Unfortunately, the provided article content consists entirely of technical CSS code and markup elements rather than journalistic text. The original French title suggests this article was about architecture students from Nancy who have developed plans to transform the Bourse du travail (Labor Exchange building), but no actual article content is available to rewrite.

To properly rewrite this article, the actual news content including details about the students' proposals, the current state of the Labor Exchange building, the scope of the transformation project, and quotes from involved parties would be needed.

Without access to the substantive article content, it is not possible to provide a complete and detailed rewrite that would meet the standards for comprehensive news reporting.
