Hello @feiderman, having a separate TV room instead of placing TV inside bedrooms has beneficial effects, according to studies, which will improve sleep. It's also effective to have a common recreational space for family and friends to gather together.

"I control the light with a vertical window located on one side, this helps me to control the light and at the same time place it in such a way that direct light is reflected on the wall and not on the sofa with people watching tv"

Great idea, nothing worse than natural light reflected directly on the screen.
All the best to your project
