15-19, Queen's Road Central.
Some notes I've found about this building:
1935. The 3rd Dec edition of the HK Telegraph reports that Marina House is complete:
"With every modern convenience and imposing in design, the new building next to the Hongkong Hotel in Queen's Road Central, to be called "Marina House", is now completed and will be ready for tenants to move in on January 1, 1936.
