The fate of Tuen Mun's Red House is still hanging in the balance, after doubts were raised on Thursday about its supposed history as a secret base for Dr Sun Yat-sen, the founding father of modern China.
The Antiquities Advisory Board was told there's no direct link between the structure and the 1911 revolution that overthrew the Qing Dynasty.
Government findings presented to the board said any direct link remains in dispute.
At the moment, the building is protected from demolition after government heritage advisers declared it a proposed monument in March. That decision came after two of the building's windows were ripped out, raising concerns that the owner wants to redevelop the site.
But the proposed monument status is temporary, and it will expire in a few months' time.
The Red House is also a Grade One historic building. That's the highest in a three-tier grading system, but it doesn't guarantee the building won't be demolished.
