This building is part of the Staff Quarters Compound, together with the Senior Staff Quarters (built 1905) and the No. 2 Staff Quarters (built 1936) and some outbuildings. They are currently awaiting revitalisation.
"The Staff Quarters for the engine-drivers and stokers is situated at the west end of the Pumping Station. It consists of a two-storey quarters and a single storey store building which are connected by a covered walkway. The two buildings share a similar design, the staff quarters is long, narrow and rectangular in shape, with open verandahs facing the seaside while the store building is built rectangular in shape at a slight angle to the quarters, with open verandahs facing the hillside. Open concrete stairways are constructed at both ends of the verandah for the quarters. Both building facades have been painted, but probably originally they were exposed red brickwork matching the Pumping Station. The roof of quarters is hipped, finished with double-layered pan and roll tiles while the roof of the store building is mono-pitched with asphalt finishes. Windows on both buildings are segmental arched wooden casements. Jack arch interior slabs are constructed at floor slabs of 1/F which are not commonly use in Hong Kong nowadays."

(In 2019) "The Main Building of Staff Quarters appears to be in dilapidated condition. Temporary metal supports are installed in the front elevation which provides support to the roof structure. Paint peeling, concrete spalling and rusted reinforcement can be seen within the building. The Store Building of the Staff Quarters appears to be in fair condition. Damage of some finishes can be observed." (Revitalising Historic Buildings Through Partnership Scheme - Tai Tam Tuk Raw Water Pumping Station Staff Quarters Compound - Resource Kit', Nov 2019, p. 8)
