The Office of Siam Photon Laboratory is an expansion project of the National Synchrotron Research Center in Nakhon Ratchasima. The form of the building comes along with the function needed inside the building, which is according to the use of the office and laboratory. The well-ventilated open space in the middle creates a great welcoming approach to the users, which allows a decent amount of sunlight to enter the building. Since this building is connected with the old sphere shaped laboratory, the colors and materials of the building were chosen to match with the existing laboratory.
