Kamthieng House Museum

Kamthieng House Museum is a traditional northern Thai house museum located within the Siam Society Under Royal Patronage compound on Sukhumvit 21 (Asok) in Watthana, Bangkok. The 19th-century teak stilt house was originally built in Chiang Mai and relocated to Bangkok in 1964. It is notable as a well-preserved example of Lanna vernacular architecture and houses an ethnographic collection illustrating rural northern Thai life.

Visitors can expect a traditional Lanna teak house raised on stilts set in a landscaped garden within the Siam Society compound. The house interior displays period tools, household utensils, textiles, and agricultural implements arranged to show traditional northern Thai domestic life. Visitors explore the main house, a rice granary, and open verandas with guided explanation. The setting is quiet and shaded, contrasting with the surrounding Sukhumvit commercial area.

The house was built in the mid-19th century in Chiang Mai along the Ping River and belonged to the family of Mae Kamthieng. It was donated to The Siam Society by descendants of the Nimmanhaeminda family and reassembled in Bangkok in 1964 under the supervision of architect Vira Rambhason. It represents a rare surviving example of traditional Lanna domestic architecture from that period.

The museum preserves and presents Lanna cultural heritage and traditional northern Thai rural lifestyle, including domestic architecture, crafts, textiles, and agricultural practices. As a project of The Siam Society Under Royal Patronage, it serves as an educational resource for Thai vernacular architecture and ethnography.
