Top photo: Cropped from Early Waterfront.jpg (ca. 1880)
Bottom Photo: Cropped from Wanchai's seafront in 1902
Some houses can be seen on both photos others have been demolished and rebuilt.
The Blue Buildings are already there, right of them no sign of the Sailors & Soldiers Home, so the upper photo is definitely older. 11&12 Praya East houses are on both photos, the ones between these and the Blue Buildings are different. 11&12 Praya East have scaffolds around them, possibly under construction and almost finished. The short pier in front of these buildings is visible on both photos.
Left is Fenwick Shipyard, much more developed on the bottom photo.
