Time Out says
An alternative art space, RMA Institute, is nestled in a quiet Sukhumvit neighbourhood just a few minutes off the Nana skytrain line.
The former grandma’s house was turned into an non-benefit art gallery named after ‘ar-ma’ (granny in Thai) as RMA offering a non-profit creative space featuring art exhibitions like photography as well as other media. RMA also provides regular creative workshops, artist talks, screenings, performances, and exhibition openings. Keep an eye on their website for the upcoming events.
