Please see Delete or Restore a Page in the Confluence documentation for information on how to restore a deleted page.
Unfortunately, there's no easy way to restore a deleted space. For that, we recommend asking your Confluence Administrator to restore the most recent site backup so that you can retrieve the deleted space from there.
To setup Confluence in a staging environment (for restoring a backup, for example), you're welcome to use a Developer License.
