Thank you Paul
The unit is 1,000mm wide, 1400mm high and 500mm deep.
The back is going to be a mirror and 8mm plywood back.
As always, after the unit is finally located in place, I tie it to the wall with "L" brackets from above (habit from Japan, against earthquakes), and 2~4 screws coming from the lower cabinet (the unit will go over the TV stand).
