The so called "Ban Saonak". in the northern dialect refers to "a house which has many pillars", Mom Rachawongse Thanatsri Swasdhiwat named the house since it is a teak house with 116 pillars. The amount of pillars is very interesting. The house was built in 1895 by a Burmese man called Maung Chan Ong ( the ancestry of Chantarawirote family). The architectural style of the house was a combination of both Lanna and Burmese arts. Ban Saonak has been put into a must see list for architectural students from many institutions. Because of these visits it has become well know among groups of architects and designers countrywide. In 1996, the Siam Society publicized the story and history of the house to the worldwide context. Nowadays, the house has been opened as an art and cultural museum of Lampang province. Inside the house, antiquities are on display, such as Chao LuangLampang's hawdah, ancient trunks, some tools for pressing men's silk sarongs, iron coffers, silverware, and lacquerware. On the wall there are photos of Chao Dararasmi (the princess consort to King Chulalongkorn or King Rama V) and the first genaration of the house owners. Moreover, in the immediate vicinity of the house there is a barn with 24 pillars and a 150-year-old owery sarapee tree
