Can I build my own house in Thailand on a marriage or retirement visa without it being classified as work?

The question addresses whether building a personal residence in Thailand would be classified as working, especially when holding a marriage or retirement visa. Responses indicate that you cannot own property outright as a foreigner; properties like houses would be in your Thai spouse's name. It’s suggested that while you may supervise the building process, it generally wouldn't require a work permit, and choosing a retirement visa might be easier than a marriage visa unless employment is intended.
