Answer:
The five most popular would be the...
Cubicle Office layout. This is the most popular and is basically a box with an opening.
Open Office layout. This is several rows of large desks. By definition, it is not very enclosed.
Co-Working Office layout. Less common, these are offices rented out to employees by third parties.
Team-Cluster Office layout. For teams working on something, this is a good way to go. One table where you can easily work together on things with each other as you go.
Hybrid Office layout. This one is a mix of a few others and customizable to a workplace's specific needs. Some of these don't even feel like offices!
