The architectural style of the building is “International Modernism”, the main features of which are cubic shapes, flat roof, white walls, steel windows, horizontal projected canopies and ornamental ironwork balustrade. Windows are fitted with ornamental ironwork grilles that follow strict symmetric alignment. The side facing School Street has the central portion slightly moved inside to highlight the three-partition design. The additional elements during the re-construction in 1949 demonstrated the major “Art Deco” architectural style. Internally, the rooms are plain and devoid of architectural detail.
In short, the building is utilitarian and functional according to the dictates of modernism. As the building has undergone re-construction, the materials used in the ground floor were different from the ones used in other floors. One example was only the ground floor had granite columns.
As the original staircase does not comply with the latest requirement of the Fire Safety (Buildings) Ordinance, a new exit staircase is built inside the building. Due to the narrow working space, it brought about special challenges to the construction team to overcome.
