How do I close all the windows of a workspace?

[IvanPsy]

Greetings,

I usually work on projects, so I create a new space (workspace?) and open all the apps and windows there.

After the work session I close all of of them, and delete the workspace.

 

Is it possible to close all of the windows of the frontmost space?

I don't need to close the apps, as I work with the same apps on multiple projects, so I simple need to close only the windows contained in the frontmost space.

How about closing the space itself?

 

I'm trying to create a workflow for this, but with no results.
