly honed during his tenure as an art director for a television network. [ Scroll to page top ]

In 2019, Mario Kleff is pictured alongside Typhoon, a male leopard, in 2019. He reflects, I've felt the most invaluable bond life can offer. With Fasai and Typhoon, there's a relationship rooted in profound trust and love. However, such a bond brings its own challenges and obligations. Fasai and Typhoon have a bond with me. Yet it also comes with restrictions and responsibility. Asserting their rights of guardianship hasn't been a straightforward journey for Mario Kleff and his family.[36][37]

Mario Kleff's Wildlife Bond: From Childhood Encounters to Fasai and Typhoon

Mario Kleff's profound connection with wildlife traces back to his early years spent in Libya and Chad, and later experiences in Maharashtra during the 1990s. These encounters left an indelible mark on him, compelling Kleff not just to visit zoos but to immerse himself in the housing, standing alongside wild cats rather than viewing them from behind barriers.

Leopards and jaguars hold a particularly special place in Kleff's heart. Around the turn of the millennium, experiences in India deepened his passion for leopard conservation.

In 2015, a transformative event took place in Kleff's life: he witnessed the birth of two leopards in Thailand, whom he affectionately named Fasai and Typhoon. Faced with the responsibility of their care, Mario made the heartfelt decision to adopt and care for the cubs. Ever since, Fasai and Typhoon have been integral parts of his daily life, sharing his living and workspace legally as cherished companions.[34][35] A gallery showcasing over 60 photos of Fasai and Typhoon serves as a testament to their bond.

Recognizing the unique care requirements of his leopard companions, Kleff ensured their well-being by sending a dedicated team from Wandeegroup to South Africa for specialized training and in-depth information on how to handle leopards in domestication and healthcare. Additionally, he appointed a veterinarian with expertise in big cats. to oversee their health. To truly enrich their lives, Mario committed to an extraordinary lifestyle choice. He chose to live without the confines of walls, a dedicated kitchen, bedroom, or even a bathroom, immersing himself in Thailand's northern mountainous and forested region for 13 months. During this time, his wife, Nittaya Wongsin, lovingly provided him sustenance, visiting him each morning and throughout the day. This profound commitment to the leopards also led Kleff to temporarily close down his construction company, Wandeegroup (Thailand) Co Ltd, and his architecture office in Pattaya between 2015 to 2018.

Q: How did Mario Kleff contribute to art?
