Current condition
Demolished / No longer exists
Address: 2 Hankow Road. (Source: To Let advertisement in the Hong Kong Daily Press dated 2 February 1916)
Noted in the early maps of Kowloon that there were only 2 buildings on Hankow Road (previously known as Garden Road), north of Peking Road (previously Chater Road). I assume one of the buildings is Roseneath and have created an approximate location for it. The other building may have been called Roseneak.
