17, Yuk Sau Street [c.1930- ]
An old building in Happy Valley.
The Home Affairs Dept database gives 1945 for the year built:
However, the year 1945 in this database seems to be code for "Built sometime before WW2, the records were lost in the war." Since #11 was built in 1930 and #15 in 1932, #17 was probably built around the same time.
