Architects 49 was established in 1983 by Nithi Sthapitanonda. From the beginning, his vision has always been timeless architecture with clean, simple, elegant lines. With a keen interest in Thai art and architecture, our founder has laid the foundation for present generations to follow. This enables Architects 49 to work with clients from the beginning of a project through to its successful operation.


Our Approach

Our experienced team, several of whom have been with A49 for over 20 years, ensure the practical and economical aspects of the project are met. Fresh ideas from the younger generations are always incorporated into the concept stage. The nature of this team approach has long been our hallmark.


Our Work

The diversity of our team enables us to create a broad range of architectural styles. From modern and striking, to contemporary and traditional. We approach each project differently and believe that each one should have its own distinctive character.



Architects 49 has, over the years, garnered a number of awards both locally and internationally, dating as far back as 1987.

National Artist of Thailand in Architecture

Nithi Sthapitanonda

National Artist of Thailand in Architecture

Our founder, Nithi Sthapitanonda, an alumnus of Chulalongkorn University and University of Illinois at Urbana-Champaign, founded Architects 49 in 1983. During his years at A49, he has held the position of President of the Association of Siamese Architects under Royal Patronage between 1992-1994 and the Secretary General for the Architect Council of Thailand from 2000-2002. In 2002, he received the honor of being named by the Ministry of Culture as a “National Artist” in Contemporary Architecture.

Nithi was appointed Honorary Member of the Japan Institute of Architects (JIA) in 1995 and Honorary Fellow of the American Institute of Architects (AIA) in the USA in 2008. In 2013, he received an Honorary Doctorate in Science in the field of Architecture from Sripatum University. Additionally, he has served on a number of boards and acted as a trustee for various organizations. Nithi has also chaired several judging committees for numerous prestigious awards, ranging from the Thai Ministry of Culture to Silpakorn University.

A prolific master of drawing, Nithi has, over the past 40 years, collated a vast collection of his own ink drawings from his early school years onwards. He has developed a style and technique in pen and ink drawing that is well recognized among Thai architects and students. Approaching his retirement from A49, Nithi started Li-Zenn Publishing Limited, the publishing company of his dreams, and began to work on the design of religious buildings. Over the last ten years he has designed a number of wats (temples) and stupas, a few of which have received awards from the ASA. In undertaking such works, he has re-established a public interest in Thai religious architecture, long absent from local scene.
