Eight houses built on Marine Lot 12, the address is 26-33 Connaught Road Central. Probably built at the same time as houses 34, 35, 36, 37 Connnaught Road Central (on ML 13). As a guess the construction date was set to 1905.
The houses can be seen on this map:
Buildings on Marine Lots 62 and 10a = 15-23, Connaught Road. David gave them their name: Nine Arches Buildings.
They were built shortly after central reclamation finished. The left 3 houses were occupied by the South China Morning Post, their offices were occupied on 1 June 1903 (see comment below).
I recently found this panorama over on the Historical photos of China site. The caption had it dated 1875 but it is much earlier, probably 1864-1865 as the large building under construction in the centre is Dent's new headquarters which was completed c1866.
