Nice, Puddin! And to all the detectives giving it a try!
It isn't
exactly that building though; I was told something about the Vimanmek Teak Palace, in the same compound, but no photography is allowed inside?!
So I'm not exactly sure if TAR could have got their cameras in too! (A security guard seemed to remember filming in the compound though, the information desk - when I asked them - called up someone, then started pretending to not know anything...)
