you are so close, yet so far..Damn...looks experimental.
The only hint I can see is the "Chill out Room" written behind
Which might indicate its presence in a university, which might indicate that it had a rather interesting airframe.
Bang on Pintu, good. It is Heinkel He 178, first jet to fly under turbojet power.Other is Nazi He 178 but as Luftwaffe marks are not on it so I am guessing Gloster E 28 , I may be wrong.

Thanks DD, I gave the hint , in the image zoom in on the sign board, and see the word 'CONDA'
