In cases of ambiguity additional language must be used. On a ship terms like bow, stern, port and starboard tell a sailor exactly where they are. While white water rafting, the terms river right and river left are important to know. Pilots understand aircraft speed and wind speed are two different terms and critical to keeping a plane in the air safely.

A Building with a glass entrance:
A Lobby with glass behind the receptionist separates the public area with the ‘Employee Only’ area:
A Board Room within the ‘Employee Only’ area of the building:
Properly specifying glass graphics to avoid ambiguity.

A Board Room needs a company logo printed on a privacy band. The normal practice would be
The CEO of the business wants the logos to be readable from the inside – perhaps he constantly uses the video conferencing feature of the board room. Then the project would be:
*** Special note****

DO NOT SIMPLIFY.
Specifying clearly these 3 surfaces
