Architect With A Mission

From the drawing board to the showroom until the completion of the unit


Standards that ain't standards:
Don’t judge a book by its cover has been a good advice since Gutenberg started mass production of literature. If you apply this thinking to the real estate market in Pattaya, you would say: Don’t judge a condo by the showroom! The word showroom is intended to indicate that the room will show potential buyers what the architect has designed and they will later get built. Most of the brochures and renders already have a statement of caution: artist impression only, reality can differ.
So every time I see some of these creative visualisations, I ask myself why the developers so underestimate the intelligence of their customers. I think that customers deserve a better and more respectful treatment – no restaurant would dare to put the lobster on the menu and then proudly serve a couple of shrimps and ask the guest, how was it?
Maybe not everyone will agree and some people think that the more difficult the times are, the more they have to exaggerate their claims. How else could there be people trying to sell a 21 sqm box as a luxurious studio? Or present a plain vanilla standard design tower as "the most luxurious building ever to come to Pattaya ". The guys must have gone nuts.
Call for a quality consensus:
In the near future, Pattaya doesn’t need quick deals to the detriment of naive customers, but careful planning and honesty from the drawing board to the final product being transferred. I am saying this not to divide the market into "the good, the bad and the ugly" but to put the facts on the table and unite the industry for its own benefit. I call for a quality consensus of real estate professionals here in Pattaya, where codes and conducts are agreed to protect the customer – and therefore ultimately the agents and developers who can still look into the eyes of their clients after the development is finished.
Fewer pillars on the plan:
Most floor plans are spacious and with large open spaces. Fewer pillars and smart engineering are the solutions of the architect Mario Kleff.
Higher quality on the market:
In 2022 there is no high-end market for real estate development in Pattaya. For over a decade Mario Kleff tried intensively with new ideas and modern design to convince developers to inject better quality on the market.
Improved construction:
Mario Kleff is the founder and the CEO of Wandeegroup Asia Co Ltd, a Pattaya construction firm, which serves first-class processing, advanced technical backup and detailed knowledge of the construction standards for any kind of building.
Cellular beam in Thailand:
The use of the cellular beam in the construction of buildings brings a significant advantage in the construction costs. The cellular beam is also an eye-catcher in the design of modern architecture. Mario Kleff introduced the cellular beam in Thailand in 2007. Since then, numerous real estate developments have been built with the cellular beam and post-tensioned concrete floors in the form of multi-storey modern residential buildings and luxurious villas.
One way or another:
In Germany, Bauhaus and modern architecture was the most inspiring design for the young Mario. He loved the appearance and the idea to create clean environment and infrastructure. In addition to classic education in history and in the elementary design teaching of the old masters in architecture, music and art, Mario Kleff studied Asian aesthetics and contemporary Japanese architecture. Today, Pattaya-based architect Mario Kleff specializes in minimalist and brutalist architecture.

Mario Kleff's first structure is the Villa Futureproof, which was designed in 2004.
