Noise Control
If an office is designed and organized so that office activities based on noise-level could be grouped together, productivity would probably increase. For example, spaces closer to the main entrance would be better for meetings, the kitchen area or other louder activities.
As you go deeper into the office, noise levels should become quieter where employees are more able to get their work done. Those employees coming from a home office will need to transition from the solidarity at home to an office environment with many distractions.
