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.

The items to be conserved during the revitalization works include:

1. Stone tablets commemorating the founding of “Hung Shing Yi Hok” in Qing Dynasty at G/F level.
2. Stone tablet commemorating the re-opening of the school beside the main entrance, being the calligraphy of Mr. Li Wai-tong.
3. Timber fanlight and the door frame of the door opening facing School Street.
4. Ornamental ironwork balustrade at 2/F balcony.
5. Staircase and continuous balustrade leading from G/F to roof.
6. Wooden floor at the ground floor and windows. Rectangular grid pattern steel windows with ornamental ironwork grilles and wired hexagonal pattern glass panes, and metal ironmongeries including locking handles and window stays.
7. Cast iron rain water pipes with hopper heads at the outside of the building.

As the original entrance at School Street is a key conservation item, the main entrance after revitalization will be relocated to First Lane. A new lift will be constructed at First Lane to comply with barrier-free assessment requirements. The lift tower will be decorated with lighting elements and a large “Dragon Ball” on the roof to provide lighting effects simulating the fire dragon dance, so as to establish a new landmark at Tai Hang.

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.
