ANY ONE WORRIED ABOUT RL2 AND PROPERTY PURCHASES BELOW IS A STATEMENT OFF BRIAN REGARDING THE SUBJECT
The import of legacy elements (properties, avatars, clothing...) is still a long ways off into the future; however, when properties are imported, everything will come along - including space built outside. That is true even if the space was built without an official permission to do so
Nothing will be lost, so please have no worries about this matter.
