19 Middle Gap Road [1984- ]
This is HSBC's current taipan house at19 Middle Gap Road. I don't know the date of completion, but HSBC acquired it for $4,300,000 in 1973 from American Express.
The picture below shows No. 19 (red brick house w/ three chimneys). The other three houses are what is now 28 Middle Gap Road (House A, B, C). Can someone provide a picture of the old Mobil Oil house at No. 28?
