The report presents a review of national best practices summarized in fact sheets, a description of achieved benefits and barriers of the roof top extension projects and finally a project gallery with selected projects.
The collection and analysis of case studies can function as guide for architects and engineers. The project gallery is meant to disseminate all knowledge, not only among experts; it can also be a very useful mean to show reserved occupants what the opportunities of roof top extension are.
