The late Silaban designed Thamrin Building of Bank Indonesia with a strong pattern as accent, as seen in the vertical columns filled with an array of square shapes that forms a grid which functions as sunscreen around the building. The grid covers large glasses inside. This pattern appears strong and in contrast with the saddle roof, which actually was about to be removed by then President Soekarno during the building’s construction. It is in this main building that the Governor of Bank Indonesia works and the area is not open for public, except for the press conference area for reporters and journalists. Therefore it is our great honor to be able to capture images of the building’s interior throughout the main lobby that faces Jalan M.H. Thamrin.
