Organization permissions should be managed via Control Panel. Further Organization configuration is managed in the Foundry Settings tab.

When Foundry home folders are enabled, they are automatically marked with the organization of the user.
Configuration options to disable home folders are in the beta phase of development and may not be available on your enrollment. Functionality may change during active development. Contact Palantir Support to request access to this feature.
Spaces have been rebranded from their previous name, namespaces.
Spaces settings are managed in Control Panel on the Space management page of enrollment settings.

From the Space management page, select + Create space.
As part of space creation, you will be asked to specify the following settings:
Project defaults, but you can use a custom role set instead. Note: If you use a custom role set, space-level roles will not automatically apply to projects.If you are an enrollment admin but are not able to create a new space, it may be because your enrollment is not suitable or you have hit a quota limit; contact Palantir Support for more information.
In the Actions section, you can Manage the settings of a space. You can configure which organizations can access this space, the deletion policy, the filesystem, and the role set used for projects in this space.

Legacy spaces might provide additional configuration settings. Below is a description of those settings:
