Since 1963
S+A is humbly the oldest architectural firm in Thailand.
The company was established in 1963 by prominent architect and academic M.L. Santhaya Israsena, who gave the company his name as well as his long-term vision. He led the company until his passing in the 80’s, quietly and diligently designing some of the first modernist buildings in Thailand.
He is succeeded by associated architect Suchet Chaorua. From 1984 until 2005, Suchet expanded S+A, producing some of the most iconic buildings in Bangkok and strengthen S+A as a forefront design practice in Thailand.
Faun Israsena is M.L. Santhaya’s grandson. He takes over the management in 2007 and is later joined by his partner Sophie Bughin in 2013. With their international backgrounds, Faun & Sophie strengthens S+A’s portfolio with focus on international clients and hospitality projects.
In recent years, S+A largely expanded both within Thailand and oversea, with the recent establishment of a branch office in Hong Kong and ongoing projects in various countries in Asia.
After 50+ years of continuous practice and 3 generations of leadership, the practice is still fully independent and privately owned by its associates.
