Building east of the Harbour Office (4th gen.). It streches out from Des Voeux Road Central to Connaught Road (then waterfront), the additional address is 92-97 Connaught Road. It appears first on the 1957 map on hkmaps.hk as "building under construction". On the roof it had a sign "SEIKO".
It was replaced by Li Po Chun Chambers that opened in 1995, so it was probably demolished in 1993.
Addendum 2022-12-30: The 1960 map also gives the name of the building as " Li Po Chun Chambers", so both buildings had the same name.
