The existing auditorium's door openings have been preserved as much as possible to minimize construction costs. Sun tunnels have been installed in the corridor of offices A and B to introduce natural light. Inside these offices, frosted glass with backlighting has been used to create the impression of an outdoor environment.
Offices C and D already receive light from the south, and replacing the backlit walls with windows on the right and left sides would damage the soundproof panels. Therefore, the solution preferred for offices A and B has not been implemented here.
Additionally, I have shared a video and isometric details showcasing the design and lighting.
