The white house on the right looks pretty much like the Metropodle Hotel with the sign on the roof (unfortunately, can't read anything). Left of the hotel, two chimneys are visible. These can't belong to Taikoo Sugar - if so, they should be right of the hotel. Probably they belong to quarries located north of Taikoo Sugar.

Charles Gesner van der Voort had started his career in Rotterdam, at Holland-China Trading Company (HCHC). In 1938, he went to Shanghai for the firm. The Japanese interned him, and most other Dutch nationals, from 1943-45. In camp, he met his wife Nancy and they married after the war. After a leave in The Netherlands, they returned to the Orient, where Charles continued to work for HCHC in Hong Kong.
