The problem between protection and urban planning was supposed to be solved by writing Special Plans for the Protection for Architectural Heritage and Catalogue, which were adapted to the city districts and finally approved throughout 2000.
These Special Plans have been extended to the present with numerous plans that have increased the protection of buildings, as we can see in the industrial heritage, the emblematic spaces, the plans for Sant Andreu, Poblenou, Horta, Gràcia,... and more in the future.
This solution has enabled to coordinate protection and planning criteria, so that protection now more effective and suitable.
Special Plans set four levels of protection:
- The first categoy includes A Level elements (National Cultural Heritage), which are determined by the Government.
- The next category are formed by those elements of the B Level (Local Cultural Heritage), which are determined by the Council and ratified by the Government of Catalonia.
- The City Hall is responsible for elements belonging C Level (Sites of Urban Interest).
- Finally, there are also the Level D elements (Sites of Documentary Interest).
For the first three categories maintenance is required and buildings cannot be demolished, while in D Level demolition is allowed after presenting a historical and architectural research, which has to be approved.
