From the late 1970s to 1987, TVB used the office of the former Commercial TV for additional studio space. This former Commercial Television Building is now RTHK Television House. In 1986 RTHK headquarters moved to here from across the road and renamed the building Television House.

The following changes occurred around te building since the 1981 – 1985 period:
The cave wall was demolished in the 1990s. The red pillars previously connected to the cave wall are currently owned only by commercial radio stations. After the cave wall was demolished, a solid white wall was built by moving left about two meters.
The two buildings of the previous TVB branch and commercial radio were connected. Now they are completely separated.
The six steps after entering the lobby of the previous TVB branch plant were at right angles and are now rounded. Maybe because of Feng Shui. These steps are famous as many group photos of TV-series were taken here.
There was in front of the golden wall a light yellow cuboid porter house. It has now been demolished. A new gatekeeper was built at the fence on the roadside after 2009.
Behind the six steps is the glass door with the TVB three-color logo. After entering, there are card punching machines. It is a revolving door.
At back you can see the red iron fence with underneath and a short white wall.
Many pictures were taken at this building.
