Engineer's Office of the Former Pumping Station, Grade I historic office in Yau Tsim Mong District, Hong Kong

The Engineer's Office of the Former Pumping Station is a two-story red brick structure with decorative brickwork, iron railings, and Neo-Classical architectural details on its facade. The building stands on Shanghai Street and displays the craftsmanship characteristic of colonial construction methods.

Built in 1895, the Engineer's Office was the sole survivor of a pumping station complex of three two-storey buildings and a tall boiler chimney. Its steam pumps, imported from England, drew about 400,000 gallons a day from three nearby wells. The station stopped operating in 1911 and the chimney was demolished a year later.

The building reflects colonial engineering heritage and shows how water systems shaped Kowloon's growth. It stands as the sole remaining structure from Hong Kong's original water pumping complex and demonstrates the technical innovation of that era.

The Red Brick House stands at 344 Shanghai Street, next to the Yau Ma Tei Theatre; the two are linked as a Cantonese opera venue, and guided tours have taken visitors through both. Since 2016 the building has housed the theatre's office, rehearsal rooms and a small shop selling Chinese opera souvenirs.

The building's original identity had been forgotten by 2000, when it was known simply as the "Red Brick House" and slated for demolition for the No. 8 Waterloo Road project. The developer cancelled some lower-floor units and supported the tower on long columns to keep it standing.
